CP318
USER OPERATING INSTRUCTIONS
The CP318 combined wireless room stat and time control allows
a combi boiler system to have a room thermostat added without
the need for any additional wiring.
Replacing the existing time controller with the CP318 will allow the
room thermostat to be connected wirelessly producing immediate
energy savings in houses where no previous room thermostat
has been fitted.
The device is intended to upgrade existing combi boiler systems
that do not have an existing room thermostat. It is not intended for
new installations where it will be necessary to install two heating
zones in order to comply with current Building Regulations.
Combined Timeswitch and Room Thermostat
1
The CP318 is a timeswitch which is connected to its own room
thermostat - using the latest Z-wave wireless technology.
Where it has been used to replace your existing time control it is
likely that there was no room thermostat fitted previously.
The addition of this room thermostat will make considerable
energy savings which independent tests have shown could be as
much as 10% off your energy bills.
The thermostat uses the latest micro-processor controlled energy
saving software – known as TPI - which is a very accurate
temperature control method compared to older style mechanical
room thermostats. It runs on two AAA batteries which should last
more than 2 years and a battery low indicator will appear in the
display of the thermostat when they need changing.
The timeswitch is mains powered with a reserve battery to retain
its memory during power cuts. It will allow up to 3 On/Off settings
per day for each day of the week and has a 1 hour boost button
and an On/Off advance button.
There is also a programme override allowing the permanent
selection of OFF/ON/AUTO/ALL DAY.
General system - explanation for householder
2
The room thermostat will only operate during
‘On’ periods set by the time control which is
always indicated by the red neon indicator light
on the front. If there is no light then the heating
is ‘Off’ and the room thermostat is inoperative.
When the timeswitch is ‘On’ (shown by the red
indicator light) the thermostat will be
operational and will provide very accurate
control of the room temperature.
When the thermostat is ‘calling’ for heat the flame
symbol will appear in the thermostat display and if the
timeswitch is ‘On’ the heating will be operative and will
run under the control of the timeswitch and the
temperature set on the room thermostat.
The thermostat is silent in operation – it does not ‘click’ on and off
like older style thermostats. The contacts on the timeswitch will
do the actual switching rather than the thermostat which is linked
to it by Z wave wireless signals.
The indicator against the radio mast
symbol on the CP318 shows that the
radio link is established.
A flashing indicator means that the
wireless connection has been
temporarily lost. This is usually restored
by going to the thermostat and turning
the dial up and down.
If no indicator is present next to the radio mast symbol then this
would suggest that the timeswitch and the thermostat have not
been paired correctly on installation. (See pairing instructions in
the Installation Guide).

What is a programmer?
... an explantion for householders.
Programmers allow you to set ‘On’ and ‘Off’ time periods. Some
models switch the central heating and domestic hot water on and
off at the same time; while others allow the domestic hot
waterand heating to come on and go off at different times. Set the
‘On’ and ‘Off’ time periods to suit your own lifestyle. On some
programmers you must also set whether you want the heating
and hot water to run continuously, run under the chosen ‘On’ and
‘Off’ heating periods, or be permanently off.
The time on the programmer must be correct. Some types have
to be adjusted in Spring and Autumn at the changes between
Greenwich Mean Time and British Summer Time. You may be
able to temporarily adjust the heating programme, for example,
‘Override’, ‘Advance’ or ‘Boost’. These are explained in the
manufacturer’s instructions.
The heating will not work if the room thermostat has switched the
heating off. And, if you have a hot-water cylinder, the water
heating will not work if the cylinder thermostat detects that the hot
water has reached the correct temperature.
The above explanation also applies to your timeswitch,
which operates as a single circuit programmer.

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 18¡C – 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.
5
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.

Programme Override Facilities
With the CP318 timeswitch operating in the normal running mode
it is possible to alter the functionality of the programme by means
of the SELECT button.
The options include;
Auto - Timeswitch follows all programmed ‘ON’ and ‘OFF’ times.
All day - Timeswitch operates from 1st ‘ON’ time until 3rd ’OFF’,
ignoring all switching times in between.
24hrs - Timeswitch will be constantly ‘ON’.
Off - Timeswitch will be constantly ‘OFF’, there is the ability to
turn off the heating during the summer without altering the
programme times. Boost is still available.
All of the settings above will be permanent, i.e. unaffected by
programme times, until alteration by the user.
The diagram below illustrates how to alter the setting, it assumes
that the programme is in the AUTO mode to begin with.

Electronic equipment can in some circumstances be affected by
electrical interference. If the programmer’s display becomes
frozen or scrambled; or if you wish to revert back to the default
time settings please reset by pressing the SET and SELECT
buttons together as shown below.
After initial installation it is advisable, before programming the
CP318 for the first time, to reset the unit. Resetting can only be
achieved with the power ‘ON’ by pressing the SET and SELECT
buttons together. This will return the programmer to the factory
set default times.
Resetting the timeswitch
Press the SET and SELECT buttons
together then release the buttons
and the programmer will return to
preset factory settings SET
