Commissioning checklist/Check off measures carried out
Chapter
1. Supply indoor unit and outdoor unit (if present) with voltage These instructions Chap. 4.7
2. Enter "Expert code" RoCon+ 4.5.1
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!
RoCon+ 5.2
4. Activate the ventilation function RoCon+ 4.5.7
▪ Check the water pressure
These instructions Chap. 5.1.3
▪ Checking the minimum flow
Chap. 5.1.4
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.
RoCon+ 4.1
6.
Commissioning is complete when a DHW temperature of more than
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).
RoCon+ 4.5.7
5.2 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. 7.2.2).
▪ The storage tank is filled up to the overflow (seeChap. 7.2.1).
5.2.2 Start-up
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.
