SCS311 or SCS317 Wireless Programmable
Room Thermostat
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.

Room Thermostat 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. - Page 2 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.
- Page 3 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.
- Page 4 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.

- Page 7 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.
- Page 8 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.
- Page 9 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.
