Backup heater control
Electric heating coil downward control
Heat pump 0 = 5 min.;
1 = 10 min.; 2 = 15 min.; 3 = 20 min.
33 - 0-3 1
Upward and downward control of the backup heater
stages based on the difference between the set
temperature defined on the remote control and
the supply water temperature downstream of the
backup heater (THO sensor)
Electric heating coil upward control
Heat pump 0 = 10 min.; 1 = 20 min.
2 = 30 min.; 3 = 40 min.

Outdoor temperature from which the backup heater
is no longer switched on (measured at the TO
sensor)
0= 0K 2= 20K 4= 40K

B9 - 0-4 0
Temperature difference between TSC-F (target
heating value, e.g., Zone 1 +40°C) - THO
(Sensor downstream of backup heater, e.g.,
+10°C) = 30 K (if, e.g., B9 = 3 is set, the backup
heater would switch on at 3 kW at +10°C THO
temperature.)
Capacity of the backup heater
0 = 3 kW
1 = 6 kW
2 = 9 kW

Night setback (do not
use with FBH)
Night setback temperature 26 - 3-20°C 5 Kelvin by which the temperature is reduced
Zone selection 0= Zone 1&2; 1= Zone 1 58 - C0~1 0 Zones in which the temperature is reduced
Start time - OE 0~23 22 Time at which the night setback begins
End time - OF 0~23 6 Time at which the night setback ends
Percentage method
Auto curve in ZONE 2 controls 80% (FC31) of Zone 1.
The water temperature setting does not drop below 20°C.
Set temperature in ZONE2 for A‘ °C at an outdoor tempera-
ture of T0°C, B‘ °C at T1°C, E‘ °C at 20°C
