District heating out, Haier AW062 monobloc in: who will review my design and 13 open questions?
I'm replacing disconnected district heating (Eneco) with a Haier AW062MUGHA monobloc (6 kW, R290) with the ATW-A03N control box and the HW-WA101DBT wired controller. Hydraulics: Haier → 3-way valve → (a) a Haier WT60V 60 L buffer, connected in parallel (4 ports), with a second pump to 6 Jaga convectors, and (b) a Haier WT200V 200 L DHW tank (2.0 m² coil, 2.5 kW element). Room control stays Honeywell Evohome; the BDR91 goes volt-free to CN13 ZONE1 ON/OFF. An installation company does all the work (ISDE subsidy).
The Haier documentation leaves a few things open. Does anyone have experience with the ATW-A03N / HW-WA101DBT, or with a similar setup? The house has no heating and no hot water right now, so every tip helps.
How to reply: in the forum thread, with the question number (e.g. “V7: on mine K is 230 V during hot water, valve X …”). The numbers are the same as on the Dutch page (V = vraag, question). Click a number such as V7 to copy a direct link to that question, or use the reply template.

The 13 questions
Under each question: where the background is on this page, and which pages of the Haier documents I have already read. IM = R290 Monobloc installation manual (22-01-2025) · DB = Engineering DataBook (SYJS-07-2024 REV.B) · ATW = ATW-A03N installation manual (2025-04-03). Page numbers = printed numbers.
A. ATW-A03N control box and HW-WA101DBT controller
V1 Which tank-sensor input with a single tank sensor: T_tank up (CN50) or T_tank down (CN48)?
The ATW-A03N has two tank inputs: CN50 "T_tank up" and CN48 "T_tank down". The Haier WT200V has only one sensor pocket, low in the element flange. Which input does that one sensor go on? Does the controller show error E10 if the other input stays empty, and do you then have to switch something off in the menu?
Background: ATW-A03N connections · WT200V · schematic part (5). Documents: ATW p. 9 (CN48/CN50) · IM p. 39 (E10) · WT200V p. 6 and 8.
V2 Which setting makes the BDR91 on CN13 ZONE1 ON/OFF work?
I want Evohome (BDR91, volt-free contact) to switch CN13 ZONE1 ON/OFF. The installer menu has "Control Mode of Zone1": Main controller / Third party controller / Thermostat, and "Third Party Controller Type": Type 1 / Type 2. I think: Third party controller, Type 2, with the HEAT/COOL contact left open (= heating). Is that right? Does the compressor stop immediately when ZONE1 opens, or does it finish charging the buffer first?
Background: Evohome · settings. Documents: IM p. 57–58 · DB p. 69 (third-party control, Type 1/2) · ATW p. 11–12.
V3 Short cycling caused by Evohome: any experience with BDR91 → ZONE1 ON/OFF and a parallel buffer?
Even at its lowest setting, Evohome switches the BDR91 3 times per hour (TPI, min. ON 5 min). Has anyone measured whether a Haier then short-cycles, even with a 60 L parallel buffer? My fallback: ZONE1 permanently on in winter, and the BDR91 only switches pump 2 (PUMP1 output → BDR91 COM/NO → pump 2). Is the BDR91 contact suitable for a ≈ 45 W pump at 230 V?
V4 How should the Haier's internal pump be set with a parallel buffer, and does pump 2 keep running during hot-water charging?
"Indoor unit installation" has "Pump Flow Rate Control Mode" (ΔT between out and in water / Constant speed duty out; default Constant speed) and "IDU Pump Duty Out" (0–100 %, default 0 %). What does 0 % mean: maximum, automatic or off? I want a fixed ≈ 1.0 m³/h (primary ≥ secondary). And: does the PUMP1 output (pump 2, radiators) stay on while the tank is being heated?
V5 Does "Schedule" also work for hot water (time window 11:00–15:00)?
I want the tank to heat only between 11:00 and 15:00 (solar panels), but still reheat in the evening if it really runs empty. Can "Schedule" (time block with mode and temperature) do that, e.g. DHW 48 °C from 11 to 15 h and ≈ 41 °C the rest of the day? Or is the SG-ready input (CN47) with a timer switch better?
