22 Auto Changeover Dead Band [note 10] – When auto changeover mode is enabled in option 5 and
selected, the system automatically switches between heating and cooling when the room temperature
meets the normal criteria for either a heating or cooling call. There is a forced separation (dead band)
between the heating and cooling set points so that the systems do not work against each other. This
option selects the amount of this dead band in degrees with the default being 3° F.
23 Compressor Balance Point [notes 4, 11] – Locks out the use of the compressor heat stage when the
outside air temperature is less than the selected setting of 15° F to 50° F (-9° C to 10° C)
24 Auxiliary Heat Balance Point [notes 4, 11] – Locks out the use of the auxiliary heat stage when the
outside air temperature exceeds the selected setting of 70° F to 40° F (21° C to 4° C). NOTE: This
balance point overrides the fossil fuel compressor lockout in option 13. If this option is set to gas and
the outdoor temperature is over the auxiliary balance point, the compressor will remain on during a call
for auxiliary heat.
25 Heat Set Point Upper Limit – Selects the heating set point upper adjustment limit.
26 Cool Set Point Lower Limit [note 7] – Selects the cooling set point lower adjustment limit.
5 System Testing
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
compressor from short cycling. When testing the system, make sure to take this delay into account.
NOTE: The compressor delay can be bypassed by pressing the reset button on the front of the thermostat.
All user settings will be returned to factory default, however all Installer settings will remain as originally
programmed in section 4.
1
Press the SYSTEM button until the thermostat is in HEAT mode.
2
Using the
button, raise the set temperature a minimum of 3 degrees above the current room
temperature. The system should start within a few seconds. With a gas heating system, the fan may
not start right away.
3
Press SYSTEM until the thermostat is in the OFF mode. Allow the heating system to fully shut down.
4
Press SYSTEM until the thermostat is in the COOL mode.
5
Using the
button, lower the set temperature a minimum of 3 degrees below the current room
temperature. The system should start within a few seconds (unless compressor short cycle protection
is active – See note above).
6
Press SYSTEM until the thermostat is in the OFF mode. Allow the cooling system to fully shut down.
7
Press FAN until the thermostat is in FAN ON mode. The system fan should start within a few seconds.
8
Press FAN until the thermostat is in FAN AUTO mode. Allow the system fan to turn off.
