Honeywell ST9100A 24 Hour Single Channel Timer

The Honeywell ST9100A 24 Hour Single Channel Timer is designed primarily to control a single heating zone or combi boiler. The ST9100A is suitable for mains, low voltage or potential free-switching of the heating load. The ST9100A 24 Hour Timer has two on/off switching times per day allowing the user to set 2 different times in the day, which will be the same for each day of the week, to control the domestic central heating. The ST9100A can be used for combi boilers, heating zones or any application where small electric loads need switching.

The Honeywell ST9100A incorporates a user friendly clear Line of Text display that provides clear plain English instructions whenever any buttons or sliders are used, meaning that users can reliably use the timer without having to find the manual. Also the ST9100A 24 Hour Single Channel Timer model has superseded the ST6100A which is no longer available.