Background: solar vs. heat pump · settings. Documents: IM p. 49–50 (Schedule), p. 56 (SG Ready), p. 57 (Tank Re-heat Temp.) · ATW p. 11–12.
V6 Energy meter on CN52: which kWh meter with pulse output?
The Haier can show its own consumption with an external pulse meter on CN52 EM ("Pulse Selection for power consumption": 1/10, 1/1, 10/, 100/kWh). Does the HomeWizard 1-phase kWh meter have a pulse output (S0), or should I take an Eastron SDM120? Has anyone connected this?
V7 3-way valve direction: does the Haier put 230 V on K for hot water?
The ATW-A03N has terminals L, N, K ("live, neutral, control") for the 3-way valve. Is K = 230 V during hot water (and K = 0 during space heating)? Haier's own example drawing calls the tank port "A" and the buffer port "B", the opposite of many valves. Which valve do you use with a Haier (e.g. Rekx OKO1, VC6013 type), and did you have to change anything on it?
V8 Floor-heating group without a (known) oxygen barrier: is a plate heat exchanger needed?
The house has an old WTH floor-heating unit (own Grundfos UPS 25-40, thermostatic mixing valve) for the bathroom floor, unused for 4 years. If the blue floor pipe has no oxygen barrier (no print "EVOH / zuurstofdicht / DIN 4726"): is a small plate heat exchanger really needed, or would something else do? And can such a group with its own pump simply go on the secondary side of the buffer (next to the radiators)?
V9 Do the Haier sensors (0150408957) fit the WT200V sensor pocket and the WT60V measuring port?
Has anyone fitted the supplied Haier temperature sensors (part no. 0150408957) into a Haier WT200V (pocket in the flange) and a Haier WT60V (front measuring port)? What is the sensor diameter, and did you need an adapter or thermal paste?
Background: tank & buffer · schematic parts (4) and (5). Documents: DB p. 129 · WT200V p. 8 · WT60V p. 2.
C. Tank element and electrical
V10 Which thermostat of the WT200V element is adjustable (RT or MT), and how high?
According to its wiring diagram, the 2.5 kW element of the Haier WT200V has two thermostats in series: RT ("normal temperature thermostat") and MT (in German "manueller Thermostat"). Which one is adjustable, and up to what temperature? I want the anti-legionella cycle at 60 °C (default is 75 °C), so the adjustable thermostat must be at least 65 °C. Is MT a manual-reset safety cut-out?
Background: WT200V · Sterilization. Documents: WT200V p. 5 (MT/RT/EH/HL) · IM p. 54 (Sterilization 50–75 °C, default Mon 23:00, 75 °C).
V11 Cable type: XMvK/YMvK or H07RN-F to the outdoor unit?
Haier specifies H07RN-F "or the electrically equivalent type" for the power and interconnection cables. Can the fixed run to the front facade be XMvK/YMvK 3 × 4 mm², with only the last flexible part in H07RN-F? What do installers do in practice (NEN 1010)?
Background: sub-panel, E2/E5. Documents: IM p. 7 and from p. 29 · DB p. 19 (min. 4 mm², MCA 13.5 A, MFA 16 A).
D. Other
V12 Jaga convectors at 45–55 °C: enough output in the coldest rooms?
My Jaga's were sized for district heating (≈ 70 °C). The smallest: 10.5 × 72 cm (coldest room, top floor) and 20 × 72 cm. Who has experience with Jaga's at 45–55 °C supply? Is a DBE booster or a bigger Jaga usually needed?
V13 Price check: 20 A RCBO type A, ≥ 30 mm insulation, raised stand
Is ≈ €30–55 right for an RCBO 20 A, 30 mA, type A, 1P+N (Hager ADA920G / ABB DS201 B20 A30), ≈ €60–110 for 10 m of 30 mm insulation, and ≈ €20–50 for a raised stand for the outdoor unit? Where do you buy these cheapest?
Background: parts & cost. Documents: IM p. 26 (insulation ≥ 30 mm), p. 19–20 (placement).
Also welcome: comments on the parts choice (tank, buffer, 3-way valve, pump, anti-freeze valves), or on anything I've completely overlooked.

