Auto-Changeover: A mode in which the thermostat will turn on  
the heating or cooling based on room temperature demand.  
Configurable Output Jumper: Using jumpers on the thermostat  
you can configure the MISC1, MISC2, and MISC3 terminals to  
control humidification, dehumidification, 2nd stage cooling, 3rd  
stage heating, and a programmable output.  
Cool Setpoint: The warmest temperature that the space should  
rise to before cooling is turned on (without regards to  
deadband).  
Deadband: The number of degrees the thermostat will wait, once  
setpoint has been reached, before energizing heating or cooling.  
Dehumidify: To reduce the amount of moisture in the air.  
Differential: The forced temperature difference between the  
heat setpoint and the cool setpoint.  
Heat Setpoint: The coolest temperature that the space should  
drop to before heating is turned on (without regards to  
deadband).  
Humidify: To increase the amount of moisture in the air.  
Icon: The word or symbol that appears on the thermostat  
display.  
Mode: The current operating condition of the thermostat (i.e. Off,  
Heat, Cool, Auto, Program On).  
Non-Programmable Thermostat: A thermostat that does not  
have the capability of running the Time Period Programming.  
Programmable Thermostat: A thermostat that has the capability  
of running the Time Period Programming.  
Reheat: Running the cooling and 2nd stage strip heaters at the  
same time in order to dehumidify the air without cooling down  
the room temperature.  
Temperature Swing: Same as Deadband.  
Time Period Programming: A program that allows the  
thermostat to automatically adjust the heat setpoint and/or the  
cool setpoint based on the time of day.

PROGRAMMING TIPS  
If only the Occupied 1 period is selected in the first programming step (page 6.2), Occupied  
& 3 programming steps are skipped. Furthermore, if Occupied 2 is selected, Occupied 3  
2
programming steps are skipped.  
Heat & Cool setpoints for Occupied 1 are the same for every day of the week. If desired,  
Heat & Cool setpoints for Occupied 2 & 3 can be adjusted differently for each day of the week.  
If the start time is set later in the day than the stop time, the program will run from the start  
time to midnight and from midnight to the stop time on the same day. For example: 9pm start,  
8
am stop, on Monday. In this example the program will run from 12am Monday to 8am Monday  
and again from 9pm Monday to 12am Tuesday.  
Unoccupied Operation: The unoccupied settings take effect at all times when: (1) the program is  
on and (2) the current time is outside a preset occupied period. For this reason start and stop  
times are not necessary for unoccupied time periods.  
If the same start and stop times are programmed for an occupied period, then it will run  
2
4 hours.  
If one occupied period starts and stops within another occupied period the lower occupied # has  
priority. For example: If Occupied 3 is programmed to be on 24 hours, and Occupied 2 is  
programmed to run that day, then the Occupied 2 setting will take over for Occupied 3 between  
Occupied 2 start and stop times.

To install the Humidity Module the thermostat must be detached  
from the back plate. Plug the Humidity Module into the Humidity  
Module connector as shown in Figure 2 below. Follow the detailed  
instructions included with the Humidity Module accessory. Once the  
Humidity Module has been installed, you must adjust the Humidity  
jumper setting to HUM as shown in Figure 1 below. This will allow  
you to access the humidification and dehumidification setup steps.  
For proper humidity operation, this  
jumper must be set for HUM.

the humidity in the building falls below the setpoint you have chosen.

To control a MISC output for dehumidification, install the Humidity  
Module and place the Humidity Jumper on HUM (see page 9.2).  
Then place the MISC1, MISC2, or MISC3 jumper on the terminal  
labeled DEHUM (see diagram below). This will supply 24VAC to the  
selected MISC terminal based on the programming in the following  
pages. Only one of the three outputs (MISC1, MISC2, or MISC3) is  
required to have a jumper. For more information regarding the  
MISC1, MISC2, and MISC3 outputs, please see section 21.

Dehum Terminal: If a MISC terminal is selected for DEHUM operation  
(see page 10.2), then the thermostat will provide power to this terminal  
when the humidity in the building is above the setpoint you have chosen.  
See page 10.6 for detailed programming instructions. To utilize this  
feature your HVAC unit must be equipped with a DEHUM terminal.  
Cool to Dehumidify: If the thermostat is programmed for Cool to  
Dehumidify operation, then the thermostat will energize the cooling  
system any time the humidity in the building is above the setpoint you  
have chosen. The thermostat may also be programmed for Reheat  
operation if available. See pages 10.4 and 10.5 for detailed  
programming instructions.  
In each case, when the indoor humidity falls below the setpoint you  
have selected, Cool to Dehumidify and the MISC terminal will be  
de-energized. The value for this setpoint ranges from 25% to 99%.

If Cool to Dehumidify is on and the Humidity Module is installed,  
the thermostat has the ability to initiate a cooling cycle for advanced  
dehumidification operation. When the thermostat detects the humidity  
percentage is above the setpoint for dehumidification, and heating or  
cooling is not on, the thermostat will force the compressor to run with  
the fan, thus reducing moisture in the air. The green LED will blink  
once every eight seconds to indicate this is taking place. This feature  
will also allow you to adjust the cooling overshoot of the setpoint, from  
0° to 5° (adjustable in step #11). For Example: If the cooling overshoot is  
set for 3°F and the cooling setpoint is set for 74°F, then as long as the room  
temperature reads between 71°F and 74°F this feature will energize the  
compressor and fan to dehumidify the air.

is a call for 1st stage cooling and the room humidity is greater than  
the dehumidification setpoint.
