PRODUCT SPECIFICATION SHEET
The T4360/T6360 range of thermostats
are designed to provide automatic
ON/OFF control for gas valves,
circulation pumps, relays and zone
valves in all heating, cooling, or
heating/cooling installations where
single or changeover switching up to
10 A (resistive load) or 3 A (inductive
load) is required.
In addition a 16 A (resistive load)
variant is available for direct switching
of high current carrying loads.
Nine models of the thermostat are
available, in a wide range of feature
combinations.
FEATURES
• Dual diaphragm sensing element ensures close
temperature control for all loads and applications
• Attractive modern styling makes this thermostat ideal
for locating in the living space
• Available with or without heat anticipation to suit the
application
• The T6360 has changeover contacts for use in
cooling or heating/cooling applications
• Versions with switches for positive-off selection, or
summer/ winter (heat/cool) changeover operation
• Mounts directly onto wall or conduit box
• Improved eas
conductor clamps to ensure wiring is retained
securely
-to-wire terminals with built-in
• Double insulated. No earth wire required for
operation. Earth "parking" terminal available on
selected models
• Optional extras available are:
– range stops F42006646-001
– tamperproof cover F42007110-001 (opaque) or
F42007110-002 (transparent)
– additional wallplate for special mounting
requirements F42007789-001

INSTALLATION
IMPORTAN
1. The installer must be a trained service engineer
2. Disconnect the power supply before beginning
installation
Location
A T4360/T6360 room thermostat is the temperature control
element in your heating system and must be located in a
position with good air circulation at average temperature - on
an inside wall about 1.5 m above the floor.
Do not position the thermostat in draughts, near hot or cold
air from water pipes or radiant heat from the sun or
appliances.

Mounting the thermostat
The T4360/T6360 can be mounted directly on the wall or on a
conduit box (see Fig. 2). Mounting screws are provided for
both alternatives.
An additional wall-plate is available for special mounting
requirements.
Wiring the thermostat
The standard wiring access is via a hole in the base of the
thermostat, near the top edge. There are also 4 breakouts
on the cover (2 on top and 2 on the sides) for surface wiring
requirements.
Wall box mounting
Fixing holes spaced to
suit BS4662
screws supplied

OPERATION
Sensing Element
The thermostat sensing element comprises two circular,
flexible metal plates welded together at the rims
encapsulating a small quantity of gas (0.125g) in liquid form,
whose pressure changes greatly in response to small
variations in temperature. In effect, this dual diaphragm
forms a 'bellows' which expands/contracts in sympathy with
the ambient temperature changes - this movement serving to
operate a snap acting switch rated to control the heating or
cooling circuit.
Heat Anticipator
It is recommended that a thermostat with heat anticipator is
used for systems with a high heating ramp rate. This will
overcome the overshoot and undershoot problems often
found in this type of installation.
Indicator Lamp
A 'potential-free' indicator lamp is available on some models.
This can be wired as required to indicate when power has
been switched to the (heating or cooling) load (see Wiring).
To wire the lamp as 'boiler lockout' indicator, follow boiler
manufacturers wiring instructions.
Surface mounting
Use wall box fixing holes
or alternatives shown
screws supplied
Auxiliary Switches
The on/off switch provides a means of manually isolating the
mains input to the thermostat, to provide a positive off
feature.
The summer/winter switch provides the user with a means of
manually switching between a heating output (activated on
temperature fall) to a cooling output (activated on
temperature rise).
Frost Protect Thermostat
The frost protect thermostat prevents water pipes from
freezing in exposed locations. It should be positioned close
to where the pipework is most exposed to external chilling
and connected to override all existing time and temperature
controls. The frost protect thermostat is provided with an
indicator mark at the 5
tamperproof cover.
o
C point, and is supplied with a
Disposal of Thermostat
The thermostat contains no user serviceable parts. Please
ensure product disposal is in a safe and environmentally
friendly manner, in compliance with local regulations. Do not
dispose of in a fire.
