Connected extra sensors
The control unit senses which extra sensors (T3 hot water, T5 room sensors) have
been installed and displays which are acknowledged when you select Connected
extra sensors.
Manual operation
Make a check of all the functions before you commission the heating installation.
You can manually start and stop the pumps and valves from the menu Manual
Operation. Select Yes to activate.
NOTE! The function is deactivated by selecting No in Manual Operation.
Additional heat options
Additional heat only blocks the start of compressor and fan. Heating and hot water
is supplied via the additional heater.
Block additional heat blocks the additional heat function, but not during alarm
mode, hot water peak, extra hot water or operation with additional heat only.
NOTE! Normally this is not recommended.
Language
This allows you to change the language to one other than that selected when the
heat pump was fi rst started. The selected language automatically becomes the
factory setting, that is, is not changed by Return to factory settings.
Correct sensor
All sensors can be corrected here. The correction value is stated directly in °C.
Normally one should avoid correcting a sensor. The value that is given without
correction is most often the correct one. Correction of maximum 5ºC up or down
is possible.
Fan defrost interval and Fan defrost time
Because weather conditions vary from place to place some factory settings for
defrosting may need adjustment. This particularly applies to locations with high
humidity where there is a risk that the fan will ice up. Fan defrost means that
warm air is blown upwards through the fan.
The fan defrost function is active when the value Fan defrost interval is between
1 and 10, factory setting is 1. The value 1 states that fan defrosting will occur at
each ordinary defrosting. If the value is set to 3 then fan defrost occurs every third
defrost.
Select how long fan defrost should last. The factory setting is 1 min.
Min = 1 and max = 5.
The function is deactivated by selecting 0 in Fan defrost interval.
Temperature limit for fan defrost is set to -5ºC. No fan defrost occurs below this
temperature. This setting can be changed under Fan defrost in the Advanced menu.
