[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
pla
ced 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
depend
ent
(automatic). The temperature range is between 25°C and 80°C and can be set by
ébi and ébj 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
automatic
a
lly 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
s
ettings 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 pu
mp 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 amb
i
ent 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] Emerge
nc
y 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 he
ati
ng 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.
