Mounting
If the ST9400S is replacing an existing ST6400 then the existing wall-plate
and wiring may be used, subject to any required electrical checks.
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 ST9400S 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 ST9400S and hinge the unit up to separate the two
halves.

ST9400S Programmer
With Boiler Service Reminder / Shut-down Feature
INSTALLATION INSTRUCTIONS
50022736-006 A
Introduction
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 Landlord’s 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.
