Glossary of TermsGlossary of Terms

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.

After programming for all seven days is complete, press the PROGRAM button to leave the Setup screens. If no buttons are pressed, the display will leave the setup screens after 30 seconds.

If only the Occupied 1 period is selected in the first programming step (page 6.2), Occupied 2 & 3 programming steps are skipped. Furthermore, if Occupied 2 is selected, Occupied 3 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,

8am 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 24 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.

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 described above.

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

Installing the Remote SensorsInstalling the Remote Sensors

Up to eight wired or wireless remote sensors may be installed on the

thermostat (RS1) to control the temperature in other rooms. If more than one sensor is connected to (RS1) the thermostat will average the sensors to determine the displayed temperature reading. One wired or wireless remote sensor may be installed to read the outside temperature (RS2). If a sensor(s) is connected to RS1 and is programmed to control the thermostat, the degree icon on the thermostat will blink once per second to indicate that a remote sensor reading is being displayed. The wired sensor can be connected to the thermostat with up

to 150’ of 18 ga., 300’ of 20 ga., or 450’ of 22 ga. unshielded, thermostat wire. If multiple sensors are wired to the thermostat, then the

total wiring distance of the furthest sensor should be used in determining the appropriate wire gauge. The wired sensor can be connected to the thermostat using a two or three wire installation. If a two wire installation is required, then RS+5 must be connected to RSGND (see below).

This wire MUST be completely separated from the thermostat or any other control wiring and must NOT be in the same conduit as high voltage wiring.

Random Start OperationRandom Start Operation

This feature allows a 2 to 30 second delay before energizing the thermostat outputs after any of these events:

Loss of Power to the thermostat: When power to the thermostat is interrupted and then restored, Random Start will lockout the outputs of the thermostat for a random amount of time. This delay helps to keep multiple thermostats from energizing their outputs at the same time after a power outage.

Changing from an Unoccupied time period to an Occupied time period: If the thermostat is running in the Program On mode

and the start time for an Occupied period forces the thermostat from Unoccupied to Occupied 1, Random Start will lockout all outputs of the thermostat for a random amount of time. This delay helps to keep multiple thermostats from energizing their outputs at the same time each day.

Closure of the Dry Contact to force Occupied 1 time period: If step #41 (previous page) is programmed for Occupied 1, then

Random Start will lockout all outputs of the thermostat for a random amount of time when a Dry Contact closure occurs (depending on step #40). This delay helps to keep multiple thermostats from energizing their outputs each time the Dry Contact is used.

Sensing of a light source by the Light Sensor to force Occupied 1 time period: If step #42 (page 17.2) is programmed YES for Light Activated

operation, Random Start will lockout the outputs of the thermostat for a random amount of time when a light source forces the thermostat into Occupied 1. This delay helps to keep multiple thermostats from energizing their outputs each time the lights are turned on.

Adjusting the Light Sensor Adjusting the Light Sensor

The light sensor can be adjusted for variable degrees of sensitivity. The sensitivity adjustment screw is located on the side of the thermostat, as illustrated below. Turning the screw clockwise increases the sensitivity of the sensor to light.

To check for correct sensitivity, place the thermostat in the Program On mode. When the lights are on the thermostat should enter Occupied 1 and blink the Occupied 1 icon. If the thermostat does not enter Occupied 1 while the lights are on, use the supplied screw driver to turn the light sensor screw clockwise until the Occupied 1 icon appears on the display. The thermostat should enter an unoccupied period when the lights are off. If the sensor does not enter an unoccupied period when the lights are turned off, use the supplied screw driver to turn the light sensor screw counterclockwise until the Unoccupied icon appears on the display, with the lights off.

The Light Sensor Adjustment Screw is located on the side of the thermostat.

