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.
To remove the unit from the wall-plate, slacken the two securing screws at
the bottom of the ST9500 and hinge the unit up to separate the two halves.
Wiring
