3.3. STEP 2: Mounting the
New Thermostat
WARNING! Take care when securing and
routing wires so they do not short to adjacent
terminals or rear of thermostat. Personal injury and/or property damage may occur.
To prevent personal injury and/or property damage,
contact Customer Service at your utility company
before attempting any step in the installation process
that you are unsure about how to perform.
3.3.1. Mount the New Thermostat

ing material from the thermostat. Gently pull the
thermostat straight off of the base: hold the thermostat from the back by the lower corners with one
hand, and pull the Mounting Plate off with the other
hand.
wires are fed through. Each terminal is labeled with
a letter or a letter with a number (O, B, R, etc.).
Connect the wires as follows:
• Strip insulation about 3/8 inch from end of wire.
• Feed the thermostat wires through the rectangular
hole in the thermostat Mounting Plate.
• Locate the terminal that the wire needs to connect to
(refer to Section 5, Wiring Chart).
• Bend the wire slightly, insert the wire under the contact plate, and tighten the screw down onto the wire.
For full details on where to connect each wire, see
Section 5, Wiring Chart.

• ON – Waits 5 minutes before turning on the compressor after a power loss or during cooling/heating
cycles. Protects the compressor from short cycling.
3. Advanced Setup — Comfort Alert Active
Protection
The Commercial Communicating Programmable
Thermostat is competitive with the Copeland Comfort
alert protocol. When connected to the comfort alert
module and active protection is selected, the thermostat will turn off the air condition/heat pump compressor if a condition exists that may potentially damage
the system.
4. Advanced Setup — Frost Protection
Frost protection when enabled ON provides protection by activating heat even if system switch is
OFF when the Room Temperature falls to 42° F. Heat
will stay on until room temperature rises above 42° F.
If Thermostat is Heat Pump configured thermostat
will use Auxiliary heat in Frost Protection mode.
9.2. Advanced Setup
1. Advanced Setup — Cycle Rate
This menu item controls and provides choices of
Comfort, Standard (default), and Economy cycle rates
for Heating, Cooling and Back-up Heat (on heat
pump configuration). Normal setting is standard if
more frequent cycles are desired choose the Comfort

