This section provides general descriptive and procedural information intended for typical daily operators of the thermostat.

Icon Descriptions

Figure 36 describes the icons visible on the front of the thermostat.TRANE-1H-1C(p-n X13511535-01)-Programmable-Thermostats-fig.01
Note: Except when the thermostat is powering up, when all of the icons are shown for 2 sec, only some of the icons will be visible at once.

Overview of Operation

If configured properly, both programmable and non-programmable thermostats will control HVAC equipment to maintain room temperature automatically

Non-ProgrammableThermostats

Non-programmable thermostats do not have timekeeping or scheduling capabilities.They will continue to maintain heating and/or cooling setpoints until an operator makes changes to the setup.Therefore, only the following tasks may be required performed:

  • Change the system mode.
  • Show or change the heating or cooling temperature setpoint.
  • Change the fan mode.

Note: The system mode, temperature setpoints, and fan mode can each be individually locked to prevent users from changing them. If you see a on the display, you may need to unlock the setting before you change it (see “Locking or Unlocking Modes,” p. 40).
Changing the System Mode
Note: If you are unable to change the system mode, check the system type setting and the manual/auto changeover setting (see “Configuration,” p. 26) to verify that the thermostat is configured with heat and cool modes, and that it permits manually changing them.
Depending upon the model and system type, the thermostat can be set to one of five modes: Cooling, Heating, Emergency Heat, Auto, or Off.

  • Cooling mode cools the room to bring it down to the cooling setpoint.
  • Heating mode heats the room to bring it up to the heating setpoint.
  • Emergency Heat mode heats the room according to the heating unit’s emergency heat mode settings.
  • Auto mode switches automatically between heating and cooling modes as required.
  • Off mode prevents the thermostat from requesting any heating or cooling regardless of the room temperature. Off mode also disables fan selection and prevents the user from changing the setpoint.

Note: The 1-Heat/1-Cool thermostat does not have Emergency Heat mode.

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 can have 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 – Friday all follow the same schedule; Saturday and Sunday follow the same schedule, which is different than the Monday – Friday schedule.
  • 7 days = Each day follows its own schedule.
    Note: See “Configuration,” p. 26 to change the number of periods in a day or the grouping of days 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 according to the schedule.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 the current temperature to the temperature setpoint. See “Showing the Setpoint or The temperature on Display,” p. 39.
  • Set the system mode, which includes turning the system on or off, and switching between heating, cooling, and automatic heating and cooling. See “Changing the System Mode,” p. 34.
  • 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 settings. See “Locking or Unlocking Modes,” p. 40.

Note: It is possible for a programmable thermostat to be configured to be a non-programmable thermostat. If installation configuration option #140 is set to 0, schedule programming capabilities will be absent.
Showing the Setpoint temperature on Display
Depending upon the value of configuration option #210, the large numeric display could show any of the following:

Timed Override (TOV) Mode
During normal operation, the thermostat controls the HVAC equipment according to the schedule that is programmed into it.To permanently change the temperature setpoint or fan setting, make the change in the programmed schedule (see “Scheduling,” p. 36). However, a timed override can be used to temporarily change the current settings without making any change to the schedule.

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 “Configuration,” p. 26). If you attempt to change a 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 Figure 38.)
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 Figure 38.)TRANE-1H-1C(p-n X13511535-01)-Programmable-Thermostats-fig.022

There is one cycling rate setting for each of the thermostat’s available heat and cool stages, including auxiliary and emergency heat stages.You can specify them during installation configuration. See “Configuration,” p. 26.

Minimum Compressor OffTime

To protect the compressor from cycling too frequently, there is an automatic 5 min gap between cycles.You cannot reduce the gap, but you can add up to 5 min if needed. See “Configuration,” p. 26.
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 can manually revert to default settings by setting the appropriate installation parameter (#300 for programmable thermostats or #18 for non-programmable thermostats) to a value 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 options #271 extends the fan on time by 40 sec after cool turns off.
    These options may not be available for some system configurations. See “Configuration,” p. 26.

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 lockout point; #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 options #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 a thermostat in Occupied mode or aTimed Override mode (TOV) active.

Troubleshooting

This section describes troubleshooting for the thermostat.
Error Codes
An error code indicates that technical assistance may be required.
Try cycling the power to the thermostat as a first method to clear the error. See Table 10 below and Table 12, p. 47 for additional information.

Problem Solution
Error code E0 – Thermistor error. •  For non-programmable thermostats and programmable thermostats set to use internal temperature sensor (configuration option #210 set to 0, 1, or 2):

Thermistor is defective or local temperature is out of range. Replace or repair thermostat through a qualified Trane supplier.

•  For programmable thermostats with configuration option #210 set to 3:

Check the sensor terminals S1 and S2 for secure connection. If wires are securely connected, try replacing the sensor.

Error code E4 – Input voltage out of range •  Check the input voltage to the thermostat. It must be within the range of 18Vac to 32 Vac rms.
Error codes E3, E5, or E7 •  Cycle the power to the thermostat.

•  If it does not recover to normal operation, have it serviced or replaced by a qualified Trane supplier.

Blank display •  Check the power supply.

•  If the power supply is ok, have the thermostat serviced or replaced by a qualified Trane supplier.

Erratic display appearance or contrast •  Check the power supply.

•  Check the frequency configuration (Configuration option #210 for the programmable thermostat or #11 for non-programmable thermostats) to make sure that you are using the correct frequency setting for your power supply.

•  If the power supply and frequency setting are ok, have the thermostat serviced or replaced by a qualified Trane supplier.

Buttons do not respond •  Make sure the thermostat modes are not locked. See “Locking or Unlocking Modes,” p. 40.

•  Cycle the power to the thermostat.

•  If the modes are not locked and cycling the power do not solve the problem, have the thermostat serviced or replaced by a qualified Trane supplier.

“–F” or “–C” flashes •  Temperature is outside of the measurable range. The temperature reading should be correct when the temperature is within the measurable range.
Fan settings are not visible •  Check the system status. If the status is Off, the fan settings will not appear.

•  Check the configuration options to verify that the fan is enabled: For programmable thermostats, check options 0130 and 0151; For non-programmable thermostats, check options 01 and 03.
