My current system does not have a room thermostat, and relies totally on radiator thermostats. I believe this may be wasteful as, even if all rad stats shut the respective radiators off, the hot water is still circulating around the system with associated losses. So I want to fit a room thermostat in our lounge. Is it as simple as buying the thermostat and connecting it to a suitable set of terminals in the central heating controller?
If so, my existing controller does not have any terminals for a thermostat, only terminals for the hot water and the heating. I presume there are simply dry contcts to the respective pumps, or something of the kind.
In order to connect a thermostat, do I simply need to get a new controller that has terminals for connecting a thermostat? Or is thermostat connection not as simple as that?
As Plumbob says, to add a room stat is reletively easy, as you say you have a dual programmer for heating and hot water.
It requires a 3core and earth cable between programmer and stat. position, or to local receiver near programmer if using wire free radio stat.
whichever area you fit stat the existing TRV must be removed from rads in the area. It is usual to do this in a hallway rather than lounge.
Basically the out going wire from programmer is interupted by stat contacts, it's easy when you know how!!!
