Summary of Contents

• Page 1: Big Blue Humidity Universal Thermostat with humidity/dehumidity control and automatic heat/cool changeover option. Single stage, multi-stage, heat pump installation and operating instructions. Failure to read and follow all instructions carefully before installing or operating this control could cause personal injury and/or property damage. Programming choices include 7 day, 5/1/1 day, and non-programmable options. Thermostat application guide includes configurations for gas, oil, electric, heat only, cool only, and heat/cool systems. Electrical rating: battery power from mV to 30 VAC, NEC Class II, 50/60 Hz or DC. Setpoint range is 45 to 99°F (7 to 37°C). Operating ambient temperature range is 32°F to +105°F (0 to +41°C). This product does not contain mercury, but may replace a product that does. Caution: to prevent electrical shock and/or equipment damage, disconnect electric power to the system at the main fuse or circuit breaker box until installation is complete.
• Page 2: Installation Thermostat power method Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code. Battery powered, no 24 Volt system power available. Remove old thermostat and mark wires for terminal identification. Installing new thermostat involves pulling the thermostat body off the base and marking mounting hole locations. Fasten base snugly to wall using mounting holes and two mounting screws. Connect wires to terminal block on base using appropriate wiring schematic. Push excess wire into wall and plug hole with a fire resistant material. For best results, use a premium brand AA alkaline battery. The Power Stealing Switches should be left in the On position for most systems.
• Page 3: Wiring diagrams for single stage or multi-stage systems are provided. Single stage systems use a single transformer and include various terminals for configuration. Installer configuration menu allows selection of O or B for changeover function. Fault or system malfunction indicators are included for heat pumps. A 24 volt common connection is optional for system operation. Blower/circulator fan is energized on a call for cool or fan on. Multi-stage systems can be configured for gas, oil, or electric systems. Heat pump connections are specified for both single and multi-stage compressor systems. Refer to equipment manufacturers’ instructions for specific system wiring information. After wiring, consult the installer configuration section for proper thermostat configuration.
• Page 4: Wiring diagrams provide essential information for system setup. The DHM terminal is used on systems with a compatible dehumidification feature. Humidification terminal energizes on call for heat if humidity setpoint is above room humidity. A relay should be installed to switch the fan speed to a lower speed for dehumidification. The reduction in air flow allows the coil to remove more humidity from the air. The anti-freeze-up control is recommended to prevent the air conditioning coil from freezing. Typical wiring for dehumidifier and humidifier systems is illustrated in the figures. The relay should be rated for blower motor load. Configuration menu item #34 selects humidification. The CAFC breaks the compressor circuit when the suction line drops below 38°F.
• Page 5: Thermostat quick reference provides essential information for users. Home screen displays room temperature, set temperature/humidity, day of the week, and time of day. Battery level indicator shows the current power level of the batteries. Menu key allows access to different modes such as cleaning, configuration, set time, and set schedule. Displays indicate when the thermostat is calling for heat or cool, and when the batteries should be replaced. Keypad lockout mode limits access to certain functions. Change Filter, Change Pad, and Change UV Lamp reminders appear when maintenance is due. Cool Savings feature indicates energy-saving mode status. Hold mode displays the current temperature setting and duration of the hold. Call for Service alerts users to faults in the heating or cooling systems.
• Page 6: Installer/configuration menu instructions include pressing the menu touch key and holding the installer config touch key for 5 seconds. Screen reference numbers appear in the top right corner of the display. Shaded items are not available if selected for non-programmable.

Keep guidelines in mind when planning your program for energy savings.
• Page 14: Programming worksheet for re-programming 5+1+1 and 7 day program. Heating program includes settings for wake up, leave for work, return home, and go to bed. Cooling program also includes settings for wake up, leave for work, return home, and go to bed. Wired remote temperature sensing allows the thermostat to display temperature from either the thermostat or remote sensor. One remote temperature sensor can be installed indoors or outdoors and connected to the thermostat. The thermostat must have a 24 VAC common connection for the remote sensor to operate. The remote sensor can be enabled or disabled in the installer/configuration menu. When enabled, the display alternates between time and remote temperature. The remote sensor can be set as indoor or outdoor. Outdoor temperature range is -40°F to 140°F; indoor temperature range is 32°F to 99°F.
• Page 15: Programming Averaging or weighting remote sensors The thermostat will weight or average the temperature of the indoor remote sensor with the local sensor in the thermostat for each program period. When the thermostat is configured for Heat Pump mode and the Dual Fuel feature is selected on, the thermostat can monitor the outside temperature using remote sensor F145-1378. The user selectable temperature is called the dual fuel temperature setpoint, dF, and is set in the Installer/Configuration menu. With outdoor remote sensor installed and enabled, the dual fuel temperature setpoint can be set to a temperature of -5° through 50°. A higher temperature or dual fuel setting will provide a smaller stage separation between the heat pump and Aux to give more comfort. In normal operation of the thermostat, the current temperature displayed will be the weighted average of the local sensor and the remote sensor. Blower balance point for heating allows you to select an outdoor temperature to slow the fan speed so the air from the duct feels warmer. Comfort Alert Codes The Comfort Alert diagnostics product monitors the air conditioning outdoor systems with single phase Copeland Scroll compressors. Abnormal system and electrical conditions are indicated by flashing ALERT codes on the yellow LED on the Comfort Alert module.
• Page 16: Troubleshooting Reset operation: If a voltage spike or static discharge causes erratic thermostat operation, reset the thermostat by removing it from the wall plate and taking out the batteries for 2 minutes. Common problems: No heat, no cool, or no fan can be caused by a blown fuse, tripped circuit breaker, or loose connections. No heat: Possible causes include an unlit pilot light, furnace lock-out condition, or the need for service or thermostat replacement. Diagnostic for no heat: Set the system switch to heat and raise the setpoint above room temperature. A soft click indicates proper operation. No cool: Similar diagnostic steps as no heat, but set the thermostat to cool and lower the setpoint below room temperature. Constant running: Possible wiring shorts or incorrect fan switch settings may cause the heat, cool, or fan to run constantly. Thermostat setting disagreement: The thermostat thermometer setting can be adjusted by +/- 4 degrees. Cycle rate issues: The location of the thermostat or the size of the heating system may influence the cycle rate. Adjust settings in the configuration menu if necessary. Forgot keypad lockout code: Press and hold the menu key for 20 seconds to unlock the thermostat. Blank display: A voltage spike or static discharge may require a reset operation.
