INFORMATION
Energy data calculations of the unit will only be correct for settings of [6-03] and
[6-04] which fit the actually installed backup heater capacity. Example: For a backup
heater with nominal capacity of 6 kW, the first step (2kW) and the second step (4kW)
correctly sum up to 6 kW.
Capacity step 1

Code
Description
[9.3.4]
[6‑03]
▪
The capacity of the first step of the backup
heater at nominal voltage.
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.

Maximum capacity that should be delivered by
the backup heater.

Equilibrium
: Deactivate backup heater (and
tank heating support 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 (and tank heating support 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.
