Temperature settings
Set the hysteresis for heat pump on/off switching on the return sensor T1
(GT1). A lower value gives a shorter interval between start and stop. Less
than 5ºC should be avoided.
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. You can, for
example, set a maximum temperature for the fl oor heating system. 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 heater’s outer shell. Note that the
setting does not apply to the temperature inside the hot water heater. The
factory setting is 51ºC, but this temperature can be increased to max 54ºC
if necessary. Only applies when the sensor T3 (GT3) is connected.
Set the hysteresis for the hot water temperature. The function measures
below and above the value set in menu 2.3. Only applies when the sensor
T3 (GT3) is connected. Less than 4ºC should be avoided.
Clock setting of additional heat
You can set the control unit so that the additional heat 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.
Commissioning/Ser vice
Make a check of all the functions before you commission the heat pump.
You can manually start and stop the pumps and valves from the menu
Manual operation of all functions
.
Set when the additional heat should be activated. On delivery the heat
pump is set to activate the additional heat when necessary. Choose
between Yes or No. If you choose No, the additional heat only engages
during alarms, extra hot water and hot water peaks.
The function Fast restart means you do not have to wait for the normal
restart time to start the heat pump. If there is a need for heating or
hot water the heat pump starts within 20 seconds. The setting must be
repeated each time you need to make a fast restart.
