  • Honeywell ST9400A 24 Hour 2 Channel Programmer

    The Honeywell ST9400A 24 Hour 2 Channel Programmer designed to allow the user to control both the central heating and stored hot water independently. By controlling the central heating and hot water separately the system runs more efficiently helping users to reduce their energy bills and carbon footprint. The ST9400A has three on/off switching times per day allowing the user to set the heating and hot water to come on at three different times per day at the same times every day of the week. The ST9400A can be used for combi boilers, heating zones or any application where small electric loads need switching. It can also be set as a mini programmer for older gravity feed hot water systems where there is no interlocking control valve. 

    The Honeywell ST9400A 24 Hour 2 Channel Programmer has a clear Line of Text display that provides plain English instruction whenever a slider or button is used making this a highly user friendly programmer. Also the ST9400A 24 Hour 2 Channel Programmer has superseded the ST6400A which is no longer available.  

    Key Features:

    • Clear Line of Text display, providing text feedback that gives help and programming hints
    • Factory set time and date
    • Automatic Summer/Winter 1 hour time change
    • Temporary or permanent override facilities
