Commissioning checklist

Commissioning checklist/Check off measures carried out
1. Supply indoor unit and outdoor unit (if present) with voltage
2. Enter "Expert code"
3. Set the operating parameters
[→ Configuration Wizard → Setting parameters]
[Hot water temperature target 1]
▪ Do not set below 40 °C during commissioning.
▪ Never set below 35 °C after commissioning!
4. Activate the ventilation function
▪ Check the water pressure
▪ Checking the minimum flow
5. Activate the "Heating" operating mode
Observe the waiting time (up to 5 min)
▪ For outside temperatures below -2 °C and a storage temperature below
30 °C
▪ For outside temperatures below 12 °C and a storage tank temperature below
23 °C
▪ In this case, the storage tank is heated with the help of the backup heater.
6.
Commissioning is complete when a DHW temperature
40 °C appears on the display.
7. [Screed drying] (if necessary)
Screed drying only after commissioning is complete. As soon as the temperat-
ure of the storage tank is at least 40 °C, activate (also possible without outdoor
unit).

Re-commissioning

5.2.1

Requirements

CAUTION
Commissioning in frosty conditions can result in damage to
the entire heating system.
▪ Commissioning at temperatures below 0 °C only if a wa-
ter temperature of at least 5 °C is guaranteed in the
heating system and the storage tank.
▪ We recommend not to operate the installation in ex-
tremely frosty conditions.
▪ The indoor unit is fully connected.
▪ The refrigerant system is dehumidified and filled with the specified
amount of refrigerant.
▪ The heating and hot water system has been filled and pressurised
to the correct pressure (see Chap.
▪ The storage tank is filled up to the overflow

INFORMATION
If the storage tank temperature falls below specific min-
imum values, the safety settings of the indoor unit prevent
the heat pump from being operated at low outside temper-
atures
- Outside temperature < -2 °C, minimum storage tank tem-
perature = 30 °C
- Outside temperature < 12 °C, minimum storage tank tem-
perature = 23 °C
Without backup heater:
The storage tank water must be heated to the required
minimum storage tank temperature with an external heater
booster.
With backup heater (EKBUxx):
At an outside temperature of < 12 °C and a storage tank
temperature of < 35 °C, the backup heater (EKBUxx) is
automatically switched on to heat the storage tank water to
at least 35 °C.
▪ To accelerate the heating process with backup heater,
temporarily set the [Config. of external heat source]
parameter = "1" and the [Ext. hot water power] para-
meter to the maximum value of the backup heater
[→ Main menu → Settings → Ext. source].
▪ In the [User] menu, select and switch on the [1x Hot Wa-
ter] parameter. After heating, switch the parameter off
again [→ Main menu → User → 1x load].
1 Check the cold water connection and, where necessary, fill the
potable water heat exchanger.
2 Switch on the power supply to the indoor unit.