The meditation room is the coldest: it has one more outside wall than the others. The other rooms border heated neighbours.
Front facade from above. Yellow = meditation room (2nd floor, under the roof, coldest room), green = bedroom 2. Solar panels on the roof.
Heat demand from the real consumption
18 GJ/year of district heat (steady for 4 years) = ≈ 5,000 kWh, for space heating and tap water together.
Tap water: 11 showers/week (2 adults, 2 teenagers), 8 L/min → ≈ 970 kWh; kitchen ≈ 225 kWh; losses of the old set ≈ 330 kWh → ≈ 1,530 kWh.
Space heating ≈ 3,470 kWh/year ÷ 1,400–1,800 full-load hours → ≈ 1.9–2.5 kW, with margin 2–3 kW on the coldest day.
A rough per-room estimate (everything 20 °C all day) gives 4.1–5.1 kW at −6 °C; real use is more economical (zoning, cool bedrooms).
The installer will do a heat-loss calculation (ISSO 51).

Source: Engineering DataBook. Minimum output ≈ 1.2–1.6 kW, while the house needs only 0.3–1 kW in spring and autumn. That is why there is a buffer.
The pipes in the meter cupboard
The rail has four capped connections, stamped KW – WW – A – R: 1 cold water in, 2 hot water to the taps, 3 radiator supply, 4 radiator return. The old Honeywell VC8015 zone valve on pipe 4 is replaced by a straight coupling. The fitting under pipe 1 is the old, weeping inlet safety group (inlaatcombinatie); it is replaced, and its drain to the sewer is reused.
2. Hydraulic design (Plan B)
Principle schematic v7 (click to enlarge; click again for 100 %). It shows how everything is connected, not where it stands. Port heights in mm above the floor, from the Haier drawings (±10 %).
Impression of the end result
AI impression, not a photo. This is roughly how it should look; nothing has been installed yet. The schematic above is leading.
Without numbers. Left the outdoor unit on a raised stand, middle the storage room with buffer and tank, right the meter cupboard.With numbers (roughly following the schematic). Some labels don't match the design: "8" appears twice and "15" three times; "16" and "17" (pressure gauge and filling set) sit on top of the buffer; "4" (the buffer sensor) points at a pressure gauge; "E6" points at an existing box instead of the kWh meter in the new sub-panel. The design itself is fine; only the picture is off.
Principle: two loops with a parallel buffer
Loop 1, Haier ↔ buffer / tank coil. The Haier's internal pump (PUMP_0, "pump 1") runs ≈ 1.0 m³/h. Nothing in loop 1 can close. The 3-way valve sits right after the Haier: heating port → buffer, DHW port → tank coil. Ports are named by function here, because the letters differ per manufacturer (V7).
Loop 2, buffer ↔ radiators. Pump 2 (Wilo Para 25/6, Δp-v, 0.6–0.8 m³/h) draws from the WT60V's upper right port and feeds pipe 3. The return (pipe 4) goes only into the lower right port, never directly into the Haier return.
WT60V 60 L in parallel (4 × 1¼"): separates the loops, covers defrost, and gives ≈ 1 start per hour at low load (6 K switching band ≈ 0.42 kWh per cycle).
WT200V 200 L: 2.0 m² coil in counter-flow (in at 930 mm, out at 290 mm). Tank at 48 °C, preferably heated between 11 and 15 h. Anti-legionella: Sunday 13:00 to 60 °C, the last degrees by the 2.5 kW element via the built-in relay of the ATW-A03N.
Common return (J1): 18 L expansion vessel (pre-charge 1.0 bar, capped valve) → Dirtmag → Y-filter → Haier.
A specialist who visited on 3 November drew the same principle (photos).

Water volume and expansion vessel
Radiators ≈ 8–14 L, pipes ≈ 15–20 L, buffer 60 L, coil ≈ 10–12 L, Haier + outdoor pipes ≈ 5–10 L → ≈ 100–115 L (phase 2 with floor loops ≈ 130 L). Expansion 10 → 75 °C ≈ 3.0 L + 3.0 L reserve. Static height 6 m → pre-charge 1.0 bar; pe 2.5 bar (safety valve 3 bar) → usable fraction 0.43 → ≈ 14 L total − 4.5 L built-in ≈ 9.5 L → chosen 18 L. Haier: the built-in 4.5 L vessel covers max. 78 L (IM p. 26). Fill pressure 1.5 bar cold, 1.8–2.2 bar warm.

Division of tasks
Evohome decides which rooms get heat and whether heat is needed. The Haier decides how warm (heating curve), keeps buffer and tank at temperature and switches pump 2 (CN37 PUMP1).

Fallback
Fallback: ZONE1 permanently on during the heating season, so the Haier controls on T_buffer only. The BDR91 contact moves into the live of pump 2: CN37 PUMP1 L → BDR91 COM → NO → pump 2. Pump 2 then runs only when the Haier allows it and Evohome asks for heat (V3).

