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 Table 1 and ensure that the wires from the thermostat to the HVAC equipment are not too long.
Installation This section provides installation instructions. Before you begin, read through the pre-installation information, beginning on 9, and also verify the following conditions are met: • A wire access hole is available at the thermostat location. • The wires are accessible through the hole. •...
To wire the thermostat: 1. Connect the wires to the terminal block(s) packaged in the box with the thermostat. (The programmable thermostat has two terminal blocks, the non-programmable thermostats have only one): • Remove approximately 1/4 inch (6 mm) of insulation from the wires.
Installation 2. Align the pins on the circuit board with the holes on the bottom of the terminal blocks and gently push the wired terminal blocks into place on the circuit board. See Figure Figure 5. Attaching the wired terminal blocks to the pins on the circuit board Programmable thermostat 3-Heat/2-Cool thermostat 1-Heat/1-Cool thermostat...

Operation Non-Programmable Thermostats 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.
5 sec to save and exit. Programmable Thermostats Programmable thermostats contain all of the functionality of the non-programmable thermostats, but they also keep track of the date, day of week, and time of day for scheduling purposes. Programming This section describes how to program the thermostat after it has been installed and configured.
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 can have a unique start time, heat setpoint, cool setpoint, and fan setting.

It returns to normal operating mode if no buttons are pressed for 45 sec.To manually exit schedule change mode, press and hold for 2 sec.
Operation 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: •...
Operation 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).
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, ”...
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.
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.
