Values of the resistance:
T = 0 °C R = 100,0 Ω
T = 20 °C R = 107,8 Ω
T = 100 °C R = 138,5 Ω
T = 200 °C R = 175,8 Ω
Fix the flue gas sensor into the flue connection
by the bayonet flange!
Do not extend the connection conductors of
the sensors!
Treat the boiler sensor and the safety
thermostat sensor by a warm-water paste, put
it into the casing and fix by a spring!
Polarity is not important.
Use the 3-wire flexi cable with the
section of 0,75 mm
