T4_IBH_ON is the ambient temperature for starting the
backup heater. If the ambient temperature rises above
T4_IBH_ON, the backup heater will be unavailable. The
relationship between operation of the backup heater and
the ambient is shown in the picture below.
About OTHER HEATING SOURCE
The OTHER HEATING SOURCE is used to set whether
the backup heater, and additional heating sources like a

NOTE
t_IBH_DELAY is the time that the compressor has run
before the first backup heater turns on (if T1<T1S).
t_IBH12_DELAY is the time that the first backup heater
has run before the second backup heater turns on.
If an additional heating source is available, please select
YES at the corresponding position. Press OK and the

dT1_IBH_ON is the temperature difference between T1S
and T1 for starting the backup heater. Only when at the
T1<T1S-dT1_IBH_ON can the backup heater turn on.
When a second backup heater is installed, if the
temperature difference between T1S and T1 is larger than
dT12, the second backup heater will turn on.
The relationship between operation of the backup heater
and the temperature difference is shown in the diagram
below.
