Hi all, a newbie here with relatively little experience. We have a central heating system fitted with TSV's (thermostatic valves) on all radiators. It is controlled by a Honeywell ST799 controller, which is attached to a Glow Worm Ultimate 40 FF boiler. The system has no main thermostat. I want to be able to fit Smart thermostatic radiator valves to control the heating in each room. Is the controller/system compatible? And any recommendations if it is.
