104 Test Operation
[8] Option setup
[8-00] Remote controller temperature control - leaving water control
When using the remote control delivered with the unit, 2 types of temperature control are possible.
Default [8-00]
= 1 which means that the remote controller is used as room thermostat, so the remote
controller can be placed in the living room to control the room temperature. Set [8-00] to
0 to use the
unit in leaving water temperature control.
Notes : 1. In leaving water control: the heating will be activated as required by the water temperature set point.
The set point can be set manually, through the schedule timer or weather dependent (automatic). The
temperature range is between 25°C and 80°C and can be set by
bi and bj buttons.
2. Leaving water control is not allowed when multi set point control according pattern B is used.
[8-01]
For EKHBRD*AA: [8-01] Auto restart. For EKHBRD*AB/AC auto restart can not be disabled.
When a power failure occurred and the power returns to the unit, the system will automatically restore
it's settings and restart. This is the default setting [8-01]
= 1. To disable this auto restart function, set
[8-01] to
0.
Note :
When power returns after a power supply failure, the auto restart function reapplies the remote
controller settings at the time of the power supply failure. It is therefore recommended to leave the
auto restart function enabled. Note that with the function disabled the schedule timer will not be
activated when power returns to the unit after a power supply failure. Press the pr button to enable
the schedule timer again.
For EKHBRD*AB/AC: [8-01] Backup heater optional setting
[8-01]=0 (default)
During benefit kWh rate power supply mode the backup heater will not operate. No autmatic heat
pump operation stop is performed at lower ambient temperatures.
[8-01]=1
During benefit kWh rate power supply mode the backup heater will operate automatically in
emergency mode. If the ambient temperatures is lower than -25°C, the heat pump operation will
stop and the unit will atumatically change to emergency operation.
For more information about the backup heater, refer to “Part 9 - External Backup Heater Kit” on
page 255.
[8-02] Emergency mode
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 heaeter kit. If there are no error conditions in leaving or
returning water thermistor, the heater kit can start to follow emergency ooperation.
Note : Before activating emergency operation, be sure to activate theat hetaer kit. The heater will stay in
emergency mode unit the field setting is set back to default [8-02]=0.
