Secure SCP318 Operation instructions

SCP318
USER OPERATING INSTRUCTIONS
The Secure SCP318 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 SCP318 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.
Single channel Z-Wave 7 day time control and
RF room thermostat

The SCP318 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 SCP318 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

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 timeswitch shows that the
radio link is established.
A flashing indicator means that the
wi r e l e s s c o nne c t i o n h a s be e n
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).

Programme Override Facilities
With the SCP318 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
timeswitch 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

The SCP318 timeswitch has a built in clock and calendar. This
will mean that you will need to enter the date as well as the time
on initial set up or if the factory re-set has been used.
Having done this, the clock will automatically adjust for BST/GMT
time changes throughout the year.

The Secure SCP318 thermostat
u s e s t h e l a te s t c o n t r o l
technology to provide extremely
accurate temperature control
which will help to keep your
energy usage as low as possible
without affecting your comfort
levels. In fact comfort levels may
well be improved as the control
accuracy should ensure that the
room does not ‘overheat’ before
switching off.
The display will show the required temperature setting and can
be adjusted in increments of 1°C. To adjust the required
temperature setting turn the dial anti clockwise to decrease it and
clockwise to increase it.
When the thermostat is in the ‘call for heat’
condition a flame symbol will appear in the display.
Pressing the temperature setting dial will allow the
user to check the current actual measured room
temperature which will be displayed for approx 7
seconds before returning to the set temperature.

Battery should
be changed
immediately
Low battery symbol
appears first when
the batteries are
nearing the end of
their life.
11
The aerial symbol complete with radio wave symbols
in the display of the thermostat indicates that it is
communicating satisfactorily with the timeswitch.
A flashing radio wave indicates a loss of
communication. This may be temporary and can
often be restored by turning the thermostat dial and increasing or
decreasing the temperature to make the thermostat switch. If this
has no effect please see Z-Wave pairing instructions.
A radio mast symbol with no radio waves indicates
that the thermostat has not been signed on to enable
it to communicate with the timeswitch. In this case
you may wish to contact the Installer as the
indication is that the product has not been
commissioned when the installation took place.
Alternatively see the Z-Wave pairing details contained in the
Installation Instructions. Further information on how the
thermostat operates is contained in the ‘Explanation for
householders’ that precedes this section.
Battery Replacement
The SCP318 thermostat runs on
2 x type AAA (Alkaline) non
rechargeable batteries and is
designed to give a battery life of
approximately two years.
When the batteries are nearing the end of their life a low battery
symbol will appear in the display and the batteries should be
changed within a few days. If the batteries are not changed at this
point eventually a ‘LO’ battery message flashes intermittently in
the display and if this happens the batteries should be changed
immediately.

To change the batteries it is necessary to remove the
thermostat from the wall. To do this first undo the two captive
screws at the base of the thermostat and swing the thermostat
up and away from the wall plate.
Remove the old batteries and replace them
with two new AAA size alkaline batteries
ensuring that they are fitted correctly as
indicated by the terminal markings in the
battery compartments.
Once the batteries are fitted, re-fit the
thermostat to the wall plate by engaging with
the lugs at the top of the wall plate and push the thermostat into
position. Locate it over the captive screws at the base of the wall
plate and tighten so that the thermostat is locked into position.
Check the temperature setting is correct and adjust if
necessary.

Please dispose of old batteries responsibly
