Temperature control
• The control can be used to pre-set an interior temperature. According to the size of heating space and
prevailing outdoor temperature, the heater’s temperature can be set within the range of +10 °C to +30 °C.
Control in the heating mode
• During the heating mode, the room temperature or the temperature of the sucked in heating air is constantly
measured. Based on these and the pre-set temperature by controller switch, heater’s working condition will be
adjusted. If the temperature is higher than the temperature selected on the control element, the heater starts
to regulate its output.
• There are 4 control stages so that the outflow of heat produced by the heater can be adjusted finely to the
heating requirements. Fan speed and fuel quantity correspond to the control stage.
