PRECAUTIONS
WARNING
!
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
Thermostat installation and all components of the
system shall conform to Class II (current limited)
circuits per the NEC code. Failure to do so could cause
a fire hazard.

Page 2: Remove Old Thermostat
INSTALLATION REMOVE OLD THERMOSTAT 1. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. 2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. -

INSTALLATION batteries should be replaced before leaving. When less than two months of battery life remain, the setpoint temperature will offset by 10 degrees (10 degrees cooler in Heat mode / 10 degrees warmer in Cool mode). If offset occurs, the normal setpoint can be manually reset with will occur within two days if batteries are not replaced. -

THERMOSTAT QUICK REFERENCE Before you begin programming your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons and switches (see fig. 3). Your thermostat consists of two parts: the thermostat cover and the base. -
Page 5: Installer Configuration Menu
INSTALLER/CONFIGURATION MENU The configuration menu allows you to set certain thermostat operating characteristics to your system or personal requirements. To enter the menu: Set your thermostat to OFF and press the first item in the configuration menu.

PROGRAMMING Enter Heating Program 1. Move the SYSTEM switch to HEAT. 2. Press PRGM once. “Mo Tu We Th Fr” (indicating weekday program) will appear in the display. Also displayed are the currently programmed start time for the 1st heating period and the currently programmed temperature (flashing). -
Page 9: Troubleshooting
TROUBLESHOOTING Reset Operation If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, reset the thermostat by pressing the and PRGM buttons simultaneously. If Symptom Possible Cause No Heat/No Cool/No Fan 1. Blown fuse or tripped circuit breaker. (common problems) 2. - Page 10 TROUBLESHOOTING STAGING Second Stage - Auxiliary Heat Most heat pump systems have an Auxiliary or Second Stage electric heater or gas furnace. Heat produced by a heat pump is economical but may not always have the capacity to maintain a comfortable room temperature setting. Auxiliary/Second Stage heat is usually less economical but the added heat capacity assures the system can provide enough heat to satisfy the thermostat setting.
