Honeywell Home ST9400A Programmer 24Hr 2 Channel. This programmer is part of the Honeywell Home range and is a timer which allows you to control two systems, your central heating and your hot water, all from one control. On/Off periods can be set to match your lifestyle, leading to less energy wastage and lower energy bills.

As a timer, it does not directly control the temperature alone, but working together with thermostats allows both the hot water and the central heating temperatures to be controlled.

Despite being an uncomplicated product, the ST9400A is capable of setting the hot water and central heating to turn on and off separately at different times from one another.
