SYSTEM START--UP AND CHECKOUT
The Thermidistat Control is designed with a built--in installer test capability. It
allows easy operation of equipment without delays or setpoint adjustments to force
heating or cooling. To enable installer test mode, press and hold the fan button for
15 seconds. After 10 seconds, the Thermidistat Control will enter Configuration
Mode. Continuing to hold the Fan button through 15 seconds will cause the
Thermidistat Control to enter Installer Test Mode. Pressing the Mode button will
change the system operating mode to test the heating and cooling equipment. Auto
Mode is not available during Installer Test Mode. If no buttons are pressed for 15
minutes, the installer test mode will be terminated. Pressing DONE at any time will
exit installer test mode.
Heat -- The first stage of heating will be energized for three minutes, then the first
and second stages (if a second stage exists) will turn on for an additional three
minutes. During the first stage of heating, the HEAT ON icons will be displayed.
During the second stage of heating (if one exists), the “2” next to the “On” will be
displayed if the system has a two--stage compressor (A2, h2, or H2 unit types). The
“auxiliary heat on” icon will be displayed if the second stage is electric heat (HP
unit type). While the heating test is active, the humidify output can be toggled. On
the programmable models, pressing the button below the humidify icon shall toggle
the state of the humidify output. On the non--programmable models, pressing the
features button shall toggle the state of the humidify output.
Installer test for cooling is the same as described for heating above. COOL ON will
be displayed during cooling in Installer Test Mode. While the cooling test is active,
the dehumidify icon shall be displayed if the dry contact has been configured as a
DH output. On the programmable models, pressing the button below the
dehumidify icon shall toggle the state of the dry contact output. On the
non--programmable models, pressing the features button shall toggle the state of the
dry contact.
