5. Make the necessary settings on the control panel.
a. Confi rm that external sensors are connected. If T3 (GT3), T4 (GT4) or T5
(GT5) have been connected, confi rm these in the control panel so the control
unit knows they are installed. The displays presented by the sensors are only
shown if the sensors have been confi rmed.
b. Set the maximum output to be used by the electric heater. Choose between
1/3, 2/3 and 3/3. It is important that the electrical installation is adapted to
handle the maximum electrical output. On delivery the control unit is set to 2/3.
For more information about this see section Technical information. Setting 1/3
provides an additional 3kW, 2/3 provides 6kW and 3/3 provides 9kW.

checking
Temperature settings
Set the hysteresis for heat pump on/off switching on the return sensor T1 (GT1).
A lower value gives a shorter range between start and stop. Less than 5ºC should
be avoided when using regular radiators. For underfl oor heating 3-4°C is recom-
mended.
Set the neutral zone for the mixing valve in a heating system with two heat curves.
In the neutral zone the mixing valve receives no signal to open or close. Only
applies when the sensor T4 (GT4) is connected.
Set the maximum temperature in the mixing valve circuit. Set a maximum tempera-
ture for the underfl oor heating system if applicable. On delivery of the heat pump
the value is 60ºC. Only applies when the sensor T4 (GT4) is connected.
Hot water settings
Set the temperature in the hot water cylinder.
Clock setting of electric heater
The control unit can be set so that the electric heater is fully blocked during certain
periods of the day. Read more under the heading Extra functions (Customer level
2)/Timer control about how to set the control unit.
