8 Configuration
Equilibrium
# Code
[9.3.6] [5-00] Equilibrium: Is backup heater operation
allowed above equilibrium temperature
during space heating operation?
▪ 1: NOT allowed
▪ 0: Allowed
[9.3.7] [5-01] Equilibrium temperature: Outdoor
temperature below which operation of
the backup heater 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
[9.3.8] [4‑00] Backup heater operation:
▪ 0: Restricted
▪ 1: Allowed
▪ 2: Only DHW Enabled for domestic hot
water, disable for space heating
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.
# Code
[9.4.1] [6‑02] Capacity [kW]. Only applies to domestic
hot water tank with an internal booster
heater. The capacity of the booster
heater at nominal voltage.
Range: 0~10 kW
BSH allowance schedule
Program when the booster heater can operate. You can set a
schedule for the booster heater here using the schedule screen. Two
actions per day are allowed in a week schedule. For more
information, see "8.3.8 Schedule screen: Example" on
Example: Only allow the booster heater to operate during the night.

BSH eco timer
# Code
[9.4.3] [8-03] Booster heater delay timer.
Start-up delay time for the booster heater
when domestic hot water mode is active.
▪ When domestic hot water mode is
NOT
20 minutes.
▪ The delay time starts from booster
heater ON temperature.
▪ By adapting the booster heater delay
time versus the maximum running
time, you can find an optimal balance
between the energy efficiency and the
heat up time.
▪ If the booster heater delay time is set
too high, it might take a long time
before the domestic hot water reaches
its set temperature.
▪ The setting [8‑03] is only meaningful if
setting [4‑03]=1. Setting [4‑03]=0/2/3/4
limits the booster heater automatically
in relation to heat pump operation time
in domestic water heating mode.
▪ Make sure that [8‑03] is always in
relation with the maximum running
time [8‑01].
Range: 20~95 minutes
Operation
# Code
[9.4.4] [4-03] Defines the operation permission of the
booster heater depending on ambient,
domestic hot water temperature or
operation mode of heat pump. This
setting is only applicable in reheat mode
for applications with separate domestic
hot water tank. When setting
[4‑03]=1/2/3/4, the booster heater
operation can still be restricted by the
booster heater allowance schedule.
