SCS311 / SCS317
Installation Instructions
SCS311 or SCS317 Wireless Programmable
Room Thermostat
1
Programmable room thermostats are widely recognised as one
of the best ways in which to control central heating. The SCS311
& SCS317 programmable room thermostats have a large
display and intuitive user interface, making them easy to set up
and use. The SCS311 & SCS317 use a sophisticated time
proportional integral (TPI) algorithm for accurate temperature
control and energy efficiency. The SCS311 & SCS317 operate
within a wider Z-Wave RF network, as a secondary or inclusion
controller under any 3rd party gateway or other primary
controller. When operating in a network that includes a gateway,
it offers full access to the heating program whilst still maintaining
control of the devices within its heating sub system. The SCS311
& SCS317 use the Wake Up Command Class to synchronise
and exchange data with any 3rd party Gateway or Controller.
Installation and connection should only be carried out by a
suitable qualified person and in accordance with the relevant
wiring regulations.
Warning: Isolate mains supply before commencing installation.
TPI Temperature control software
Thermostats using TPI (Time Proportional Integral) control
algorithms will reduce the temperature swing that normally
occurs when using traditional bellows or thermally operated
thermostats. As a consequence, a TPI regulating thermostat will
maintain the comfort level far more efficiently than any
traditional thermostat.
When used with a condensing boiler, the TPI thermostat will help
to save energy as the control algorithm allows the boiler to
operate in condensing mode more consistently compared to
older types of thermostat.
ŸFor Gas boilers set the TPI setting to 6 cycles per hour (default
setting)
ŸFor Oil boilers set the TPI setting to 3 cycles per hour
ŸFor Electric heating set the TPI setting to 12 cycles per hour
To adjust this setting go to the SET UP MENU and select TPI

Fitting the SCS311 / SCS317 Programmable Room
Thermostat
First install the 2 x AA batteries provided making sure that they
are fitted correctly as indicated by the markings in the battery
compartment on the front of the SCS311 and SCS317.
Once the SCS311 or SCS317 is successfully included / paired
the SCS311 or SCS317 can be installed in its correct location.
Avoid installing the SCS311 / SCS317 against or behind any
large metal surfaces which could interfere with the radio signals.
The SCS311 / SCS317 should be mounted on an internal wall
approximately 1.5 metres from floor level using the wall plate
provided and should be in a position away from draughts, direct
heat and sunlight. Ensure that there will be enough space to
allow easy access to the two retaining screws located at the
base of the wall plate.

Before fixing the wall plate in position check to see that the
thermostat is still able to communicate satisfactorily with the
controller by turning the thermostat temperature up the
controller should provide the appropriate response.
Offer the plate to the wall in the position where the SCS311 /
SCS317 is to be mounted and mark the fixing positions through
the slots in the wall plate. Drill and plug the wall, then secure the
plate into position. The slots in the wall plate will compensate for
any misalignment of the fixings.
Complete installation by swinging the SCS311 / SCS317 into
position by engaging with the lugs at the top of the wall plate
before pushing it carefully home into its plug-in terminal block.
Tighten the 2 captive screws on the underside of the unit.

Select clock format This allows the display to show the time in
24 hour or AM/PM format
Daylight saving This is the adjustment made in the UK when
the clocks go back or forward in the Autumn
and Spring
Default setting ON
Standby temperature This is the temperature setting used when in
Standby or Holiday mode (Min 5˚C / Max
30˚C)
In cold weather the heating will activate if
the temperature being measured falls below
this temperature setting
Lower temperature limit This sets the lowest temperature setting the
SCS311 or SCS317 will allow to be
programmed
Default setting 5˚C
Menu Options
6
Upper temperature limit This sets the highest temperature setting the
SCS311 or SCS317 will allow to be
programmed
Default setting is 30˚C
TPI cycles per hour This setting helps the TPI energy saving
software to operate correctly depending on
the type of heating system you have
Optimum start This calculates the amount of time the
SCS311 or SCS317 may need to switch on
in advance of the next target temperature
setting in order to meet the requirement
Tamper setting This setting allows a 4 digit release code to
be set up to stop unauthorised adjustments
being made in multi occupancy buildings
Set up Z-Wave Sub Menu Description
Include node / receiver Include other devices
onto the network.
Exclude node / receiver Remove devices from
a network.
Send NIF Sends a Node
Information Frame
(NIF) as a broadcast
message.
Learn Used for inclusion or
exclusion by another
controller. This mode
can be used for the
reception of the
primary controller role
following a controller
shift initiated by the
current primary
controller.
7
Listen Puts the SCS311 or
SCS317 into listen
mode, for up to 60
seconds.
Associate node Used to manually
associate devices to
control.
Disassociate node Used to manually
disassociate all
associated
switches.
Controller shift Used to offer the
Primary Controller role
to another controller.
Protocol reset Used to reset the Z-
Wave network.
Include / Exclude
When the Include/Exclude function has been selected it will wait
for a request to join the network from another node.
If the installer does not start the Inclusion/Exclusion process of
the other node within 60s, or the SCS311 or SCS317 does not
receive a response within 3 minutes from another node, then a
failed outcome will be indicated.
Note 1: When including a device that supports Thermostat Mode HEAT, the
SCS311 or SCS317 will automatically associate it to Group 2 (switch
association group).
Note 2: If an associated node to SCS311 or SCS317 is excluded from the
network, it will be removed from the Association Group it is stored in.
Learn
When the Learn function has been selected the SCS 311 or
SCS317 will wait to be included to or excluded from another
controller.
If the installer does not start the inclusion/exclusion process of
the other node within 60s, or the SCS311 or SCS317 does not
receive a response within 3 minutes of beginning exclusion with
another node, then a failed outcome will be indicated.
Note 1: any associations will be cleared if the SCS 311 /317 have engaged
in Learn mode with another controller regardless or a successful or failed
outcome.
Note 2: the SCS 311 /317 does not support control group replication.
Listen
Puts the SCS311 or SCS317 into a listening state enabling it to
receive messages outside of the Wake Up Notification Period.
This state lasts for at least 60 seconds or until the user cancels it
by pressing BACK.
Associate/Disassociate
This function allows the installer to manually associate
/disassociate devices to Association Group 2. When associated
the node will be under direct control of the SCS311 or SCS317
heating algorithms. On selecting associate, the installer has 60s
to initiate a NIF from desired node. In the event of the 60s period
elapsing a failed message will be shown on the display.
8
Controller Shift
This allows the installer to manually relinquish the primary
controller role of the SCS311 or SCS317. When selecting
Controller Shift the installer have 60s to initiate Learn Mode on
the other controller for the controller shift to take place. (The
SCS311 and SCS317 will timer out after 3min if a acceptable
response is not received)
If the operation is successful the SCS311 or SCS317 will
become a secondary or inclusion controller depending on the
new primary controller's capabilities.
Protocol Reset
Provides a full protocol reset and a restoration of all network
parameters to their defaults, and generates a new random home
ID to operate on. A network reset does not change the heating
schedules stored on the device.
A success or failure message will be shown on the display within
5 seconds.
Network Update Scheme
When the SCS311 or SCS317 is a secondary or inclusion
controller with a SUC or SIS present in the system, it will request
network updates every four hours, to ensure that it has an up to
date version of the network table
