8.2 Operational data
The operational data can be seen in the heat pump menu:
Operational data Description
02-053 Status heat generator
0 = Switched off
Heat pump switched off
1 = Heating mode
Heat pump in heating or hot water operation
2 = Lead time heating mode
3 = Externally blocked
Utility switch off (EVU contact)
4 = Cooling mode
Heat pump in cooling operation
5 = Lead time cooling mode
6 = Lead time de-icing mode
7 = De-icing mode
9 = Drain off
The heat pump is in draining mode after de-icing
10 = De-icing blocking time
De-icing criteria fulfilled, de-icing blocking period not yet over.
11 = De-icing pre heat
12 = De-icing 1
13 = De-icing 2
14 = De-icing 3
15 = Alarm
see Section 16.1 ALARM
16 = Malfunction
see Section 16.3 ERROR
17 = Blocked
see Section 16.6 BLOCKING
21 = TWVmax switch-off
Flow temperature too high or too low
22 = TWVset switch-off
Switching hysteresis in heat pump manual operation exceeded
23 = TQEmax switch-off
Heat source input temperature too high
24 = TQAmin switch-off
Heat source outlet temperature to low (frost protection)
26 = Bivalent switch-off
Blocking due to bivalence temperature
28 = Minimum off time
Demand for heat, but stand-still period active
29 = Minimum run time
No more heat demand, minimum running time active
36 = Passive cooling
Only possible for heat pumps with heat source water or brine.
The carrier temperature for cooling is called on without switching
on the compressor.
37 = Heating mode requested
Heat pump waits for report heating
38 = Cooling mode requested
Heat pump waits for report cooling
00-007 TWV temperature (flow
Heat pump flow temperature (sensor TWV)
ESC
