The Honeywell ST9400C 7 Day Twin Channel Programmer is designed for control of both heating and stored hot water in complete systems. The heating and hot water programmes are completely independent, to allow the system to be operated in the most energy efficient manner possible.
The Honeywell ST9400C 7 Day Twin Channel Programmer unit is a 1 day full programmer with two on/off switching times per day (which can be increased to 3). The Honeywell ST9400C Programmer can be used for combi boilers, heating zones or any application where small electric loads need switching.
Honeywell ST9400C 7 Day Twin Channel Programmer can also be set as a mini programmer for older gravity circulation stored hot water systems, where there is no interlocking control valve.
All Honeywell ST9400 models incorporate the Line of Text (LoT™) display that gives clear plain English instructions whenever any button or slider is used. This means that installers, customers and users can operate all of the controls reliably, without needing to find an instruction manual.
