Hi, I have a conventional Greenstar 18ri in a house I rent out. Can anyone explain to me in simple terms the function of the CH control knob on the front of the boiler?
When it was installed, the engineer set the knob at about three quarters way round to the right and said that was about the usual setting, and normally there is no need to touch.......something to do with speed of the flow or the temperature of hot water to the radiators.
Last time I visited I noticed the house was very warm. The girls there have the normal thermostat control in the hall at about 22c or 23c, and also keep on turning the thermo controlled valves on the radiators to max which is annoying. Consequently it gets like a sauna !
If I turned the control knob on the boiler slightly back anti-clockwise, would this have the effect of reducing the temperature of the radiators at all? I may have this wrong, but I am wondering if the hall thermostat clicks off when the 22c temperature is reached but because the radiators are so hot, the temperature still rises for a while afterwards? Also, does the boiler stay on longer, the more the CH knob is turned clockwise?
