Completion
All wiring must be in accordance with IEE Regulations. This thermostat is for xed wiring only.
A switch, having contact separation of at least 3mm in all poles, must be
incorporated in the fixed wiring as a means of disconnecting the supply.
The thermostat is a Class II (double insulated) device. A parking
terminal is provided for external earth wiring continuity.
The heating system must be appropriately fused. Most typical wet
heating systems should be fused at 3 Amps. Warm air and electrical
systems may have a higher load. Maximum fuse ratings are 10 Amps
for T6360B and T4360E, or 16 Amps for T4360B.
The thermostat has 4 knockouts on the cover for surface wiring
installations. Care must be taken to use the knockouts so that the cable
completely fills the knockout hole without leaving any gaps. Where
used, mini-trunking must be fitted firmly against the thermostat cover
For T6360B and T4360E a neutral connection must be made to
terminal 2 when the heating load is less than 6 Amps.
Replacement
For Central Heating applications up to 6 Amps, use T6360B.
For application between 6 Amps and 10 Amps, again use a T6360B,
but without the neutral connection (see above note regarding neutral
connection).
Use T4360B in high current applications up to 16 Amps.
EMC compliance considerations
Keep AC mains supply/load cables separate from signal wiring.
Refer to Code of Practice EN61000-5-1 and -2 for guidance.
in such a way as to leave no gap.

What is a room thermostat? …an explanation for householders
A room thermostat simply switches the heating system on and off as
necessary. It works by sensing the air temperature, switching on the
heating when the air temperature falls below the thermostat setting,
and switching it off once this set temperature has been reached.
Turning a room thermostat to a higher setting will not make the room heat
up any faster. How quickly the room heats up depends on the design of
the heating system, for example, the size of boiler and radiators.
Neither does the setting affect how quickly the room cools down.
Turning a room thermostat to a lower setting will result in the room
being controlled at a lower temperature, and saves energy.
The heating system will not work if a time switch or programmer has
switched it off.
The way to set and use your room thermostat is to find the lowest
temperature setting that you are comfortable with, and then leave it
alone to do its job. The best way to do this is to set the room thermostat
to a low temperature – say 18ºC – and then turn it up by one degree
each day until you are comfortable with the
temperature. You won’t have to adjust the
thermostat further. Any adjustment above
this setting will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will usually
be only one room thermostat to control the whole house. But you
can have different temperatures in individual rooms by installing
thermostatic radiator valves (TRVs) on individual radiators. If
you don’t have TRVs, you should choose a temperature that is
reasonable for the whole house. If you do have TRVs, you can
choose a slightly higher setting to make sure that even the coldest
room is comfortable, then prevent any overheating in other rooms
by adjusting the TRVs.
Room thermostats need a free flow of air to sense the temperature,
so they must not be covered by curtains or blocked by furniture.
Nearby electric fires, televisions, wall or table lamps may prevent
the thermostat from working properly.
