£71.50 (£59.58 ex. VAT)

The Honeywell ST9400C Seven Day 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 ST9400C Two Channel unit gives great flexibility offering up to three on/off switchings per day, additionally each day can be programmed differently, which is ideal for when the user has different heating needs from day to day. It can be set to 5/2 day or 1 day programme during installation.

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
