Connecting 2 UH1's
Posted by Unknown on 26th Jul 2010
Q - If you connect 2 UH1's together, Is it possible to have 1 hw controller connecting to each UH1 but only 1 of the UH1's connected with the DHW connected. if there was demand from the other UH1 would this be relayed to the UH1 that has the DHW connected?
A - The hotwater would be controlled by the timer connected to that particular UH1 only, the signal would not be sent to other UH1's via the network link.
-
Does the UH1 provide a 12V supply?
Posted by Nick Earle on 13th Jul 2010
Q - Does the UH1 incorporate a 12 Volt powers supply unit supply power to the Network Thermostats or is it necessary to purchase a separate 12V power supply unit?
A - You would provide the UH1 with 230v to power the board, this would then give you the 12v needed to power upto 8 thermostats. There is no need for any additional 12v power supply.

Can it be used just to control radiators
Posted by Jim on 6th Apr 2010
Q: From your demonstration video I can see you have a UH1 upstairs controling the radiators. Can I have one of these just to control 8 radiator zones and not use under floor heating.
A: Yes that would work fine. In your case you wouldn't need the UFH pump or valve output.
