Check that the additional electric heat works and that the control from the heat pump works.
E71 E41. E1
Check that external signals and alarms to/from the heat pump work, e.g., EVU block and general alarm
Check the pressure and temperature of the collector circuit again, fill up with collector circuit fluid, if necessary
Turn on the motor cut-out for compressor 1 (top). When compressor 1 goes well (with reasonable temperature dif-
ferences), turn on the motor cut-out for compressor 2 (bottom).
When both compressors go, check that the temperatures of the heating system and the hot water heaters
increase, also make sure that the temperature differences are reasonable. Check regularly the pressure and tem-
perature differences, fill the heating system up and clean the filter, if required.
Check that connected sensors show values within permitted range:
T2 Outdoor sensor: Check that the sensor is on a north-facing wall and not above windows or ventilation openings.
The sensor must not be concealed or be flush under edge eaves
E4x.T3 Hot water sensor:
E1x.T1 Flow sensor circuit 2-4 Check that the sensor is positioned correctly (in accordance with the system dia-
gram in the handbook) with good contact
E1x.TT.T5 Room sensor circuit 1-4: Sensor placed on a representative hot junction, see instructions in handbook
Operating temperatures (after 20 minutes of operation):
Set the flows on the warm and cold side of the hot pump, respectively, by setting correct speed on the built-up cir-
culation pumps. Note: the filters must be newly cleaned when this setting should be done.
Step 1 E21 (top):
Heat transfer fluid out (T8): ________ °C Heat transfer fluid in (T9): ________ °C
Difference T8-T9: ________ K (should be 7-10 K). Setting heat carrier pump (G2): ___________________
Collector circuit in (T10): ________ °C Collector circuit out (T11): ________ °C
Difference T10-T11: ________ K (should be 2-5 K). Setting collector circuit pump (G3): ___________________
Step 2 E22 (bottom):
Heat transfer fluid out (T8): ________ °C Heat transfer fluid in (T9): ________ °C
Difference T8-T9: ________ K (should be 7-10 K). Setting heat carrier pump (G2): ___________________
Collector circuit in (T10): ________ °C Collector circuit out (T11): ________ °C
Difference T10-T11: ________ K (should be 2-5 K). Setting collector circuit pump (G3): ___________________
Check that three-way valve E21. Q21 goes over to heating operation when the temperature in the hot water heater
is up
Customer/responsible for installation: has been informed of how to operate the heat pump
Documentation handed over
Date/signature of the installation installer/person in charge of commissioning:
