Check the direction of rotation of the fan (marked by an arrow on the outside of the fan housing). If
the direction does not correspond to the direction indicated by the arrow, the two phases of the
current connection must be reversed.
3.1 Winter operation
In the following paragraphs about “Winter operation” and “Summer operation” references are made
to the illustration of the control panel above.
¾ Set the burner switch (5) on pos. ”I” on the control panel.
If a room thermostat is connected to the WA 45 - 300 units, it automatically controls the burner. This
means that the burner will start automatically when the room temperature is lower than the
thermostat setting, and it will stop again when the temperature has reached the value set.
¾ The fan switch (4) is set on either ”AUT” or ”MAN”.
If the fan is set on ”AUT”, the fan operation is controlled as described in section 1. Function.
If the fan switch is set on ”MAN”, the fan will run continuously until it is set on “AUT”.
3.2 Summer operation
The burner switch (5) is set on ”0” and the fan switch (4) on “MAN”. This will turn on the ventilation
function and thus create a comfortable summer temperature.
