Installer Options Menu
The SMT-131 has an impressive list of options that can be installer selected. These options tune
the thermostat’s performance as well as set energy conservation settings. This menu is
deliberately hidden and difficult to enter to discourage unauthorised tampering.
The information card provided in the SMT-131 box provides details on how to enter the SMT-131
menu. If this is lost, please contact Smart Temp or an authorised distributor for support.
Navigating Through the Installer Mode Settings
The bottom right button steps forward through the menu options, the bottom left button steps
you backwards.
Adjust your options with the up/down buttons.
Exit the menu saving changes by pressing and holding the
bottom right or wait 3 minutes and the SMT-131 will
automatically exit the installer menu.
The current menu option is shown between the left and right buttons. The example to the right
shows option 3, select deg C (option 0) or F display (option 1).
Note. Option 3 in the installer menu described below sets the SMT-131 native temperature
display format as deg C or Deg F modes. Temperature options in the installer options use the
native temperature format.
