The Charnwood central heating control system is a pre-wired kit suitable for use with all multi-fuel room heaters, cookers and boilers with a water temperature sensing thermostat. The system gives a fully automatic timed control with built in safety features for your central heating system, resulting in significant fuel savings. A high-level pipe thermostat prevents the system boiling by bringing on the pump if the pre-set temperature is reached.
The low-limit thermostat cuts out the pump if the water temperature in the boiler falls below the pre-set limit, cutting down boiler condensation and increasing its life span. The system is completely pre-wired (with exception of the pump cable) comprising of a digital timer, two pipe thermostats, a convenient wiring centre, a cable for the pump and a 13amp plug.
