Testing the Thermostat
WARNING!
• Do not short (or jumper) across terminals on the gas valve or at the heating or
cooling system control board to test the thermostat installation. This could
damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below
50º F (10º C). This could possibly damage the controlled cooling system and
may cause personal injury.
• This thermostat includes an automatic compressor protection feature to
avoid potential damage to the cooling system from short cycling. The default
is to provide a 5-minute delay after turning off the cooling or heating output to
protect the compressor. This default can be changed in Section 4, Option 12,
Programming Installer Options.
NOTE: Test your thermostat prior to programming any user settings. Pressing the
Installer CLEAR button will reset the thermostat to all factory default settings. See
Page 4 and 5 for a complete listing. See Page 5 for a list of all functions that will
return to their default settings after the RESET button is pressed.
1. Using the system button, scroll through settings on the left side of the display
to HEAT.
2. Press the button on the keypad until the set point temperature setting is
a minimum of 3 degrees higher than the current room temperature. The
heating system should start within several seconds. The fan may not turn
on immediately due to the heating system built-in fan delay.
3. Scroll through system settings to OFF. The heating system should stop within
several seconds.
4. Scroll through system settings to COOL.
5. If the compressor has previously been running, then you must wait 5 minutes,
or until the installer programmed delay set in Section 4, Option 12, for the
automatic compressor short cycle protection period to expire. You can also
press the RESET button to bypass this feature for initial testing purposes.
See Section 4, Page 5 for a list of all functions that will return to their factory
default settings after the RESET button is pressed.
6. Press the button on the keypad until the set point temperature is a minimum
of 3 degrees lower than the current room temperature.
7. The cooling system should start within several seconds. Scroll through system
settings to OFF. The cooling system should stop within 90 seconds (dependent
on the setting of the Residual Cooling Fan Feature).
8. Scroll the fan settings to ON, the system blower should start.
9. Scroll the fan settings to AUTO, the system blower should stop.
10. If thermostat is controlling auxiliary equipment, adjust thermostat setting to test
humidifier, economizer, etc. if applicable.
