ST9500C 2-Zone Programmer

INSTALLATION INSTRUCTIONS

Introduction

ST9500 is an Electronic Programmer which provides accurate time control for central heating systems with separate 7 day programmes for two independent heating zones.

ST9500 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.

Mounting

The Programmer should be mounted at a level where the display can be seen clearly, (1.2 to1.5m from the ﬂoor) and the ambient temperature is within the range of 0 to 40°C. The ST9500 is for use in normal domestic environments.

CAUTION

Isolate power supply and make safe before wiring the unit to prevent

electric shock and equipment damage. Installation should be carried

out by a qualiﬁed electrician or competent heating engineer.

surface wiring in mini trunking

Ensure the mounting surface is supporting and fully covers the wiring wall-plate.

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.
