Replacing Existing Thermostat cont.
4.
After labeling and removing all wires from terminals, unscrew the existing thermostat
sub-base from wall. Make sure to secure wires to prevent them from slipping back
into the hole in the wall.
NOTE: This thermostat is designed for use with a 24 Volt AC low voltage
multi-stage heat pump system. Do not use this thermostat on applications with
voltages above 30 Volts AC.
2.2
Installing Your New Thermostat
NOTE: If you are installing this thermostat in a new installation be sure to locate
the thermostat 4 to 5 feet above the floor in accordance with applicable building
codes. Make sure to install the thermostat in a location that provides good airflow
characteristics and avoid areas behind doors, near corners, air vents, direct sunlight
or near any heat generating device. Installation in any of these areas could impact
thermostat performance.
TESTING YOUR
NEW THERMOSTAT
3
NOTE: Test your thermostat prior to programming any user settings. Pressing the
RESET button will erase any user entries for time of day, day of week, option settings
and programming if previously programmed. This will erase all user settings and
return them to their default values.
WARNING!
Read BEFORE Testing
• Do not short (or jumper) across terminals on the heating or cooling system
control board to test the thermostat installation. This could damage the thermostat
and void the warranty.
• Do not select COOL mode of operation if the outside temperature is below
50˚ F (10˚ 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 heat pump system from short cycling. This thermostat
automatically provides a 5-minute delay after turning off the heating or cooling
heat pump output to protect the compressor.
