Weishaupt WTC-OB

Post by markison » 16 May 2020, 13:32

i checked the compatibily list and the wtc-ob is named there.
but if i check the electric plan, i could not find any contact to switch on/off

the boiler is connectet via a bus system wcm-fs 2.0 with an external temp-sensor for outdoor (north-side). no inside thermostate

where to connect the smart thermostate?

Vu comme cela pourquoi pas la connection H1 ou H2 ?
Seen like this, why not the H1 or H2 connection?

On page 45 of the manual, it states that terminal „H1“ supports the function „Heizkreis-Freigabe“ (engage heating). So you have to wire the Relais as follows:

The Brown and Blue wires have to be attached to the 230V supply (gray terminal) to power the Relais.
The Black and Grey wires have to be wired to the „H1“ terminal (cyan terminal), polarity is not important.

The H1 terminal should be correctly configured by default as parameter „P16 - 0“.


Braunes und blaues Kabel an den 230V Ausgang anschließen, graues und schwarzes Kabel an den H1 Eingang, Polung ist egal. Der H1 Eingang sollte standardmäßig richtig konfiguriert sein als „Heizkreis-Freigabe“
