2-1.1 Boiler Thermostat Control
The Boiler Thermostat Control is used to control the temperature of the water within the
Boiler Water Chamber.
The heat sensor phial of the Thermostat is on the end of a capillary tube and placed in
one of the tubes on top of the Boiler waterway.
The Thermostat control has a ‘STOP’ position to switch the Boiler OFF.
The temperature range of the control is 55°C to 90°C.
The recommended settings of the Boiler Thermostat control are:-
1.
Winter Heating and Hot Water 80°C.
2.
Summer Hot Water only
65°C.
A setting below 60°C can, on some heating systems, induce corrosion and reduce the life
of the Boiler.
