Honeywell ST9400S User manual

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.

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.

ADDITIONAL PRODUCT FEATURES
Boiler Service Reminder / Shut-down Feature
The ST9400S Service Interval Programmer has been developed to assist
Social Housing Landlords to comply with the requirements of Regulation
36 of the Gas Safety (Installation & Use) Regulations 1998. It is intended
as an aid to compliance but should not be used to replace the Landlord’s
existing Servicing procedures.
The ST9400S performs like a standard programmer. In addition it can
automatically provide a Service Reminder and can be set to Shut-down
the heating / hot water system once the gas Boiler Service becomes
overdue. This helps to eliminate the potential for an incident to occur
after the Landlord’s Safety Certificate has expired.
The operation of the Service Feature is flexible. The landlord or installer
can set the following:
• The service interval, in days
• An advance reminder for the tenant, by counting down days until
service is due
• A telephone number to call to arrange the service – displayed on the
LCD screen
• How the timer will operate when the service interval has expired.
The options include:
1. Continued normal operation with a Reminder message
2. Total shutdown of heating and hot water
3. “Prompt” mode – shutdown that will allow repetitive
manual over-ride for one hour at a time.
The Service feature is configured from a special Installer Mode called
‘SET SERVICE’. Entry into this mode is only possible by entering a
unique 4 digit PIN code.
Note: The ST9400S is supplied from the factory with the Service features
DISABLED. They need to be enabled from the Installer Modes. See
following section ‘Installer Modes’ for details.
Replacement Wiring
If using the ST9400S to replace other Honeywell Programmers, the equivalent wiring terminations are shown in the tables below. Installer Setup
Installer Setup parameters are listed in the table below, along with a description of the options that are possible.
Installer Modes
ST9400S has 3 Installer Modes that enable the product to be customized
for the application and for the needs of the User. Each adjustable feature
is called a Parameter, and is represented by a number or letter ID and a
value. The Modes are:-
• Installer Setup
This is the same as the Installer Setup for standard ST9000 time controls.
It allows features to be adjusted to suit user lifestyles or preferences, for
example; backlight operation, automatic time-change, and selection of
the default time programme. It is entered by a combination of button
presses.
• Set Service
This is where the ST9400S Boiler Service Reminder and Shut-down
Features can be set. This mode can only be entered by using a 4
digit PIN code. The factory supplied default PIN code is 0000
• Change PIN
This mode allows the 4-digit PIN code to be adjusted. It is itself
protected by the PIN code. When the code is changed this new code
is used to enter both SET SERVICE and CHANGE PIN modes.
To Enter & Navigate Around the Installer Modes:
a. Ensure the slider is in the RUN position, then press and hold
and buttons together for 8 seconds. Ignore the ‘NOT VALID’
that is displayed for a few seconds. The message ‘SET UP MENU’
will show briefly, to indicate you have entered the Setup menu. The
LoT™ Display will continue to show messages indicating which
Installer Mode is possible to select, for example ‘SET INSTALLER
OK ?’
b. Use the or buttons to navigate to the correct Installer
Mode.
c. Use the button to confirm you wish to enter that particular mode.
To Exit Installer Modes:
You can exit the Installer Modes at any time by moving the slider to the
next position and then back again to RUN. Any changes that have been
confirmed will be saved and used.
Note: The Installer Modes and the Setup Menu will exit automatically
after 10 minutes if the slider is not moved and no adjustments have been
made in this time.
