Typical, I cant now get the actuator valve to open. Before, when I raised the temperature on the wireless thermostat so that it calls for heat, the actuator valve would open, the flow would start, the pump would fire and then after a few minutes the valve would close and the pump would switch...

Thanks SimonH2 There is flow through the UFH manifold and it does kick the pump into life. I'll time it tonight and see how long it takes before the valve is closed to see if it is an exact time or if not what the range of times are.

Turning the boiler stat down to 3 didn't fix the problem I'm afraid, presumably it's not the manifold stat that faulty. Sorry I dont know how to link out the Salus stat, there isnt a manual on or off switch to the UFH? It seems to be working ok though, when I increase the temp on the stat it...

Thanks for the comments Yes there is a stat on the UFH manifold to control the temp of the flow going into the system, I've set this on max. I think you are on the right lines, the stat maybe switching the system down because it is getting to hot. i'll try turning the temp down on the...

My wet UHF system has recently stopped working properly. the boiler is a Worcester 30CDi which connects to the UFH system via a Horstmann motorised valve. the manifold has a mixing thermostatic valve and a Grundos UPS 25-60 pump. everything has been working perfectly for about 12 months until 2...