HVAC Equipment Setup Description of Installation Menu Options • 25
5. Advanced Setup — O/B Configuration
This configures whether the O/B terminal for the
heat pump reversing valve will be energized during
cool (O) or heat (B) mode.
6. Advanced Setup — Fast Second Stage
(Multistage Systems)
A selection of on will enable the thermostat to turn
on all available stages whenever the setpoint it manually changed 3 degrees or more from the current room
temperature.
7. Advanced Setup — Dual Fuel (Available When
Page 33
Configured for Heat Pump with Gas Furnace)
The thermostat has the capability to control dual
fuel systems without an outdoor sensor or Smart Fuel
logic.
8. Advanced Setup — Dual Fuel by Smart Fuel
Operation
In the Smart fuel logic configuration, the Commercial Communicating Programmable Thermostat
can determine when the heat pump is no longer efficient and optimize system changeover to the fossil
fuel back-up. In the Smart Fuel Logic menu, you have
a choice of 1-9 settings. Default setting is 5 and can be
adjusted up to 9 to bring on fossil fuel sooner at higher
outdoor temperature or down to 1 to keep the heat
pump on at a lower outdoor temperature.
9. Advanced Setup — Dual Fuel by Sensor
Operation (Available When Outdoor Sensor is
Connected and Enabled)
In sensor configuration the Commercial Communicating Programmable Thermostat you can select the
outdoor ambient temperature (HP Lockout) the system will switch from heat pump to fossil fuel
(-20 to 30° F range). You can also select an outdoor
ambient at which temperature and above the Auxiliary heat is disabled (Aux Lockout selection range 34 to
90° F).
10. Advanced Setup — Heat Pump Comfort /
Economy Operation in Heat mode (Available
when configured for Heat Pump)
Comfort mode: In Heating mode. If the heat pump
is not able to satisfy the heating setpoint, the auxiliary
heat will be energized to satisfy the same heating set
point.
Economy mode: In Heating mode. If the heat pump
is not able to satisfy the heating setpoint, the auxiliary
heat will be energized to satisfy only when the temperature has dropped 2.0° F (1.1° C) below the heating setpoint. Selecting economy mode will add a
deadband between the heat pump & auxiliary heat in
heating mode. The actual temperature maintained will
be lower than the true heating setpoint to maximize
the heat pump efficiency.
11. Advanced Setup — Heat Lockout Outdoor
(Available When Outdoor Air Sensor is Enabled)
Disables heating operation based on outdoor air
temperature. When the outdoor air temperature is
above this value, all heating is disabled. (Setting
range is from -15 to 120° F.)
12. Advanced Setup — Cool Lockout Outdoor
(Available When Outdoor Air sensor is Enabled)
Disables cooling operation based on outdoor air
temperature. When the outdoor air temperature is below this value, all heating is disabled. (Setting range
is from -20 to 95° F.)
13. Advanced Setup — Compressor
Optimization
Allows for a more comfortable and efficient operation of heating and cooling. When the Compressor
Optimization is enabled “on” the circulator blower
(fan) will energize five seconds after the compressor
energizes when cooling (and heating for heat pump
applications). In cooling to extract additional cooling
form the system the circulator blower (fan) will remain energized for twenty seconds after the compressor de-energizes when cooling.
14. Advanced Setup — Dehumidification
This feature functions in the cooling mode and allows for dehumidification by enabling cooling operation to reduce humidity. You have two
dehumidification mode choices: Optimum Comfort
(OC) and Optimum Dehumidify (OD).
• Optimum Comfort (OC): Operates by alerting the
room temperature to a “feels like” temperature when
the indoor humidity level is above the user setting.
The altered temperature allows for longer cooling
cycles to lower the indoor humidity.
• Optimum Dehumidification: Operates by initiating a
cooling cycle when humidity level is above the user
setting and the room temperature is not less than
three degrees below the setpoint. Cooling will remain on until the humidity level drops to within 2%
of the setting, or the room temperature falls to 3 degrees below the setpoint.
15. Advanced Setup — Deadband
Deadband is a user selectable temperature range
the thermostat will maintain between the heating and
cooling setpoints while operating in auto-changeover
mode. In auto-changeover the cooling setpoint must
be higher than the heating setpoint to avoid a conflict.
The user can program the heat and cooling setpoints
at the same setting and the deadband will resolve setpoint conflicts. Default setting is 2 with a range of 2
to 4° F.
16. Advanced Setup — Power-up Delay
The feature will momentarily delay system startup after a power outage (each time 24VAC power
supply to thermostat is interrupted and reapplied) the
user can select a delay of operation of the system (fan,
cooling or heating). This feature can be used to se-

Furnace (Air Conditioner) Cycles Too Fast or Too Slow (Narrow or Wide Temperature Swing)
Possible Cause Corrective Action
Digital thermostats normally provide precise temperature control
The location of the thermostat and/or the size of
the heating system may be influencing the cycle
rate.
Table 10-7 - Furnace (Air Conditioner) Cycles Too Fast or Too Slow (Narrow or Wide Temperature Swing)
and may cycle faster than some older mechanical models. A faster
cycle rate means the unit turns on and off more frequently, but runs
for a shorter time so there is no increase in energy use. If you would
like to increase the cycle time, choose Economy for slow cycle in
the menu.
Second and Third Stage Won’t Come On
Possible Cause Corrective Action
Your thermostat is designed to determine the
optimum time to activate the second stage.
Simply raising the temperature in heating or
lowering it in cooling will not always force the
thermostat to bring the second stage on quickly.
There is a time delay from 0-30 minutes
depending on the performance of the fir st sta ge of
the system.
Table 10-8 - Second and Third Stage Won’t Come On
Wait for the second or third stage to come on.
10.1.Reset Operation
If a voltage spike or static discharge blanks out the
display or causes erratic thermostat operation, you
can cycle the thermostat power by unplugging the
thermostat from the baseplate for a few seconds then
plugging the thermostat back onto the mounting plate.
