PERATION OF THE UNIT
The remote controller offers full control over your installation. It can
control all heating applications which vary in capacity, electrical
supply and installed equipment (options). Operating the HXHD125
unit comes down to operating the remote controller.
INFORMATION
It is advised to use the remote controller, which includes
room thermostat function, delivered with the unit.
This will prevent excessive space heating and will stop the
outdoor and indoor unit when the room temperature is
above the thermostat set point. Based on the request from
the user there is an immediate feedback to the compressor
control which optimizes the performance.
Refer to the typical application examples in the indoor
installation manual for more details.
WARNING
■
Never let the remote controller get wet. This may
cause an electric shock or fire.
■
Never press the buttons of the remote controller with a
hard, pointed object. This may damage the remote
controller.
■
Never inspect or service the remote controller
yourself, ask a qualified service person to do this.
■
Do not rinse the indoor unit. This may cause electric
shock or fire.
■
Do not climb, sit or stand on top of the unit.
■
Do not place any objects or equipment on the unit top
plate.
