Pre-Installation

This section provides the following pre-installation information:

• Location considerations

• Height requirements

• Mounting surfaces

• Maximum wire length

Location Considerations

When selecting a location, avoid the following:

• Areas of direct sunlight

• Areas in the direct airstream of air diffusers

• Exterior walls and other walls that have a temperature differential between the two sides

• Areas that are close to heat sources such as sunlight, appliances, concealed pipes, chimneys, or other heat-generating equipment

• Drafty areas

• Dead spots behind doors, projection screens, or corners

• Walls that are subject to high vibration

• Areas with high humidity

• High traffic areas (to reduce accidental damage or tampering)

Height Requirements

It is recommended that you mount the back plate a maximum distance of 54 in. (137 cm) above the floor. If a parallel approach by a person in a wheelchair is required, reduce the maximum height to 48 inches.

Note: Consult section4.27.3 of the 2002 Americans withDisabilityAct guideline, and local building

codes, for further details regarding wheelchair requirements.

Mounting Surfaces

The thermostat can be mounted to any sturdy, vertical surface. Plastic threaded anchors and

M3.5 x 20 mm screws are provided for mounting to plaster or wallboard; 6-32 x 3/4 inch machine screws are provided for mounting directly to a standard electrical device box. Other fastener varieties may be required for other surface types.

When replacing a horizontally mounted thermostat and there is an adapter kit available to cover

any opening in the wall. Contact your localTrane office for more information.

Pre-Installation

Maximum Wire Lengths

Thermostat to HVAC Equipment

The thermostat may not function properly if the total resistance of any of the thermostat to HVAC

equipment wires exceeds 2.5 ohms.To ensure that wire length does not cause excess resistance, refer to long.

Table 1. MaximumThermostat to HVAC Equipment Wire Lengths

Remote Sensor to ProgrammableThermostat

Because remote temperature sensors measure resistance, very long cable runs can cause slight errors in the measurement. For the highest temperature reading accuracy, avoid exceeding the maximum recommended wire lengths shown in

Table 2. Maximum Recommended Remote SensorWire Length

Table 1 and ensure that the wires from the thermostat to the HVAC equipment are not too

Copper wire size Maximum recommended wire length

22 AWG (0.33 mm2) 150 ft (46 m)

20 AWG (0.50 mm2) 240 ft (73 m)

sensor wire length

Table 2.

Note: For 22 AWG (0.33 mm2) copper wires, the rate of error can be up to 0.5 °F (0.3 °C) per 100 ,

which typically requires wire lengths in excess of 5000 ft (1500 m).

Operation

Scheduling

The thermostat can be configured for two periods (day and night) or four periods (morning, day,

evening, and night).The chosen number of periods are applied to each day of the week when you program the thermostat. Each period canhave a unique start time, heat setpoint, cool setpoint, and fan setting.

The groups of days can be one of the following:

• 1 day = all 7 days of the week follow the same schedule.

• 5+1+1 days = Monday - Friday all follow the same schedule; Saturday and Sunday each follow their own schedules.

• 5+2 days = Monday - Fridayall follow the same schedule;Saturday and Sunday follow thesame schedule, which is different than the Monday - Friday schedule.

• 7 days = Each day follows its own schedule.

Note: See “Configuration,” p. 26 tochange the number of periods in a day or the grouping ofdays

in the schedule.

If needed, you can use Table 9 to write down your schedule settings before you begin setting up the schedule.The default schedule is also shown in the table. Unless you program your own schedule settings, the thermostat follows the default schedule for all days of the week.

Day-to-Day Operation

After a programmable thermostat is configured and the schedule is programmed, the thermostat

automatically changes the setpoints and fan settings accordingto theschedule.However,there are some operator tasks that you may need or want to perform:

• Show setpoint or current temperature.You can temporarily or permanently switch the main display from current temperature to temperature setpoint. See

Temperature on Display,” p. 39

• Set the system mode, which includes turning the system on or off, and switching between heating,

• Override the schedule. If an unexpected, one-time temperature setpoint or fan mode change is needed you can temporarily override the schedule. See “Timed Override (TOV) Mode,” p. 40.

