tion. It can be configured for Heat Pump or two stage

al system, your options are:

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
selection. If less cycles are desired, choose the Econ-
omy selection.
2. Advanced Setup — Compressor Lockout
This menu item controls the compressor lockout
feature. This feature is intended to help protect the
compressor from short cycling. Some newer com-
pressors 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,
A/C return < 5 min
will be displayed
on the messaging area of the thermostat.
Options for this menu item include:
•
OFF
– (Default) No compressor wait time. Assumes
lockout feature is already present.
•
ON
– Waits 5 minutes before turning on the com-
pressor 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 thermo-
stat will turn off the air condition/heat pump compres-
sor if a condition exists that may potentially damage
the system.
4. Advanced Setup — Frost Protection
Frost protection when enabled ON provides pro-
tection 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.
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

on all available stages whenever the setpoint it manu-
ally changed 3 degrees or more from the current room
temperature.
7. Advanced Setup — Dual Fuel (Available When
NOTE: It is important to select the proper set-
ting for this option, even if you skip the rest of
the Configuration menu.
