White-Rodgers 1F83-277 Heating & Air Conditioning Auto Changeover Heat Pump Thermostat User Manual Overview

Summary of Contents

• Page 1: Heating & air conditioning non-programmable, auto changeover, multi-stage/heat pump thermostat installation instructions. Failure to read and follow all instructions carefully before installing or operating this control could cause personal injury and/or property damage. Assemble tools required for installation. Disconnect electric power to the system at the main fuse or circuit breaker box until installation is complete. Label each wire with the terminal designation it was removed from before removing wires from the old thermostat's switching sub-base. Remove the old thermostat by loosening all captive screws and unscrewing the mounting screws that hold it on the wall. This product does not contain mercury, but may replace a unit which does. Disconnect the wires from the old thermostat one at a time, ensuring they do not fall back into the wall. Mercury must not be discarded in household trash; refer to the appropriate disposal guidelines for products containing mercury. Install the new thermostat using the specified procedures.
• Page 2: Mounting and wiring Take care when securing and routing wires so they do not short to adjacent terminals or rear of thermostat. Do not use on circuits exceeding specified voltage. Remove the packing material from the thermostat. Gently pull the cover straight off the base. Connect wires beneath terminal screws on base using appropriate wiring schematic. Thermostat installation and all components of the system shall conform to Class II circuits per the NEC code. Fasten base loosely to wall using two mounting screws. Leveling is for appearance only. This thermostat is configured from the factory to operate a heat/cool, fossil fuel forced air system. 2 “AA” alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage. If “BATT” is displayed, the batteries are low and should be replaced. All wiring diagrams are for typical systems only. Refer to equipment manufacturers’ instructions for specific system wiring information.
• Page 3: Wiring diagrams must observe polarity to avoid equipment damage. The accessory relay scheme is required when safety circuits exist in both systems. Two commons must be jumpered together in the wiring setup. Refer to equipment manufacturers' instructions for specific wiring information. This thermostat is designed to operate a single-transformer system. You can configure the thermostat for various heat pump system types. The 24 volt neutral connection to terminal C on the thermostat is not required if batteries are replaced annually. Typical wiring diagrams illustrate configurations for two transformer heat pump systems and single transformer multi-stage systems. Ensure proper thermostat configuration after wiring. Limit or safety switches are critical components in the system wiring.
• Page 4: Multi-stage terminal outputs require specific wiring information from equipment manufacturers. For a two-transformer system, remove the transformer from the system without safety circuits and jumper the two commons together. The thermostat can be configured for either multi-stage electric heat or multi-stage gas systems. In electric heat configuration, the G terminal will be energized on a call for heat. Refer to the terminal output information for proper wiring of the thermostat. The thermostat is designed for a single-transformer system; cut and tape off terminals for a two-transformer system. Emergency mode bypasses the heat pump to use the heat source wired to terminal E. To prevent static discharge, touch the side of the thermostat before pressing any keys. If the system does not operate properly during testing, contact a qualified service person. Do not operate the cooling system if the outdoor temperature is below 50°F.
• Page 5: Operation Before programming your thermostat, familiarize yourself with its features and the display. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, pull it straight out from the base. To replace the cover, line up the cover with the base and press until it snaps onto the base. The display shows various icons indicating the system's mode, such as HEAT and COOL. FAULT will be displayed when there is a malfunction in the system. The display indicates when the batteries are low with BATT. The configuration menu allows you to set certain thermostat operating characteristics. You can configure the thermostat for single stage, multi-stage, or heat pump operation. The factory default setting for cycle selection is fast cycle.
• Page 6: Configuration menu instructions are provided for setting up the system. Press the SYSTEM button until OFF is displayed to access the installer/configuration menu. Select single stage, multi-stage, or heat pump system configuration. Choose fast or slow cycle selection for the system. Compressor lockout can be set to OFF or ON to protect the compressor from short cycling. Backlight display can be selected to improve visibility in low lighting conditions. Fast second stage can be enabled or disabled based on temperature adjustments. Filter replacement run time can be selected in increments of 50. Temperature display can be adjusted to Fahrenheit or Celsius. Keypad lockout options are available to secure the system settings.
• Page 7: Select filter replacement run time – The thermostat will display FLTR after a set time of operation. This is a reminder to change or clean your air filter. Keypad Lockout – This menu selection will display a lock icon and “OFF” (default, keypad not locked out). Select Temperature Display Adjustment 4 LO to 4 HI – Allows you to adjust the room temperature display up to 4° higher or lower. Select F° or C° Readout – Changes the display readout to Centigrade or Fahrenheit as required. Selected Auto mode – This control will feature AUTO changeover mode when AU on is selected (default). Limited Heat Range – This feature provides a maximum setpoint temperature for heat. The default setting is 90°F. Limited Cool Range – This feature provides a minimum setpoint temperature for cool. The default setting is 45°F. Electrical Rating: 20 to 30 VAC 50/60 Hz or DC. Setpoint Temperature Range: 45°F to 90°F (7°C to 32°C). Operating Ambient Temperature Range: 32°F to 105°F.
• Page 8: Operation The system mode is selected by pressing the SYSTEM button. Icons on the bottom right corner of the display will indicate the mode: COOL, AUTO, HEAT, EMER, or OFF. In AUTO mode, the heat setpoint temperature cannot be the same as or higher than the cool setpoint temperature. When the thermostat is in AUTO mode, both the flame and snowflake icons are displayed. If the room temperature raises above the HEAT setpoint and a call for cool is required, the temperature displayed will change to the COOL setpoint. Low battery indicator will display LO BATT when the batteries are low and should be replaced. You cannot program with low batteries, but you can override setpoint temperature. After LO BATT has been displayed for 4 weeks, the thermostat will adjust temperatures automatically. Your thermostat is designed to determine the optimum time to activate the second stage. If a voltage spike or static discharge causes erratic thermostat operation, you can reset the thermostat.
• Page 9: Troubleshooting Heating system requires service or thermostat requires replacement. Diagnostic: Press SYSTEM button to HEAT and raise the setpoint above room temperature. If the thermostat does not click, try the reset operation. If the thermostat clicks, contact the furnace manufacturer or a service person. Cooling system requires service or thermostat requires replacement. Check each wire connection to verify they are not shorted or touching together. Digital thermostats normally provide precise temperature control and may cycle faster than older mechanical models. The location of the thermostat and/or the size of the heating system may be influencing the cycle rate. Thermostat thermometer setting requires adjustment. Blank display and/or keypad not responding.
• Page 10: Troubleshooting Possible cause Corrective action Symptom Forgot keypad Lockout code This resets the thermostat to factory default settings of the configuration menu. Your thermostat is designed to determine the optimum time to activate the second stage. There is a time delay from 0-30 minutes depending on the performance of the first stage of the system. Your thermostat display can be set to display temperature in Fahrenheit or Celsius. My display light does not work. Can it be fixed or replaced? When the thermostat compressor time delay occurs it will flash the setpoint for about five minutes. My setpoint temperature is flashing. What does that mean?
