Parameter Name/Description
REMOTE SENSOR — Determines whether the remote sensor hardware input is:
• NONE — Not used
• NONE or SPACE — The outdoor temperature is acquired by Wi-Fi through the server,
based on the location of the mobile device used to connect the thermostat to a
router, or based on the ISP location, if a computer connects the thermostat to a
router.
• OUTDOOR — Senses the outdoor temperature
NOTE The outdoor temperature is not available if the thermostat is not connected to
Wi-Fi or if you do not select OUTDOOR.
• AVERAGE — Space temperature results from averaging the internal the external
sensor
• OCCUPANCY — An external source is accessed to determine if the setpoints are
Occupied or Unoccupied. When Normally Open contacts close, the Occupied
setpoints are used.
NOTE When selected, the NON-PROG setting is automatically set and is not
displayed in the Installer Settings until this parameter is changed.
• FAULT INPUT— An external source is used to detect a fault, as determined by the
attached Economizer.

COOL LOCKOUT — Delays the cooling equipment demands if the outdoor air temperature
is below the selected value. There is a SYSTEM EVENT warning if the mode and space
temperature dictate that there should be a cooling demand and the outdoor temperature
is preventing this demand.
55°F
OFF
0°F to 80°F in 5°F
increments
LOW COOL LOCKOUT — (Heat pump operation only) Enables the thermostat to start all
cooling stages on a demand for cooling based on the configured value. Normal cooling
always starts with first stage compressor (Y1) and stages up to the second (Y2), when
the demand is sufficient and staging and cycle timer constraints are satisfied.
If the outdoor temperature is equal to or greater than the configured value of 80°F to
110°F, all stages of cooling are energized. If set to ON, all stages are energized on a call
for cooling. The outdoor temperature must also be greater than the
COOL LOCKOUT
value. When a cooling cycle starts under a high cool latch, it finishes the cooling cycle on
HIGH STAGE. If the cooling equipment is energized to satisfy a dehumidify demand only
(no cooling demand), the latch is not applied.

LOW HEAT LOCKOUT — (Heat Pump operation only) Enables the thermostat to start all
compressor heating stages on a demand for heating, based the configured value. When
the COMPRESSOR TYPE is set to HP and compressor heat is requested, it always starts
with the first compressor stage (Y1) and stages up to second stage (Y1 and Y2) when the
demand is sufficient and staging and cycle timer constraints have been satisfied.
If the outdoor temperature is equal to or less than the configured value of 20°F to 50°F,
both the first and second stages of the compressor are energized to satisfy all heat
pump heating demands. If set to ON, both compressors are energized on a call for
heating. The outdoor temperature must also be greater than the HP LOCKOUT value.
When a cycle starts under a high heat latch, it finishes the heating cycle on HIGH STAGE.
OFF
20°F to 50°F in 5°F

TIME BETWEEN FUEL TYPES
— The minimum time limit between switching from one fuel
type to another (other staging rules may also be in effect). It is only used if the
COMPRESSOR TYPE is set for HP.
15 minutes
10, 15, 20, 25 minutes.