Placement: side by side on the floor in the storage room at the front (floor plan), as close to the meter cupboard as possible (≈ 1.2 m wall width, 0.65 m deep). Stacking the buffer on the tank was ruled out: ≈ 2.6 m high, and the anode can't be reached. A combined tower was ruled out too: no reliable seller.
Drinking-water side: new KIWA inlet safety group 8 bar; T&P valve on ②; thermostatic mixing valve 50–55 °C on ① (cold taken after the inlet safety group); weekly anti-legionella cycle ≥ 60 °C. Each heat-up drips ≈ 3 L from the overflow; a drinking-water expansion vessel (21) is optional.
5. Existing floor heating (WTH group)
In a cupboard ≈ 1.5 m from the meter-cupboard pipes is a red WTH floor-heating manifold with its own Grundfos UPS 25-40 180 (30/45/60 W, unplugged), a thermostatic mixing valve with sensor (setting 5), a second thermostatic head on the return, and supply/return thermometers. It is connected by a tee to pipes 3 and 4. It probably heats the bathroom floor (still to confirm with the former owner). It hasn't been used for 4 years.
Phase
What happens
Winter 2026–27
The group's valves are closed (or two ball valves are fitted on the tee). Its old water stays out of the new system and the pump stays off.
Spring 2027
Flush the loops separately; replace the pump (Wilo Para / UPM3, 180 mm). Oxygen barrier: with the print "EVOH / zuurstofdicht / DIN 4726" or Alu-PEX, connect directly; otherwise separate with a small plate heat exchanger (V8). Let the pump run only together with pump 2; mixing valve at ≈ 30–35 °C.
Effect on the design: ≈ 5–15 L extra water; the 18 L expansion vessel is still enough (≈ 10.5 L needed).

7. Outdoor unit
Planned position of the Haier against the front facade, behind the fence and next to the storage-room door.Ground-floor plan (front). The tank and buffer (two circles) go in the storage room, right behind the outdoor unit, so the pipes into the house stay short.
Location: front of the house; the neighbours agree.
Noise: limit 40 dB(A) at night / 45 dB(A) by day at the property boundary (Bbl). AW062 sound power 58 dB(A) → Quiet mode 22:00–07:00, on the 6 supplied rubber dampers and a raised stand.
Clearances (IM p. 20): ≥ 250 mm behind the unit, ≥ 1,000 mm free in front of the fan, top open.
R290 (IM p. 25): not under a window or door, not near basement windows, ventilation openings or a street drain, not near sockets or outdoor lights.
Condensate and defrost water to a gravel soak-away, not onto the pavement (ice) and not into a drain close to the unit.
Pipes through the front facade with UV-resistant insulation ≥ 30 mm; anti-freeze valves low and close to the unit. The Haier has ≈ 66 kPa available head at 1.03 m³/h (loop 1 needs ≈ 25–35 kPa).
8. Parts and cost
The installation company installs everything (required for ISDE); I may buy the materials myself. ✅ = my pick. Prices incl. VAT, checked 2–4 November 2026.
Not included: the installation company's labour, the optional drinking-water expansion vessel (€40–60), floor-heating phase 2 (≈ €175–540). Already in the boxes: Y-filter, 3 sensors, controller, ATW-A03N, 6 rubber dampers, drain elbow (Haier); T&P valve (WT200V); magnesium rod (WT60V).
Planning: 3–4 quotes this week. Order tank and buffer as soon as an installer accepts customer-supplied Haier tanks. Other parts before ≈ 10 November. No delivery date before ≈ 20 November → Dutch fallback. Goal: warm before 20 December.
9. All open points in one table
What no Haier document settles. Points with a question number are on the forum; the rest I settle myself or with the installer.
Hour-by-hour simulation of an average year with the real monthly yield (5,520 kWh), KNMI climate normals for the region, 3,470 kWh space heating and ≈ 1,195 kWh tap water:
Heat pump ≈ 1,600 kWh/year, ≈ 75 % of it in November–March.
Heating the tank between 11 and 15 h: 627 kWh (39 %) directly from the panels, against 305 kWh when heating in the evening. Hence V5.
Net metering (saldering) ends on 1 Jan 2027, so direct self-consumption becomes more important.
In December/January the panels cover only 15–20 % of the heat pump.
