Product Information

Honeywell ST9100A Programmer is a single channel timer, designed primarily for control of a single heating zone or combi boiler application. It is suitable for mains, low voltage, or potential-free switching of the heating load. The Honeywell ST9100A model is a 1 day timer with two on/off switchings times per day (which can be increased to 3). The Honeywell ST9100A Programmer can be used for combi boilers, heating zones or any application where small electric loads need switching. The only time the programmer goes blank screen is when attempting to fire up heating, hot water works fine. e The search function were more Google like – if you put Bavia, Bravia or similar into the search no suggestions are forthcoming.

The Honeywell ST9100A provides timing control for your central heating system, letting you set ON and OFF periods to suit your own lifestyle. The ST9100A does not directly control the temperature but works together with other temperature controls, such as room thermostats, to control your heating system in your home. The upstairs radiators have not been warming up very well for some time, i have tried balancing/bleeding but no remedy. I thought the service was excellent and had no problems, would definitely use you again and recommend.

Why Buy From Us?

The programmer allows you to set 2 to 3 on/off period for each day, giving you added flexibility on when your heating is in operation.

All were fitted new 3 years ago with a new temperature dial, and for the last few months the heating side of things have not been working as it should. It was unfortunate that the first delivery of my item was lost in transit but full marks to myTub as they kept in helpful communication with me and sent a replacement item shortly after me reporting the non-delivery. I thoroughly recommend this company for their efficient and friendly service.All Honeywell ST9100 models incorporate the Line of Text (LoT™) display that gives clear plain English instructions whenever any button or slider is used.
