BSH eco timer
# Code Description
[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 active,
the delay time is 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 Description
[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.
