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.
Ventilating mode
• Press the ventilation button. Heater will work in ventilation mode. Changeover in mode of ventilation and burning can
be initiated at any time.
Switching off
• Press the stop working button. Heater switches off, metering pump stops working, and glow plug is switched on for
approx. 40 seconds. After fan runs on for approx. 4 minutes to cool down, heater is shut down when indicating light
goes out.
