## Description

Programmers allow you to set ‘On’ and ‘Off’ time periods. In general 1 channel timeswitches only control heating (for combi boilers especially). 2 channel models control both heating and stored hot water and allow them to go on and off at different times.On some programmers you must also set whether you want the heating and hot water to run continuously, run under the chosen ‘On’ and ‘Off’ heating periods, or be permanently off. The time on the programmer must be correct. All of these products switch between Greenwich Mean Time and British Summer Time automatically.You may be able to temporarily adjust the heating programmer, for example, ‘Override’. The heating will not work if the room thermostat has switched the heating off. And, if you have a hot-water cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature.The THR850SUK 1 Channel Timeswitch provides accurate time control for central heating systems and other applications. Single Channel Timeswitch allows you to set ‘On’ and ‘Off’ time periods. Single channel timers are typically used to switch central heating or hot water, but not both. If you require both please choose a 2 channel programmer. THR850SUK is suitable for replacing a wide range of timers on the market, and is a direct replacement for Honeywell ST6100 Timers without the need for re-wiring. Features include: 7 Day Programmable timeswitch can program each day differently, up to 3 periods per day. The straight forward Backlit Display makes viewing easy, even in dimly lit rooms and hallways. Simple function buttons keep operation and programmable simple. - LoT ( Line of Text) Display Technology ensures simplified programming and operation. Battery and super capacitor provide twin backup to retain date/time during loss of power and the summer/winter time change is automatic so you don’t have to remember to do it.