• Lock or unlock.You can lock the thermostat buttons to prevent changes to the thermostat set

Note: It is possible for a programmable thermostat to be configured to be a non-programmable

Operational and Programming Reference Information

This section provides additional information that may be useful for understanding thermostat

operation or programming.

Deadband

The thermostat automatically maintains a temperature deadband between the heating setpoint

and the cooling setpoint whenever automatic changeover (heat-to-cool or cool-to-heat mode) is enabled.The temperature range of the deadband is 2–9 °F (1.0–4.5°C) and is specified in the installation configuration options (see temperature setpoint to within the deadband of its opposing setpoint, the opposing setpoint will automatically be pushed to the next value that satisfies the deadband. (See

Heat and Cool Cycling Rate

The heat and cool cycling rate, expressed in cycles per hour (CPH) indicates how often heating or

cooling system is turned on when temperature is within the temperature differential from the setpoint, which is 1°F (0.5°C).There are ten options (1–10) for heat stages and five options (1–5) for cool stages.The number selected is the maximum number of times the stage is cycled in 1 hr.

For example, when the system is set to 5 CPH, it runs at 12 min cycles with variable duty cycle. Depending on the heating or cooling load, which is measured by feedback from the sensor thermistor and/or temperature error, the system could run at 50% duty cycle (6 min ON and 6 min OFF), 80% duty cycle (9.6 min ON and 2.4 min OFF), or other variations of the duty cycle.

Note: The

cycling rate described above is only active when the temperature is within the temperature differential. If the temperature is outside of the temperature, the heating and cooling equipment will either be fully on or fully off accordingly. (See

“Configuration,” p. 26). If you attempt to change a

Configuration and Programming Retention

The thermostat retains the time and date for a minimum of 5 days with no electricity. If power is

lost for more than 5 days, you will need to reset the time and date when power is restored.

All configuration parameters, system settings, and scheduling are stored in non-volatile memory,

which will retain the data indefinitely with or without power.

Note: You canmanually revert todefault settings bysetting the appropriateinstallation parameter

(#300 for programmable thermostats or #18for non-programmable thermostats)to avalue of 1, and exiting configuration mode.

Extended Fan-onTime (Heat or Cool)

Note: This feature applies only to the programmable thermostat.

When the thermostat fan is in Auto mode, the fan on time can be extended.

• Configuration option #270 extends the fan on time by 90 sec after heat turns off.

• Configuration option #271extends the fan on time by 40 sec after cool turns off.

These options may not be available for some system configurations. See

Compressor and Auxiliary Heat Lockout

Note: This feature applies only to the programmable thermostat.

Compressor and auxiliary heat is used for heat pump systems with more heat stages than cool stages. When the temperature from an outdoor sensor is

• above the auxiliary lockout point, only the compressor will operate on a call for heat.

• below the compressor lockout point, only the auxiliary heat will operate on a call for heat.

• between the compressor and auxiliary lockout point, the compressor and auxiliary heat will operate on a call for heat.

There is a minimum 5°F (2.5°C) deadband between compressor and auxiliary heat lockout

temperatures. Configuration option #220 sets the compressor lockoutpoint; #221 sets the auxiliary lockout point. See

“Configuration,” p. 26.

Auxiliary Heat Control

Note: This feature applies only to the non-programmable 3-Heat/2-Cool thermostat.

You can set the auxiliary heat control using configuration option #17 to one of two settings:

• Comfort - prioritizes comfort over economy. Raising the temperature just a few degrees often will activate the auxiliary heat.

• Economy - attempts to reach the temperature setting without activating the auxiliary heat.

Economizer/TOD

Note: This feature applies only to the programmable thermostat.

You can set the Economizer orTOD mode using configuration option #150 to one of two settings:

• Economizer Mode - “A” terminal is energized with the thermostat in Occupied mode, Unoccupied mode with a call for cool, or aTimed Override mode (TOV) active.

• TOD Mode - “A” terminal is energized with thermostat in Occupied mode or aTimed Override mode (TOV) active.
