Honeywell ST9100A1008 24 Hour Single Channel Time Switch
The Honeywell ST9100A is a single channel timer, designed primarily for control of a single central heating zone or combi boiler application. It is suitable for mains, low voltage, or potential-free switching of the central heating load. This model is a 1 day timer with two on/off switching times per day (which can be increased to 3). It can be used for combi boilers, central heating zones or any application where small electric loads need switching.

The Honeywell ST9100A incorporates 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 the timer reliably, without needing to find an instruction manual.
