Notes: (1) A permanent mains supply must be provided for the ST9400 Programmer.
(2) ST9400 must be confi gured as a Mini-Programmer
Replacing Other Manufacturers' Time Controls
ST9400 Programmers will mount directly onto many existing manufacturers' back-plates, without the need for re-wiring. However, they are also
supplied complete with a wiring back-plate, should this not be the case.
Refer to Honeywell for wiring conversion diagrams. (see Wiring Guide document EN3H2393 Issue 12)

ST9400A & ST9400C Programmer
INSTALLATION INSTRUCTIONS

Introduction
ST9400 is an Electronic Programmer which provides accurate time
8
control for central heating systems with separate programmes for
heating and hot water. ST9400A is a 1-day version and ST9400C is a
3
7-day version.
ST9400 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.
ST9400 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
If the ST9400 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 fl oor) and the ambient temperature is
within the range of 0 to 40°C. The ST9400 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 qualifi ed electrician or competent heating engineer.
To remove the unit from the wall-plate, slacken the two securing screws at
the bottom of the ST9400 and hinge the unit up to separate the two halves.
Wiring
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 ST9400 is supplied with a factory set
clock for faster installation .
Refer to ST9400 User Guides for programming details.
