IMPORTANT: Read entire instructions before programming the
thermostat.
GENERAL
The 7-day, commercial, programmable thermostats are wall-mounted, low-
voltage thermostats which maintain room temperature by controlling the op-
eration of an HVAC (heating, cooling and ventilation) system. Separate heat-
ing and cooling set points and auto-changeover capability allow occupied
and unoccupied programming schedules for energy savings.
All thermostats allow up to 3 occupied and one unoccupied time/
temperature setting to be programmed per 24-hour period. Each thermostat
stores programs for 7 independent days. Batteries are not required. During
power interruption the internal NEVERLOST™ memory stores programs for
an unlimited time.
IMPORTANT: The thermostat has a configurable security level. If certain
functions are not available (changing set points, changing programming
schedules), the thermostat security level may be configured to exclude those
functions. Call the installer to reconfigure the security level.

the fan will run during heating and cooling operation only.
MODE BUTTON OPERATION — The Mode button selects the operating
mode of the thermostat. If OFF is selected, the thermostat will not enter Heat-
ing or Cooling mode. If HEAT is selected, the thermostat will only enter
Heating mode (if the room temperature is below the heating set point). If
COOL is selected, the thermostat will only enter Cooling mode (if the room
temperature is above the cooling set point). If AUTO is selected, the ther-
mostat will enter Heating or Cooling mode based on the room temperature
and the heating and cooling set points. If PROGRAM ON is selected, the
stored schedule is enabled and the thermostat will follow the Occupied and
Unoccupied schedules stored in its memory.
Auto-Changeover — When the thermostat mode is set to AUTO, the ther-
mostat will provide automatic changeover from heating to cooling mode and
cooling to heating mode when required. The thermostat will automatically
switch to maintain the desired temperature setting. The thermostat does not
need to be manually changed from heating to cooling or cooling to heating
operation.

OPERATION
The Mode button selects the operating mode of the thermostat. If OFF is
selected, the thermostat will not enter Heating or Cooling mode. If HEAT is
selected, the thermostat will only enter Heating mode (if the room tempera-
ture is below the heating set point). If COOL is selected, the thermostat will
only enter Cooling mode (if the room temperature is above the cooling set
point). If AUTO is selected, the thermostat will enter Heating or Cooling
mode based on the room temperature and the heating and cooling set points.
If PROGRAM ON is selected, the stored schedule is enabled and the ther-
mostat will follow the Occupied and Unoccupied schedules stored in its memory.
Auto-Changeover — When the thermostat mode is set toAUTO, the ther-
mostat will provide automatic changeover from Heating to Cooling mode
and Cooling to Heating mode when required. The thermostat will automati-
cally switch to maintain the desired temperature setting. The thermostat does
not need to be manually changed from heating to cooling or cooling to heat-
ing operation.
Two-Stage Operation — The second stage of heat or cool is turned on
when the first stage has been on for a minimum of 2 minutes and the tem-
perature differential from the set point is equal to or greater than the set point
plus the deadband plus 2 degrees.
Clock Backup — In the event of a power loss, the thermostat will keep
time for a minimum of 48 hours without external power or batteries.
Fan Operation — If Fan On is selected, the fan will run continuously
during occupied schedule (except when Mode is switched to OFF). The fan
will be off during unoccupied schedule except during heating or cooling
operation.
If Fan On is not selected, the fan will only operate during heating or cool-
ing operation.
Emergency Heat — Emergency heat is available for heat pump applica-
tions. To turn on emergency heat, press and hold the Fan button. While hold-
ing the Fan button, press the UP button for 2 seconds. An ‘‘EH’’ will be dis-
played. During emergency heat, the fan will operate and the second stage of
heat will be energized (locking out the first stage compressor). To exit emer-
gency heat, press and hold the Fan button. While holding the Fan button,
press the UP button for 2 seconds. During emergency heat, only OFF and
HEAT modes are available.

Electric Heat — When the Electric Heat option in the advanced set up is
set to ON (configured by installer), the thermostat will turn on the fan im-
mediately any time there is a heat demand. This feature should only be used
on electric heating applications. Do not use with gas heat.
Holiday Mode — When the thermostat is in Holiday mode, the thermostat
will operate under Unoccupied set points. To configure and activate the Holi-
day mode, press the Holiday button. The ‘‘HOL’’icon will be displayed along
with the remaining days of Holiday mode operation. Press the UP or DOWN
ARROWS to select the number of days that the holiday schedule will be in
effect. A value of 0 disables Holiday mode. The duration can be set from 1
to 99 days. The thermostat will enter Holiday mode on midnight of the next
day after the mode has been activated. Holiday mode will remain in effect
until midnight of the last configured day.
If the Holiday mode is in effect, the number of days remaining will blink
on and off and the ‘‘Unoccupied’’ icon will be displayed. The Override but-
ton will be active during Holiday mode. The Dry Contact Switch is ignored.
To turn off the Holiday mode before the remaining configured days have
passed, press the Holiday button to enter into the configuration mode. Press
the DOWN ARROW to set the number of days to zero. Holiday mode will
be disabled.
Dry Contact Switch/External Device — A dry contact switch is pro-
vided to allow an external device to force the thermostat into Occupied 1.
When the thermostat is forced into Occupied 1 via the dry contact closure,
the Occupied 1 icon will blink each second.
SOFT START — When multiple thermostats are controlled by the same ex-
ternal device, a Soft Start option can be used to stagger the turn on times of
the HVAC equipment. This feature may cause a delay in operation after en-
tering Occupied 1.
Remote Temperature Sensor — A remote temperature sensor is avail-
able to read the temperature from a space. If a remote temperature sensor is
connected, the thermostat will ignore the reading of its internal sensor. When
the thermostat is using a reading from a remote sensor, the degree symbol
above the temperature reading will blink.
