   For a vertical mount, put screws on the top and bottom. For a horizontal mount, put screws on the left and the right.

Caution:
Electrical Hazard
Disconnect power before installing this product. Failure to do so can cause electric shock or equipment damage.

Mercury Notice
This product is mercury-free. However, if this product is replacing a control that contains mercury, it needs to be disposed of properly. Contact your local waste management authority for instructions regarding recycling and proper disposal of the control.

Mounting & Battery Installation

Mounting Thermostat

Align the 4 tabs on the faceplate with the corresponding slots on the back of the thermostat, then push gently until the thermostat snaps into place.

Wiring

Terminal Designations

This thermostat is shipped from the factory to operate a conventional heating and cooling system. This thermostat may also be configured for a heat pump system. See the “heat pump” configuration step on page 14 of this manual to configure the thermostat for heat pump applications.

Terminal	2 Heat 2 Cool Conventional System	2 Heat 1 Cool Heat Pump System	3 Heat 2 Cool Heat Pump System
RC	24 VAC power (Cooling)	24 VAC power (Cooling)	24 VAC power (Cooling)
RH	24 VAC power (Heating)	24 VAC power (Heating)	24 VAC power (Heating)
C	24 VAC common	24 VAC common	24 VAC common
B	Reversing valve / configurable terminal	Reversing valve / configurable terminal	Reversing valve / configurable terminal
O	Reversing valve / configurable terminal	Reversing valve / configurable terminal	Reversing valve / configurable terminal
G	Fan relay	Fan relay	Fan relay
W/E	First stage of heat	Emergency Heat	The first stage of auxiliary heat
Y	The first stage of cool	The first stage of heat & cool	The first stage of heat & cool
Y2	The second stage of cool	N/A	The second stage of heat & cool
W2	The second stage of heat	Auxiliary heat	The second stage of auxiliary heat

Wiring Notes
Common wire
The C (common wire) is optional when the thermostat is powered by batteries.
Wire Specifications
Use 18- to 22-gauge thermostat wire. Shielded wire is not required.
Notes:
In many heat pump systems without emergency heat relay, a jumper can be installed between E and W2 to the turn thermostat into a single-stage control for Emergency Heat Operation.
Installation Tip: Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the sub-base correctly or cause system operation issues. Max Torque = 6in/lbs.

1. Power supply
2. Factory-installed jumper. Remove only when installing on 2-transformer systems.
3. Use either O or B terminals for reversing valve.
4. Optional 24 VAC commom connection when thermostat is used in battery power mode.

Typical 2H/2C System: 1 Transformer

Note:
In many systems with no emergency heat relay a jumper can be installed between E and W2

Installer Setup Menu

1. Press MENU.
2. Press and hold TECHNICIAN SETUP for 3 seconds.
3. Configure the installer options as desired using the table below.
4. Use or change settings and NEW STEP or PREV STEP to move from one step to another.
   Note: Only press DONE when you want to exit the Installer Setup options.

Programming Notes

The second stage will turn ON at 2x the differential setting and OFF at 1x the differential setting. For example, if the differential setting is 0.5° for heating and the thermostat is set at 70°F, the first stage will turn on at 69.5°F. The second stage will turn on at 69°F and turn off at 69.5°F. If the third stage is used, the third stage will turn on at 68.5°F and turn off at 69°F.

Keypad Lockout
The installer can activate a keypad lockout after exiting Tech Setup.

Contractor Call Number
If the contractor call number is selected ON, the selected phone number will show in the display if there has been a continuous call for heating or cooling for 24 hours or if the FAN button is held down for 3 seconds. To remove the phone number from the display, hold the fan button down for 3 seconds.

This thermostat can be configured to have 7 Day or 5+1+1 programming. If 7 Day
is selected, all seven days will need to be programmed individually. If 5+1+1
programming is selected, Monday–Friday will be programmed together and
Saturday and Sunday will need to be programmed individually. There are four

6. The set-point temperature will be flashing. Use or to make your set-point selection for the WAKE time period for Monday–Friday (or Monday if in 7 Day mode).
7. Press NEXT STEP.
8. Repeat steps 4 through 7 for the LEAVE time period, for the RETURN time period, and for the SLEEP time period for Monday–Friday (or Monday if in 7 Day mode).
9. Repeat steps 4 through 8 for the Saturday WAKE, LEAVE, RETURN, and SLEEP time periods, and then again for the Sunday WAKE, LEAVE, RETURN, and SLEEP time periods for the 5+1+1 program schedule, and for each day for the 7-day program schedule.

	Leave	8 AM	62° F (17°C)	83°F(28° C)
	Return	6 PM	70°F (21°C)	75°F(24°C)
	Sleep	10 PM	62°F (17°C)	78°F(26°C)
Saturday	Wake	6 AM	70°F (21°C)	75°F(24°C)
	Leave	8 AM	62°F (17°C)	83°F(28°C)
	Return	6 PM	70°F (21°C)	75°F(24°C)
	Sleep	10 PM	62°F (17°C)	78°F(26°C)
Sunday	Wake	6 AM	70°F (21°C)	75°F(24°C)
	Leave	8 AM	62°F (17°C)	83°F(28°C)
	Return	6 PM	70°F (21°C)	75°F(24°C)
	Sleep	10 PM	62°F (17°C)	78°F(26°C)

Auto Changeover: In Auto mode, users can toggle between Auto Heat or Auto Cool by pressing System only when the current mode has reached its temperature set point. To switch out of Auto mode, hold down System. To return to Auto mode, toggle the System key to Auto.
Programmable Fan: The programmable fan feature will run the fan continuously during any time period it is programmed to be on. This is the best way to keep the air circulated and to eliminate hot and cold spots in your building.
Reminders: Once a Reminder has been turned on and set, the elapsed time can be checked by navigating the Tech Setup step. The time can be reset by pressing and holding the third button from the left for 3 seconds. Resetting an expired Reminder can be done by pressing and holding the 3rd button from the left for 3 seconds.
