Figure 3-7.26: OTHER HEATING SOURCE menu

In OTHER HEATING SOURCE the following parameters should be set. Backup electric heater is optional.

dT1_IBH_ON sets the temperature difference between the heat pump’s leaving water set temperature (T1S) and the heat

pump’s leaving water temperature (T1) above which the backup electric heater heating element(s) are on. When T1S - T1 ≥

dT1_IBH_ON the backup electric heater is on (on models where the backup electric heater has a simple on/off control

function).

t_IBH_DELAY sets the delay between the compressor starting and the backup electric heater being turned on.

T4_IBH_ON sets the ambient temperature below which the

backup electric heater is used. If the ambient temperature is

above T4_IBH_ON, the backup electric heater is not used. The

relationship between operation of the backup heater and the

ambient is shown in Figure 3-7.22.

dT1_ASH_ON sets the temperature difference between the heat pump’s leaving water set temperature (T1S) and the heat

pump’s leaving water temperature (T1) above which the additional heating source is on. When T1S - T1 ≥ dT1_AHS_ON the

additional heating source is on.

t_ASH_DELAY sets the delay between the compressor starting and the additional heating source being turned on.

T4_AHS_ON sets the ambient temperature below which the additional heating source is used. If the ambient temperature

is above T4_ASH_ON, the additional heating source is not used. The relationship between operation of the additional

heating source and the ambient is shown in the picture below.

IBH LOCATE means IBH is installed for pipe heating.

P_IBH1, P_IBH2 set heating capacity of IBH and P_TBH sets heating capacity of TBH, which are used for energy

consumption statistics.
