Additional capacity step 2
# Code Description
[9.3.5] [6‑04] ▪ The capacity difference between the second
and first step of the backup heater at nominal
voltage. Nominal value depends on backup
heater configuration.
Equilibrium
# Code Description
[9.3.6] [5-00] Equilibrium : Deactivate backup heater (or
external backup heat source in case of a bivalent
system) above the equilibrium temperature for
space heating?
▪ 0: No
▪ 1: Yes
[9.3.7] [5-01] Equilibrium temperature : Outdoor
temperature below which operation of the
backup heater (or external backup heat source in
case of a bivalent system) is allowed.
Range: –15°C~35°C
INFORMATION
Above 10°C ambient temperature, the heat pump will operate until 55°C. Configuring
a higher setpoint with an ambient temperature that is higher than the set
equilibrium temperature will prevent the backup heater from assisting. The backup
heater will ONLY assist if you increase the equilibrium temperature [5‑01] to the
required ambient temperature you need to reach the higher setpoint.
Operation
# Code Description
[9.3.8] [4‑00] Backup heater operation:
▪ 0: Restricted
▪ 1: Allowed
▪ 2: Only DHW : Backup heater operation is
enabled for domestic hot water and disabled
for space heating.
INFORMATION
When heating of the DHW by the heat pump is too slow, it may affect a comfortable
operation of the space heating/cooling circuit. If so, allow the backup heater to assist
during DHW operation by setting [4-00]=1 or 2.
Booster heater
Booster heater capacity
The capacity of the booster heater must be set for the energy metering and/or
power consumption control feature to work properly. When measuring the
resistance value of the booster heater, you can set the exact heater capacity and
this will lead to more accurate energy data.
