Honeywell ST9400A 1 Day Two Channel Programmer
Honeywell ST9400A Programmer is a 2 channel programmer, 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 ST9400A 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 ST6400A Programmer can be used for combi boilers, heating zones or any application where small electric loads need switching.
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.
