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.

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.

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.

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.
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...

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.

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.

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.
Installer Settings There are a number of 'Installer Settings' that should be set on installation. These can be found under the 'SET UP MENU' on page 13 of the user instructions. Clock Format AM/PM or 24 Hour clock display - Default setting AM/PM Daylight saving On or Off - Default setting ON...

Note 1: Unless otherwise stated all command classes are version 1 Note 2: “The Delta T” is the change between temperature readings required for the SCS311 or SCS317 to send temperature reports to the Gateway node in Association Group 1. Setting this to its lowest value, 0.1˚C, will provide more frequent updates but at higher cost to the...
