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

and

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

button to enable

the schedule timer again.

For EKHBRD*AB/AC
