ST9400S is an Electronic Programmer which provides accurate time control for central heating systems with separate programmes for heating and hot water. It has an in-built Boiler Service Reminder / Shut-down Feature developed to assist Social Housing Landlords to comply with the requirements of Regulation 36 of the Gas Safety (Installation & Use) Regulations 1998. This is intended as an aid to compliance but should not be used to replace the Landlords existing Servicing procedures.
ST9400S is suitable for replacing a wide range of Programmers on the market, and is a direct replacement for Honeywell ST6400 Programmers without the need for re-wiring.
ST9400S Programmers can be combined with other Honeywell controls such as Room Thermostats, Cylinder Thermostats, Wiring Centres and Zone or Diverting Valves to form a fully automatic central heating control system
