Detailed
description
[6-02] Heater kit
Once installed, you can activate the heater kit by changing field setting [6-02]=1. From that moment
on, the heat pump system will take the heater kit into account whilst deciding operation. When the
heater is actually operating, the heater symbol
(
is shown on the remote controller. There is no step
1-2 indication.
Use of backup heater with EKHBRD*AA*
(*) Auxilary relay (following heat pump tariff signal) can be applied to switch off BUH during HP
tariff operation
Use of backup heater with EKHBRD*AB*/EKHVMY(R)D*AA*
(*) Auxilary relay (following heat pump tariff signal) can be applied to switch off BUH during HP
tariff operation
Note
Setting [8-01]:
Not for EKHBRD*AA*: was used to set auto restart on or off. This has been changed to default on.
[8-02] Emergency operation
During emergency mode, heating is only done by the heater kit, not by the heat pump. Activation of
emergency mode is done by changing field setting [8-02]=1. Activating the emergency mode will
stop the heat pump operation. The pump of the indoor unit will be started, but heating itself is done by
the heater kit. If there are no error conditions in leaving or returning water thermistors, the heater kit
can start to follow emergency operation.
Note
Before activating emergency operation, be sure to activate the heater kit. The heater will stay in
emergency mode until the field setting is set back to default [8-02]=0.
Benefit kWh rate power supply mode
Note
This concerns the benefit kWh rate power supply mode of the EKHBRD/EKHVM indoor unit. For
more details, refer to the "Field settings" chapter of the indoor unit installation manual.
If the benefit kWh rate power supply is used for the indoor unit, the indoor unit will go into
emergency operation automatically when the power supply is interrupted.
