diagnosis.

Heat Pump

LINE FUNCTION
8402 Electric immersion heater 1 flow
8403 Electric immersion heater 2 flow
8406 Condenser pump
These lines are used to check the operating mode
of the components controlled by the heat pump
relays. The display "0" means that the associated
components are currently disconnected. The
display "1" means that the associated components
are currently switched on.
Setpoints and Measured Values
LINE FUNCTION
8410 Return temp HP
8412 Flow temp HP
8413 Compressor modulation
8414 Modulation electric flow
8425 Temp differential condenser
These lines allow the various setpoints and
measured values for the heat pump to be viewed.
Hour / Startup Counter
LINE FUNCTION
8454 Locking time HP
8455 Counter number of locks HP
8456 Hours run electric flow
8457 Start counter electric flow
Locking time HP
Displays the cumulative locking time since start-
up by the electrical services (via external locking
signal).
Counter number of locks HP
Displays the cumulative locks since start-up by the
electrical services (via external locking signal).
Information:
This information applies to relays defined as
normally open contacts. For normally closed
contacts, the action is reversed.
Hours run electric flow, Start counter
electric flow
These lines are used to view the hours of operation
and the number of start-up of electric heater.
