The Honeywell Home ST9400C1000 is a programmable heating controller providing 7-day control of two heating zones: central heating and hot water. It allows separate heating and hot water programmes with up to three on/off periods per day, making it easy to schedule your heating around your routine.

The LCD display provides clear information and straightforward programming, while the holiday mode allows temporary changes to your heating schedule when you're away.
