Hot water control
A cylinder thermostat like the HTS3 or Digistat+C RF and MiStat Cylinder Thermostat controls the heat supply from the boiler to the hot water cylinder. A cylinder thermostat will only be required if you have separate hot water system, if you have a combination boiler you won’t need cylinder thermostat.
How does the cylinder thermostat work?
A cylinder thermostat senses the temperature of the water inside the hot water tank. It switches on the water heating when the temperature falls below the thermostat setting, and switches the water heating off once the required temperature has been reached. The cylinder thermostat should be set between 60°C and 65°C.
The water heating will not work if a time switch or programmer has switched it off. The cylinder thermostat may not always switch the boiler off when it reaches temperature because the boiler may also be required to heat the radiators.
