Press

PROGRAM After programming for all seven days is complete, press the PROGRAM button to

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.

The OVERRIDE button may be used to interrupt the normal time

schedule programming of the thermostat. Override may only be used

when the thermostat is running the time schedule, in Program On

mode.

Unoccupied Operation - During programmed, unoccupied

periods, pressing the OVERRIDE button will temporarily

force the thermostat into Occupied 1 comfort settings for 30

minutes. The remaining Override time will alternate with the

clock (refer to the second display below). The Override timer

can be set up to a maximum of four (4:00) hours, in increments

of 30 minutes. If the timer has been set for the maximum time,

the next press of the OVERRIDE button will reset the timer,

returning the thermostat to the correct time period program for

the day.

Occupied Operation - During programmed, occupied periods, a

press of the OVERRIDE button will force the thermostat into an

unoccupied period for the remainder of the day. During this

forced unoccupied period the OVERRIDE button will operate as

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.

to the appropriate terminal on the backplate of the thermostat when

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

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.
