7 Day Wireless Programmable Room
Thermostat and SR303 Receiver
Programmable room thermostats are widely recognised as one
of the best ways in which to control central heating. The CS317
programmable room thermostat has a large display and intuitive
user interface, making it easy to set up and use. CS317 uses a
sophisticated time proportional integral (TPI) algorithm for
accurate temperature control and energy efficiency.

What is a programmable room thermostat?
...an explanation for householders.
A programmable room thermostat is both a programmer and a
room thermostat. A programmer allows you to set 'ON and OFF'
time periods to suit your own lifestyle. A room thermostat works
by sensing the air temperature, switching on the heating when
the air temperature falls below the thermostat setting and
switching it off once the set temperature has been reached.
So, a programmable room thermostat lets you choose what
times you want the heating to be on, and what temperature it
should reach while it is on. It will allow you to select different
temperatures in your home at different times of the day (and
days of the week) to meet your particular needs.
Turning a programmable 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 the boiler and radiators. Neither does the
setting affect how quickly the room cools down. Turning a
programmable room thermostat to a lower setting will result in
the room being controlled at a lower temperature, and saves
energy.
The way to set and use your programmable room thermostat is
to find the lowest temperature settings that you are comfortable
with at the different times you have chosen, and then leave it
alone to do its job. The best way to do this is to set low
temperatures first, say 18ºC and then turn them up by one
degree each day until you are comfortable with the
temperatures. You won't have to adjust the thermostat further.
Any adjustments above these settings will waste energy and
cost you more money.

If your heating system is a boiler with radiators, there will usually
be only one programmable 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 chose 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.
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.
Programmable 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.

TEMPORARY OVERRIDE
A temporary temperature change can be made at any time. It is
also possible to extend how long this temperature override is in
operation.
The temperature will revert to its normal programmed setting at
the next timed temperature change
TEMPORARY OVERRIDE WITH TIME EXTENSION
(Maximum of 4 hours)
The temperature will revert to its normal programmed setting
at the next timed temperature change.

MAIN MENU
To access the MAIN MENU take the following steps:
MENU OPTIONS
Press ENTER twice Press '-' or '+' to
toggle between the
menu options
Programme This allows the user to adjust the different
time and temperature settings from the
factory default settings shown in the table on
page 8.
Up to six different temperature levels can be
set in any 24 hour period
Standby This puts the CS317 into Frost protection or
Standby condition and allows the heating to
be permanently switched off but will activate
and switch the heating on if the temperature
in the house falls below the standby
temperature set.
All programme settings are overridden and
the unit will not return to normal operation
until the standby period has ended by
pressing the ENTER button.
Holiday This puts the CS317 into a temporary
standby mode with a start and end date
which can be set to coincide with a holiday
period. At the end of the set period the
CS317 will resume normal operation
Time / Date The CS317 has a built in clock and calendar.
This will require setting on initial installation. If
this has not been set on installation please go
to Setting the TIME and DATE section on
page 14 before continuing
Set Up Enables the programming of various options
outlined in the SET UP MENU on page 15 of
these instructions – These should be set on
installation.

Setting the PROGRAMME
Six time and temperature settings are available in each 24 hour period.
Pressing BACK at any time in this process will return you to normal
operating mode.
If only two different temperature settings are required in 24 hours then set
the first time and temperature using programme one (P1) and the second
time and temperature setting using programme setting two (P2). The
remaining programmes (P3 to P6) should all be set to the same time and
temperature as P2.
This same method can be used if three, four or five temperature levels are
required, always using the first settings to provide the temperature change
commands with the remaining settings that are not required set to the same
time and temperature as the last required setting.
