Introduction

ST9100 is an Electronic Timer which provides accurate time control for central heating systems and other applications. ST9100A is a 1-day version and ST9100C is a 7-day version. ST9100 is suitable for replacing a wide range of Timers on the market, and is a direct replacement for Honeywell ST6100 Timers without the need for re-wiring. ST9100 Timers 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.

Wiring

ALL WIRING MUST BE IN ACCORDANCE WITH I.E.E. REGULATIONS. THIS UNIT IS FOR FIXED WIRING ONLY.
A switch, having contact separation of at least 3mm in all poles (formerly Class ‘A’), must be incorporated in the fixed wiring as a means of disconnecting the supply. The unit is a Class II (double insulated) device. A parking terminal is provided for external earth continuity. The system must be appropriately fused. A fuse rated at no more than 3 Amps should be installed. The unit has 4 knockouts for surface wiring, care must be taken to ensure that the cable or mini-trunking completely fills the knockout hole without leaving any gaps

Final Assembly

• Clip the unit onto the hinges on the top of the wallplate and hinge down into position. Tighten the two securing screws using a screwdriver.
• Switch on the power – the unit will now be operating according to the built-in programme. Note : the ST9100 is supplied with a factory set clock for faster installation .
• Refer to ST9100 User Guides for programming details
