Time controls

Heating Time Control

A single channel timer provides accurate time control of periods when the boiler operates. It needs to be combined with a room thermostat so that room temperatures can be monitored and the boiler switched on or off during an ‘on’ heating time. Single channel time control is usually for combi boilers or for systems where the hot water is controlled via separate controls

Heating & Hot Water Time Control

A dual channel programmer provides accurate time control of periods when the boiler needs to operates.to provide both heating and hot water. These periods can be independent of each other It needs to be combined with a room thermostat so that room temperatures can be monitored and a cylinder thermostat o monitor the temperature of the hot water. These allow the boiler to have temperature control during an ‘on’ heating time. Dual channel time control is usually for heating system with stored hot water​​​​

​​Combined Time & Temperature Control

Combined time and temperature control allows the creation of heating schedules that set variable temperature set points throughout a 24 hour period, usually providing a maximum of 6 time periods that can operate at different temperatures. Hot water time control is also included in some programmable thermostats

Temperature controls

Heating Systems

For Combi Boilers

Time and Temperature control is commonly provided by a programmable thermostat. Hot water control is not required
For Stored Hot water systems

Separate time and temperature control of both the heating and hot water is required using a combination of programmer and room and cylinder thermostats. Some programmable thermostats also provide hot water control
