Figure 1. Thermostat Base

FAN (ELE/GAS) SWITCH

For Electric Heat, heat pump or any system that requires the thermostat to turn on the blower on a call for heat– place the FAN (Ele/Gas) switch (Fig. 1) in the ON position. For Auxiliary and Emergency Heat systems that have a fan control to turn on the blower (independent of the thermostat) place switch in the OFF position.

BATTERY LOCATION

ATTACH THERMOSTAT BASE TO WALL

1. Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit.

2. Place base over hole in wall and mark mounting hole locations on wall using base as a template (see Fig.1).

3. Move base out of the way. Drill mounting holes.

4. Push wires through opening in thermostat base.

5. Fasten base loosely to wall using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase.

6. Connect wires to terminals on base using appropriate wiring schematic (see ﬁgs. 2 through 4).

7. Push excess wire into wall and plug hole with a ﬁre-resistant material (such as ﬁberglass insulation) to prevent drafts from affecting thermostat operation.

O/B TERMINAL SWITCH SELECTION

The O/B switch on this thermostat is factory set to the “O” position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in HEAT, the O/B switch must be moved to the “B” position.

Two “AA” alkaline batteries are installed in your thermostat with a battery tag to prevent power drainage. Prior to use, open the battery door and remove the battery tag. To open, pull the battery door as shown by the arrow and lift open. The two “AA” batteries will operate all functions or maintain time and continuously display the temperature during a loss of AC power. Installed batteries will also allow programming prior to installation. To replace batteries, pull the battery door shown by the arrow and lift open. Using the polarity indicated inside the battery door, insert the batteries. To close the battery door, swing the door down while pulling in the direction of arrow. Once fully down, snap the door back into position.

Thermostat can be powered by system AC power or Battery. If

is displayed, the thermostat is battery powered. If is not displayed, thermostat is system powered with optional battery back-up. When battery power remaining is approximately half, the

will be displayed. When “Change ” is displayed,

install fresh “AA” alkaline batteries immediately. For best results, use new premium brand alkaline batteries such as Duracell® or Energizer®. We recommend replacing batteries every 2 years. If the home is going to be unoccupied for an extended period (over 3 months) and

is displayed, the 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

or . Another offset will occur within two days if batteries are not replaced. To replace the batteries, set system to OFF.

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 switch to OFF. Press and hold the and buttons simultaneously for approximately 5 seconds. The display will change to show the ﬁrst item in the conﬁguration menu. Press the or button to change the setting. Press the and buttons simultaneously again to change to the next menu item. Continue through all steps to accept your new settings. To exit the menu set the system switch to COOL, HEAT or EMER. If no keys are pressed within ﬁfteen minutes, the thermostat will revert to normal operation.

1) Select CS (Cool Savings™) - With Cool Savings™

enabled, the thermostat will make small adjustments to the Setpoint temperature during periods of high demand to reduce cooling system running time and save energy. When the cooling system has been running for more than 20 minutes, humidity in the home will be lower and a higher setpoint temperature will feel comfortable. After 20 minutes of run time, the thermostat will start increasing the setpoint temperature in steps of less than one degree as the system continues to run. These adjustments will eventually cause the system to satisfy the thermostat and turn the system off to reduce the energy consumption. When the Cool Savings feature is active and making adjustments, the display will show “Save”. The amount of the adjustments to the setpoint temperature is dependent on the Cool Savings value that

is set, 1 being the least adjustment and 6 being the most adjustment. With this feature set to OFF, no change will occur when the cooling system is continuously running during the periods of high demand. Periods of high demand will normally occur during the late afternoon and early evening on the hottest days of the summer.

2 & 3) Select Cycle Rate Selection - The factory default

setting is (FA, CR) for all modes (Heat Pump, Heat Pump Aux, Heat and Cool). To change to slow cycling (SL, CR), press the or keys to toggle between FA & SL.

The cycle rate differentials for different settings are:

MODE Fast Slow

FA SL

Heat Pump 1.2°F 1.7°F HP Aux 0.8°F 1.2°F

4) Select Compressor Lockout CL OFF or ON - Selecting

CL On will cause the thermostat to wait 5 minutes between cooling cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the lockout feature is already present in their system. When the thermostat compressor time delay occurs, it will ﬂash the setpoint for up to ﬁve minutes.
