Tr: 14.0°C Verd.: 1
Tb:-04.4°C MV-FL: 1
Tu: 34.4°C MV-HG: 0
Tm 34.4°C MV-LU: 1
Tr
Current room temperature measured by the sensor on the control unit or
an external room sensor
Tb
Temperature on the heat pump evaporator register
Tu
Current temperature in the lower area of the boiler. Depending on this
temperature, the heat pump is activated.
Tm
Current temperature in the middle area (centre) of the boiler. Depending
on this temperature, the domestic water heating can be given priority and
the room heating can be temporarily disabled by the heat pump.
Verd.
Current status of the compressor or the heat pump
MV-FL
Current status of the liquid line's solenoid valve. This valve is only closed
at the start of thawing; it otherwise opens when the compressor operation
starts.
MV-HG
Current status of the hot gas line's solenoid valve. It is open during the
compressor's start phase (unloaded start) and during the thaw process.
MV-LU
Current status of the air capacitor line's solenoid valve. Air heating is ena-
bled when this valve is open.
