Tranquility® Digital Quick Start Guide
Rev.: January 25, 2016
ClimateMaster Digital units are shipped from the factory
with default values for key parameters such as air fl ow and
water fl ow settings. The unit will operate with these default
settings, however, the installer may wish to customize these
settings to better match installation conditions. This guide
will walk the installer through those settings. More detail is
available in the unit IOM.
The fi rst step is to enter the Installer Menu. The fi rst time the
unit is powered up the ATC series thermostat display will take
you to the Installer’s Menu. Or you can enter the Installer’s
Menu anytime by placing the thermostat/system in the “OFF”
mode, then holding the “UP” and “DOWN” arrow keys simultaneously for 5 seconds. Once in the Installer’s Menu the
following menus will appear.
Step 1 Thermostat Confi guration
Upon initial power up, the communicating thermostat will
prompt the installer for the thermostat confi guration settings.
The software version of the thermostat and DXM2 board it
is connected to, are displayed on the thermostat Installer
Screen. If the DXM2 version is not displayed, the ATC thermostat is of an earlier version.
