is signaled by pulse lighting the Manual Work diode. This function is made
available in order to safe operating the boiler by the user. When the ventilator is
on, you mustn't open the hearth's door.
Automatic controlling the revolutions it is the function which allows safe
operating the boiler, that is every turning the ventilator on is started from the third
gear and the speed is increasing or decreasing gradually depending on settings of
the ventilator's speed.
Attention! Every turning the ventilator on starts from 3 regardless of settings
Controlling the central heating pump
Depending on the temperature on the boiler the central heating pump switches on and
switches off. Switching on happens after reaching 35°C. Above this temperature, the pump is
working without any break. Switching off happens below 33°C. It prevents redundant pump work.
Protection
In order to ensure safe operation, the regulator has a number of protections. Every
mistake error is displayed on the LED display.
E4 – when the temperature exceeds the maximal temperature of the boiler
(set to 85°C)
E5 – when the temperature sensor is damaged
In both cases the air-blow turns off and the central heating pump turns on (in
the case of not being switched on). In the case of occurring the error E4, after
falling the temperature to safe level, the alarm can be deleted with the Options
key.
Besides, the controller is protected by the bimetallic mini sensor which disconnects ventilator’s
supply in the case of exceeding the temperature 90°C
