Post by zenzfamily »

I just added the Netatmao Thermostat three weeks ago . My system junkers cerapur witch the FW100 remote , aleady working . I am not able to reduce the temerature under 23 degrees . I tried all programs , reduced the temperature on the boiler , nothing helps . Do i have to connect the junkers remote again and reset all Programs on default ? Any other suggestions on working configuartions ?

At first i fixed The wires as they were at my working system . I was very happy . Everything seemed to work properly . After a short time the heating rose up very high . Even the changing of the polarity was not efficient .

OK, but the FW100 doesn't work like our Thermostat, the connections of the control wires have to be changed on the boiler. Did you do that change?
Please send us a picture of the wiring terminal, we'll tell you which ports have to be used.

OK, and on which ports of the boiler these two control wires are connected?

Sometimes I check the forum on the week-end, but I think it will be hard for me this week-end (family meeting...).
