This controller is for fireplace. But for my is better than any controller with fan speed control.
With controllers with fan speed control you lose chimney draught. Now i've got stable chimney draught and perfect gas temperature control.

Zitat von Zalfen

hi androutso,

the temperature at which the fan switches off? My control is activated with 90° off the fan and the gasification process is disturbed.

Greetings Dirk

For control the fan. I use the original boiler thermostat. I set the boiler thermosta at 95c max. More than 95c the fan switches off.
