CONTROL UNIT

The control unit controls and monitors the heating and hot water 
production with the heat pump and additional heat. The monitoring 
function shuts down the heat pump in the event of a fault so as to prevent 
damage to critical parts of the pump.

7.1

ADDITIONAL HEAT 

The additional heat becomes active in the event of emergency operation, 
extra hot water and hot water peak.

The additional heat is provided through electric additional heat.

The Multi module accessory is required for mixed additional heat.

The control unit will automatically activate the additional heat, when 
needed.

7.2

HOT WATER PRODUCTION

Hot water is heated in the domestic hot water cylinder and the control 
unit gives priority to hot water before production of heating water 
according to the settings that are made. The domestic hot water cylinder 
is fitted with a sensor that senses the temperature of the domestic hot 
water.

CONTROL PANEL

Settings for the control of the heat pump are made with the control unit's
