Closed-loop operation
The temperature sensor integrated in the controller board (3) continuously measures the temperature of the drawn-in interior air and compares the measured value with the timer (14) specified value.
Control "LOW" - "MEDIUM" - "LOW":
The heater switches to the "LOW" control setting when the interior temperature exceeds the set temperature. The combustion air and heater blowers (4) run at their slowest speed. The fuel metering pump (13) is run at the slowest clock frequency
If the interior temperature drops below the specified temperature, the heater switches to the "Medium" control setting.
"LOW" - "MEDIUM" - "LOW" control usually covers all heating requirements.
If the heating requirement exceeds the heat provided by the "MEDIUM" setting, the heater switches to the "POWER" control setting.
If the heating requirement is less than the heat provided by the "LOW" setting, the heater switches to the "OFF" control setting.
Control interval
After the regulated heater power-down mode, constant ventilation at the lowest blower speed setting takes place.
If the interior temperature drops below the specified value a new starting procedure takes place.
The restart takes place at the "MEDIUM" control setting.
