– HEAT PUMP
Crank temp
: measured crankcase temperature
Set
: crankcase heater startup temperature
DiffLeft
: crankcase heater starts up when the crank-
case temperature is lower than Set-DiffLeft
DiffRight
: the crankcase heater turns off when the
crankcase temperature is above Set+DiffRight and
the set time has passed
Post time
: time that determines how long the crank-
case heater should remain on after the Set+DiffRight
value is exceeded.
Crank Heater Power
: current status of the crankcase
heater
Procedure counter
: number of completed crankcase
heating cycles
Countdown
: remaining time until the end of the
crankcase heating procedure
Set Time
: duration of crankcase heating minicycle
Step Count
: number of minicycles constituting one
crankcase heating cycle
Off Min Reset
: maximum time of the heat pump dis-
connected from power that will not reset the number
of finished crankcase heating minicycles
Off Hours
: the minimum time of the heat pump dis-
connected from power that will make crankcase
heating start when power returns.
Tray Heater mode
: on/off/automatic operation of tray
heater
Temp. treshold
: ambient temperature below which
the condensate tray heater will turn on
Tray Heater status
: current state of the heater
Pre delay time
: time of condensate tray heater activa-
tion before evaporator defrosting countdown begins
Post delay time
: time to turn on the condensate
heater after the countdown to evaporator defrosting
is complete
Initial warmup
: activation of the initial water heating
mode in CH mode.
Temp set
: set value of water temperature in CH mode
to be heated by the heater
Temperature
: current value of buffer/supply water
temperature
Pump state
: the control value exposed to the circu-
lating pump expressed as a percentage
Heater state
: on/off
Water flow
: volumetric water flow value
