For battery power, insert the 2 supplied “AA” type alka-
line batteries into the battery compartment located in the
rear housing of the thermostat. Make sure to position the
Positive (+) and Negative (-) sides of the batteries cor-
rectly with the +/- symbols in the battery compartment.
For 24 Volt AC power, you must connect the common
side of the transformer to the C terminal on the thermostat
sub-base. In dual transformer installations, the tranformer
common must come from the cooling transformer.

weekend) programming or non-programmable.
3Clock Type – Selects either a 12 hour or 24 hour clock.
4Temperature Scale – Selects a temperature scale of either °F or °C.

selected, the system automatically switches between heating and cooling modes. There is a 5 minute
delay when switching from heating to cooling or cooling to heating in auto changeover mode.

11 Installer Manual
82nd Stage Differential [note 2] – Selects a 2nd stage temperature differential.
93rd Stage Differential [note 2] – Selects a 3rd stage temperature differential.
10 1st Stage Fan Control [note 3] – Selects a 1st stage fan control of either gas or electric heat.
11 Emergency Heat Fan Control [note 4] – Selects emergency heat fan control of either gas or electric heat.
12 Reversing Valve [note 5] – Selects the output state of the O/B terminal. Select O for this terminal to
be active in the cool mode or select B for this terminal to be active in the heat mode.
13 Auxiliary Fossil Fuel Heat Pump Control [note 4] – When set to electric (AE AUX), both the compressor
(1st stage) and auxiliary stage(s) will run when a call for auxiliary heat is made. When set to gas (AG AUX),
the compressor stage(s) will be locked out one minute after a call for auxiliary heat. NOTE: This option can
be overridden if setting an auxiliary heat balance point in Option 24.
14 Compressor Power Outage Protection [notes 4, 6] – Selects power outage protection on or off. When
enabled, this thermostat will provide cold weather compressor protection by locking out the compressor
stage(s) of heating for a period of time after a power outage greater than 60 minutes.
15 AC Power Interrupt Warning [note 6] – When enabled, the thermostat will display an outage warning
when AC power to the thermostat is lost.
16 Short Cycle Protection [note 7] – Selects the number of minutes the cooling compressor will be
locked out after turning off. This short cycle protection is also active in the heat mode if a heat pump
system was selected in Option 6.
17 Residual Cooling Fan Delay [note 7] – Selects a delay for the system fan after the cooling compressor
has turned off. This delay will help remove the remaining cool air out of the ductwork providing
additional efficiency.
18 Circulating Fan Lock – When enabled, the only user fan options available are ON and CIRC (Circulation).
The AUTO option is not available with this option enabled.
19 Adaptive Recovery Mode (early recovery) [note 8] – Enables or disables the ARMTM (adaptive recovery
mode) feature. During ARM, room temperature is recovered by turning on the heating or cooling before the
end of the set back period. The set point temperature is changed to that of the upcoming program temperature.
20 Indoor Remote Sensor Control [note 9] – If an indoor remote sensor is connected during installation,
the thermostat will automatically detect the sensor. When an indoor sensor is detected, you may select
between thermostat only (I SENS), remote sensor only (E SENS) or combining the thermostat and the
remote sensor (A SENS). NOTE: This option does not apply to an outdoor sensor. When an outdoor sensor
is connected the thermostat automatically recognizes it and no further configuration is necessary.
21 Lockout Security Level – Selects the level of keypad lockout when the thermostat is locked. Level
2 locks the entire thermostat (including the front reset button). Level 1 locks everything except the
/ buttons, allowing for up and down temperature adjustment. NOTE: The lock code is set in the
User Settings mode (see User Manual).

22 Auto Changeover Dead Band [note 10] – When auto changeover mode is enabled in option 5 and
selected, the system automatically switches between heating and cooling when the room temperature
meets the normal criteria for either a heating or cooling call. There is a forced separation (dead band)
between the heating and cooling set points so that the systems do not work against each other. This
option selects the amount of this dead band in degrees with the default being 3° F.
23 Compressor Balance Point [notes 4, 11] – Locks out the use of the compressor heat stage when the
outside air temperature is less than the selected setting of 15° F to 50° F (-9° C to 10° C)
24 Auxiliary Heat Balance Point [notes 4, 11] – Locks out the use of the auxiliary heat stage when the
outside air temperature exceeds the selected setting of 70° F to 40° F (21° C to 4° C). NOTE: This
balance point overrides the fossil fuel compressor lockout in option 13. If this option is set to gas and
the outdoor temperature is over the auxiliary balance point, the compressor will remain on during a call
for auxiliary heat.
25 Heat Set Point Upper Limit – Selects the heating set point upper adjustment limit.
26 Cool Set Point Lower Limit [note 7] – Selects the cooling set point lower adjustment limit.
Installer Manual 12
Warning
Read Before Testing
• 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 the COOL mode of operation if the outside temperature is below 50º F (10º 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
compressor from short cycling. When testing the system, make sure to take this delay into account.
NOTE: The compressor delay can be bypassed by pressing the reset button on the front of the thermostat.
All user settings will be returned to factory default, however all Installer settings will remain as originally
programmed in section 4.
1Press the SYSTEM button until the thermostat is in HEAT mode.
2Using the button, raise the set temperature a minimum of 3 degrees above the current room
temperature. The system should start within a few seconds. With a gas heating system, the fan may
not start right away.
3Press SYSTEM until the thermostat is in the OFF mode. Allow the heating system to fully shut down.
4Press SYSTEM until the thermostat is in the COOL mode.
5Using the button, lower the set temperature a minimum of 3 degrees below the current room
temperature. The system should start within a few seconds (unless compressor short cycle protection
is active – See note above).
6Press SYSTEM until the thermostat is in the OFF mode. Allow the cooling system to fully shut down.
7Press FAN until the thermostat is in FAN ON mode. The system fan should start within a few seconds.
8Press FAN until the thermostat is in FAN AUTO mode. Allow the system fan to turn off.

Este termostato requiere energía de 24 V de CA o 2 baterías alcalinas tipo “AA” instaladas cor-
rectamente para su adecuado funcionamiento. Al conectar la energía a 24 V de CA, las baterías
se pueden instalar como respaldo. La instalación del termostato y todos los componentes del
sistema deberán conformarse a los Circuitos de clase II del código NEC
.
Solamente se debe usar como se describe en este manual. Cualquier otro uso anulará la garantía.

Manual del instalación 2
Para energizar mediante baterías, introduzca las
2 baterías alcalinas tipo “AA” suministradas en el
compartimiento ubicado en la parte posterior de la caja
del termostato. Asegúrese de colocar correctamente los
lados positivo (+) y negativo (-) con los signos +/- del
compartimiento de baterías.
Para energía a 24 voltios de CA, debe conectar el lado
común del transformador a la terminal C de la sub-base
del termostato. En instalaciones de doble transformador,
la línea común del transformador debe venir del transfor-
mador de aire acondicionado.
