Connect to WEM Master PL

Post by knielen » 26 Feb 2020, 14:50

Hi,

Anyone knows if it is possible to connect to a WEM Master PL 12612? The old thermostat has 3 wires, 230V N L and L(switched). So I'm one wire short for the Thermostat, is it a solution to bridge the L to the COMM connection?

Regards,
Kay

You can isolate N, put it aside and connect L and L(switched) to the Thermostat.
If you want to wire the Relais instead you have to connect the blue wire to N, brown to L, black to L as well and grey to L(switched).
