Honeywell ST9500C 7 Day Twin Zone Programmer

ST9500C is a 2 channel 7 day full programmer designed to control 2 heating zones. Zoning a house not only helps make the heating system more energy efficient, but can also improve comfort conditions, as each zone will only be heated when required.

This programmer gives great flexibility offering up to three on/off switchings per day, additionally each day can be programmed differently. Ideal for when the user has different heating needs from day to day. ST9500C can be set to 5/2 day or 1 day programme during installation.

All ST9000 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.

ST9500C also features a 'Holiday' button allowing the user to switch off their heating for a specified number of days (1 to 99) while they are away from home.

Building Regulations strongly recommend zoning for most houses, and mandate it for certain larger properties, so the Honeywell ST9500C can be used as an aid to compliance.