How to Use the Energy Save FeatureHow to Use the Energy Save Feature

If the thermostat is configured to be programmable (Section 4), and

Energy Save has been selected in step #43 (below), the room will attempt to reach the selected comfort temperature at the exact time programmed into the thermostat. Energy Save, or more commonly known as Smart Recovery, only works when the thermostat enters Occupied 1 from Unoccupied. For example, if the Unoccupied program is set for 6pm at 55°F heating and 85°F cooling, and the Occupied 1 program is set for 8am at 72°F heating and 75°F cooling, the thermostat will turn the system on before 8am in an effort to bring the temperature to its correct setting at exactly 8am. The P374-2900 learns from experience, so please allow 4-8 days after a program change or after initial installation to give Energy Save time to adjust to local weather, the construction of your business, and your heating and cooling system.

PROGRAMMABLE OUTPUT - SECTION 14

This jumper setting allows the MISC outputs to control a pilot relay by time, temperature, or a signal from the Internet/Phone. The following are three possible scenarios: By Time: A device that requires a start and stop time. For example, an exterior lighting system that needed to be energized every day

between the hours of 8pm and 1am. By Temperature: An exhaust fan that needs to energize whenever the temperature from RS1 rises above 90 degrees F. By Remote: Remotely arming a security system through the web or phone.

HUM JUMPER SETTING

If the jumper for MISC1, MISC2, or MISC3 is set to HUM, the corresponding MISC screw terminal on the backplate will control a humidification system.

HUMIDIFICATION OPERATION - SECTION 9

If your HVAC unit is equipped with a humidification system and the Humidity Module (sold separately) has been installed, the thermostat will provide power to the MISC1, MISC2, or MISC3 terminal of the thermostat when the humidity in the home falls below the humidity setpoint you have chosen. The value for this setpoint ranges from 0% to 60%. If no humidity is desired or if a humidification system has not been installed, set the value to 0%.

DEHUM JUMPER SETTING

If the jumper for MISC1, MISC2, or MISC3 is set to DEHUM, the corresponding MISC screw terminal on the backplate will be connected to the dehumidification terminal of a furnace board. NOTE: Not all furnaces have a dehumidification terminal.

DEHUMIDIFICATION OPERATION - SECTION 10

If your HVAC unit is equipped with a dehumidification system the thermostat will operate in one of two ways.

1) Normally Closed (NC): The thermostat will de-energize the MISC1, MISC2, or MISC3 terminal of the thermostat (this MISC terminal is connected to the DEHUM terminal on your furnace) to allow the fan to run in low speed when the humidity in the building is above the dehumidify setpoint you have chosen and there is a call for 1st stage cooling.

2) Normally Open (NO): MISC3 terminal of the thermostat (this MISC terminal is connected to the DEHUM terminal on your furnace) to allow the fan to run in low speed when the humidity in the building is above the dehumidify setpoint you have chosen and there is a call for 1st stage cooling.

The thermostat will energize the MISC1, MISC2, or

ECON JUMPER SETTING

If the jumper for MISC2 or MISC3 is set to ECON, the corresponding MISC screw terminal on the backplate will be connected to an economizer.

ECONOMIZER OPERATION - If your HVAC unit is equipped with an economizer system, the thermostat will provide power to the MISC2 or MISC3 terminal of the thermostat when the thermostat is in an occupied time period. The MISC2 or MISC3 terminal will be de-energized when the thermostat is in an unoccupied time period.

Y2 JUMPER SETTING

If the jumper for MISC1 is set to Y2 the MISC1 screw terminal on the backplate will control a second stage of cooling.

Y2 OPERATION - SECTION 13

Control up to two Cool stages.

The 2nd Stage of cool is turned on when: (A) The 1st Stage has been on for the time required (step #27, page 13.6). It is adjustable from 0-60 minutes and the default is two minutes.

And

(B) The temperature spread from the setpoint is equal to or greater than: the setpoint plus the deadband (step #24, page 13.5), plus the 2nd deadband (step #25, page 13.5). This 2nd deadband is adjustable from 0-10 degrees and the default is two degrees.
