heating and two stages of cooling.

READ ALL INSTRUCTIONS BEFORE PROCEEDING

WARNING!

Important Safety Information

• Always turn off power to the air conditioning or heating system prior to

installing, removing, cleaning or servicing thermostat.

• Read manual thoroughly prior to installing, programming or operating thermostat.

• This thermostat is designed for use with a 24 Volt-AC low voltage multi-stage

heat / cool system.

• Do not use this thermostat on systems with voltages higher than 30 Volt-AC.

• This thermostat requires 24 Volt AC power for normal operation and control of

the heating or cooling system.

• Wiring must conform to all building codes and ordinances as required by local

and national code authorities having jurisdiction.

• 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 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 should only be used as described in this manual. Any other use

is not recommended and will void the warranty.

INSTALLATION

2.1

Replacing Existing Thermostat

Always turn off power to the air conditioning or heating system prior to removing

existing thermostat.

Remove the cover of your old thermostat and locate the wire terminals. Do not

remove wires from terminals yet.

Using small pieces of masking tape label wires prior to removal from terminals. Use

the chart below to determine the new terminal designations for your new thermostat.

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.

INSTALLATION 2.1 Replacing Existing Thermostat cont. cont. NOTE: This thermostat is for use on low voltage 24 Volt AC multi-stage heat / cool systems with up to two stages of heating and two stages of cooling and requires a transformer common wire for proper installation. This thermostat is not for use on single stage heating or cooling systems. 2.

TROUBLESHOOTING cont. 6 TROUBLESHOOTING cont. SYMPTOM POTENTIAL SOLUTION SYMPTOM POTENTIAL SOLUTION Thermostat display is blank. It is possible that AC power is not present at the thermostat. Check fuse, circuit breaker and thermostat wiring as appropriate to verify AC power is available. Fan continues to run in cooling mode when the system has turned off. The Residual Cooling Fan Control Feature can allow up to a 90 second fan delay after cooling system shutdown for energy efficiency gains.
