Aprašymas
It is designed to control the temperature of a solid fuel boiler by opening and closing the flap regulating the air supply to the furnace. Additionally, the device controls the operation of the circulation pump.
-Maintaining the set temperature of the boiler by controlling the air intake
-The function of supporting the combustion process, the so-called blowing
-Automatic switching off of the control after extinguishing the boiler
-The flap is lowered in the event of a power failure
-Closing the air inlet when adding fuel to the boiler
-Central heating circulation pump control
-COMFORT SYSTEM function, which protects the pump against limescale
-The function of protecting the installation against freezing and overheating of the boiler
-Signal of temperature sensor damage
-Engine lock / failure signaling
-Adjustable display brightness – increased when changing settings
-Possibility to connect the CONTROL remote control panel with an audible alarm function
