Heating Controls

[DaleRCL]

Hello, I am working in a flat with communal heating from a large boiler which does the whole block. I currently have 22mm flow and returns in the flat I'm in with isolators so I can work off of them.
The customers wants a programmable room stat to set on/off times and obviously gauge the temperature.
I have asked the electricians on site, if I cut in a Honeywell zone valve on the flow will they fit a prog room stat to open and close it accordingly. They have said this is no problem if I can provide them with a wiring diagram.
Does anyone know, firstly, if what I have suggested is possible and if so, where might I find a wiring diagram for such a set up.
Forgot to mention, the boiler will be on constant so I will only need the stat to open and close the zone valve, not fire boiler, run pump etc.

Thanks

I really dont think you should do this without consulting whoever manages your heating system. This system is known as district heating and some (not all) run at much higher pressures some up to 6 Bar you really should not cut into such a system without knowing all the ins and outs of it.

I'm not cutting into it. I will be putting the zone valve after the isolators I am working from. And the system is owned by my customer (they own and pay the bills for the whole block if flats)

Tell them a wiring diagram will be included with
a) the valve
b) the stat

yes its possible and really easy to achieve

what sort of valve are you planning on using
2 port?
3 port?

Just one two port valve, I only have one heating zone, no cylinder coil or second zone. Do the wiring diagrams which come with the valve and programmer not have the boiler in the equation? This is the bit I'm unsure of.

2-port valve wire call from stat/timer to brown on valve
