SMART RECOVERY
Smart recovery is a feature of your thermostat designed to save energy by
gradually adjusting temperatures. When it’s time for a programmed
temperature change, smart recovery begins working in advance, turning the
system on and off as needed to slowly adjust the indoor temperature.
During these transition periods, you may notice that the actual temperature
and your temperature setting don’t match. That’s smart recovery in action,
adjusting temperatures in small increments for greater energy efficiency.
This is more energy efficient than simply allowing the system to operate at
full capacity until the desired temperature has been met. Smart Recovery
helps avoid excessive use of auxiliary heat when recovering from night
setback in the heating mode.
EVENTS PER DAY
This is where you can set the number of events per
day. (An event is a period of time scheduled with a
certain heating and cooling set point.) For instance if
you are away from your home from 8am to 5pm,
make this period of time an event and set the
thermostat at an energy saving setting. You have the
option of setting the events per day to 4-
RESIDENTIAL (4 events), 2-RESIDENTIAL (2 events) or 2-BUSINESS
(2 events).
4-RESIDENTIAL 2-RESIDENTIAL 2-BUSINESS
(Default)
SMART HEAT STAGING (
HEAT PUMP ONLY)
This will delay the thermostat from engaging in 3
rd
stage heating if needed.
Options are ON or OFF. Default is OFF. Range for this are 0-120 minutes
in 5 minute increments, if set to ON. 30 minutes is the default time. This
is the time before the electric heat or furnace is engaged if a 3
rd
stage of
heat is required. This option does not work in dual fuel operation.
COOLING LOCKOUT
(HEAT PUMP ONLY)
When an outdoor temperature sensor is installed, you can set it up so
cooling option doesn’t energize if the outdoor temperature is below a
certain temperature. Ranges for this are NONE (default), 45
˚
F, 50
˚
F, or
55
˚
F.
ELECTRIC HEAT LOCKOUT
(HEAT PUMP + ELECTRIC HEAT ONLY)
/
FURNACE LOCKOUT (anytime Electric Heat is not selected)
When an outdoor temperature sensor is installed, you can set it up so the
electric heat option doesn’t energize if the outdoor temperature is above a
certain temperature. Ranges for this are NONE (default), 5
˚
F to 60
˚
F in 5
˚
increments.
BALANCE POINT
(HEAT PUMP ONLY)
When an outdoor temperature sensor is installed, you can set it up so the
heat pump doesn’t energize in heat if the outdoor temperature is below a
certain temperature. Ranges for this are NONE (default),
5
˚
F to 55
˚
F in 5
˚
increments. Below this setting in dual fuel mode the Furnace only will run.
INTERMITTENT FAN
Temperature conditions can vary widely between the thermostat location
and extremities of the space the thermostat serves. This air stratification
problem can be especially pronounced during mild outdoor conditions
when long periods elapse between space conditioning demands from the
thermostat. This intermittent fan operation can also improve the
performance of air cleaning or special filtration systems that locate the
cleaning or filtration media at the return air side of the fan.

If the FAN hasn’t been on for an hour, the fan
will start cycling based on these times. Default is
OFF. The first screen is the amount of time you
want the fan to be energized. Ranges are OFF, or 5-20 minutes in 5
minute increments.

After entering this time and pressing the center button
■
, the next screen
is the amount of time the fan is OFF. Ranges are
0 minutes, or 5-40 minutes in 5 minute
increments.

Fan ON and OFF cycles will continue until the
fan has been energized by a call for heating or cooling.
DUAL FUEL OPERATION
When the Thermostat is configured for a heat pump with dual fuel heating
operation, the heating call will start with a Y1 output to run the heat pump
compressor (above Balance Point). If the heat pump is a 2 stage system,
the Y2 output can come on if there is enough demand for second stage
heating (above Balance Point). If there is a demand for heat and the
outdoor ambient temperature is below the Balance Point the stat will
lockout the compressor and energize the Furnace only.
If the heat pump goes into a defrost cycle, the furnace will turn on and the
heat pump Y1 and/or Y2 will stay on for the duration of the defrost cycle.
The Furnace will continue to run after the completion of the defrost cycle
while locking out the compressor, if the demand for heat is still present,
until the demand for heat has been satisfied. Upon next call for heat the
stat will energize the appropriate stage of heat based on the Balance Point.
If the defrost cycle last longer than 15 minutes a fault has occurred and the
thermostat will set the output to complete the heat call with the furnace and
turn off the heat pump. The screen will show DEFROST ERROR on the
top line. While this error exists, the heat pump will not run. To reset the
fault, highlight the RESET FAULT location at the bottom of the main
screen and press the center button
■
. This will reset the fault and allow the
system to try to run normally. If the error persists, service is needed.
OUTDOOR SENSOR
If the system is equipped with an outdoor temperature sensor (REQUIRED
FOR DUAL FUEL OPERATION) it is possible to allow the thermostat to
operate the heat pump system in the most efficient manner possible. By
setting the ELECTERIC HEAT LOCKOUT, and the HEAT PUMP
LOCKOUT you can avoid running the heat pump when the outdoor
temperature is too low to operate efficiently. You can also avoid running
the electric heat when the outdoor temperature is high enough to allow the
heat pump to maintain a comfortable temperature.
The OUTDOOR sensor is connected to the OD and GND terminals on the
thermostat.
