The Efficient Home Forum

Hi, we have just had ufh added to one of our rooms. Currently have Evohome running on all of our radiators but want to connect the UFH. The plumber has installed it as a single zone with a Polypipe PB970028 ZRU and connected a BDR91 and a single zone wall thermostat, everything is paired up but I can't help think something is missing. I connected the BDR91 to the controller as a zone valve as suggested but when I set the temperature it does not activate the pump on the ZRU, I am wondering if something is missing or the electrician has wired it incorrectly.

Any suggestions would be great,

Thanks

Mark

No need to reply, figured it out thanks to the Evohome Shop YouTube on how to wire a BDR91, it appears the electrician did not put the link wire between the second live and a terminal so the BDR91 had no power to give the pump.

Good to hear you sorted it.
