Temperature sensor 
Terminal 1: Flue gas sensor F1 Pt100  Mount the flue gas sensor into the flue gas connection by  the 
bayonet flange!
Terminal 2: Flue gas sensor F1 Pt100
Terminal 3: Boiler sensor F2 Pt100  Do not extend connection conductor´s of sensors!!!
Terminal 4: Boiler sensor F2 Pt100

Values of resistance:
Boiler sensor and sensor of safety thermostat have to be 
treated with warmwater paste, put into gasket and tighten by 
holding spring!
Polarity is irrelevant
Air flapV1 – V2, circuiting pump, suction fan 
For connection of circuiting pump and 
suction fan, use 3-conductor flexicord 
with conductor´s cross section of 
0,75mm2!
