Hello. I've purchased a Hive 2 heating and hot water system (self install) to replace my Hortsmann H27XL and Hortsmann HRT4-B thermostat. I live in a new house with two zones for controlling upstairs and downstairs heating, with separate hot water control via three separate motorized valves. The boiler is a Potterton Promax 24 System with a megaflow hot water cylinder upstairs and a frost sensor. For now I'm only installing Hive on Zone 1 with the intention to add Hive multi zone at a later date (if this is at all possible).
What I'm not sure about is what to do with the wires for the old thermostat on Zone 1? It appears that the wires control the motorised valve, so if I connect them together the valve will be permanently open, or closed if the wires are not connected. Shouldn't Hive be controlling the state of Zone 1's valve as before?
Secondly the dual channel receiver will replace the H27XL, if during the heating ON schedule Zone 1 reaches its temperature, would Hive switch off the boiler thus effectively preventing Zone 2 from heating any further if required?
I've included pics of the wiring for the thermostat and programmer along with my current Hive wiring setup (the grey wire is not used).
