Installation Guide
Special functions
Fan Sequence Operations (Setup Function 0347, 0348, 0349): The thermostat comes factory default
with the fan ramping algorithm enabled (ISU 347). This gives the user the ability to select Auto-LoMed-Hi option in ISU 348 or Auto only option in ISU 348. Auto sets the thermostat into the fan ramping
algorithm mode and automatically sets the sufficient speed for PI control. Auto also automatically
shuts the fan off when there is not a call for heating or cooling. If the user decides to disable ISU 347,
then the fan will only have Lo-Med-Hi option available.
If ISU 347 is not enabled, then ISU 348 does not appear as a user selection choice.
If ISU 347 is enabled, then ISU 349 is available as a selection choice. The user can select either a 2
hour or 4 hour timer fan reset function. The fan will reset from a constant speed to auto mode after
the time period expires. If ISU 347 is not enabled, then ISU 349 does not appear as a user selection
choice.
Auto Changeover (Setup Function 0300): When set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature.
Compressor Protection (Setup Function 0580): Forces the compressor to wait a few minutes before
restarting, to prevent damage. During this time, the message “Wait” flashes on the display.
Special Programmable Mode Functions
Installer Setup 0160 allows the thermostat to be configured for either a mode with a programmable 7
day schedule or as a non-programmable thermostat.
Preoccupancy purge (ISU 0185): This feature is available only when the thermostat is configured as
a programmable schedule and when a fan is used. The fan will run 1-3 hours before the occupied
schedule starting time to circulate air.
Override Button, Temporary Override (Duration Limit ISU 0535): While in the programmable schedule mode, an override button is available to perform temporary override control. The default override
time can be configured through ISU 0535. Lockout configuration via ISU 0670 can provide restrictions
on access to setpoint changes, system changes, and schedule changes.
No remote setback: The remote setback feature only works in the nonprogrammable mode.
Special Non-Programmable Mode Functions
Override (Optional): The override feature is optional in the non-programmable mode. The override
can be configured through ISU 0342. When the override is activated in the non-programmable mode it
will temporarily override to a new setpoint until the end time expires.
Remote Setback: Remote Setback is available (ISU 0340). Occupancy sensors, manual time clock
inputs, and DDC night setback can be used to provide inputs to setback the thermostat. Unoccupied
heating (ISU 0343) and unoccupied cooling (ISU 0346) setpoints are available to configure the setback
setpoints.

Troubleshooting
Symptom
Possible Cause
Action
Display does not come
on.
Thermostat is not being
powered.
Check for 24 Vac between C and R. Check that AA
batteries are installed correctly and are good.
Temperature settings
do not change.
The upper or lower temperature
limits were reached.
Check temperature setpoints. Check Installer Setup
Numbers 0600 and 0610; modify as needed.
The keypad is fully locked.
Check Installer Setup Number 0670 to change
keypad locked options.
Thermostat minimum off-time is
activated.
Wait up to five minutes for the system to respond.
System selection not set to Heat
or Cool.
Set system Selection to correct position.
System type Selection is
incorrect.
Check Installer Setup Number 0170 and make sure
correct System type is chosen.
Heating equipment failure.
Check for 24 Vac at the equipment on the secondary
side of the transformer between power and
common. If voltage is not present, check the heating
equipment to find the cause of the problem.
Check for 24 Vac between the heat terminal (Y and
H2) and transformer common. If 24 Vac is present,
the thermostat is functional. Check the heating
equipment to find the cause of the problem.
Loose or broken wire
connection between thermostat
and heating equipment.
Check for 24 Vac between the heat terminal (Y
and H2) and transformer common. If voltage is not
present, check wire connection (loose or broken)
between the thermostat and the heating equipment.
Cooling equipment failure.
Check for 24 Vac at the equipment on the secondary
side of the transformer between power and
common. If voltage is not present, check the cooling
equipment to find the cause of the problem.
Check for 24 Vac between the cool terminal (Y)
and transformer common. If 24 Vac is present,
the thermostat is functional. Check the cooling
equipment to find the cause of the problem.
Loose or broken wire
