This Honeywell Home ST9400C Programmer offers timing control for central heating and hot water systems. Providing both 7 or 5/2 day schedules, with a maximum of 3 on/off heating cycles per day, this timer allows residents to align hot water and central heating systems with their daily requirements.

Please note that this hot water and central heating programmer does not directly control temperature, and should therefore be installed alongside a Honeywell thermostat.
