Functional Description
In Normal mode the unit strives to maintain the
set temperature. When the outdoor temperature
approaches zero it starts the heater to go in
and supplement heat to maintain comfort. The
heater turns off when the temperature are 2
degrees below than the set temperature.
In Eco mode, the heater works in the same way,
but with a limit on the heater which is 3 degrees
below than the set temperature.
When the cool mode is selected the unit strives
to maintain the set temperature minus the set
value (parameter 9 on page 21). The heat ex-
changer enters the cooling recovery if the tem-
perature is colder than the outside temperature.
In operating mode, Cool stops the heat function
and activates the control signal for the cooling
coil and pump control.
