Resumen del manual
There may be more than one power disconnect. Electrical shock can cause personal injury or death. Improper wiring or installation may damage thermostat. Wiring must conform to local and national electrical codes. INSTALLATION CONSIDERATIONS The thermostat is a wall mounted, low-voltage thermostat, which maintains room temperature by controlling the operation of a heating and air conditioning system. Batteries are not required; temperature and mode settings are preserved with the power off. I. THERMOSTAT LOCATION Thermostat should be mounted: - Approximately 5 ft. (1.5m) from fl oor. - Close to or in a frequently used room, preferably on an inside partitioning wall. - On a section of wall without pipes or duct work. Thermostat should NOT be mounted: - Close to a window, on an outside wall, or next to a door leading to the outside. - Exposed to direct light and heat from a lamp, sun, fireplace, or other temperature-radiating object which may cause a false reading. - Close to or in direct airflow from supply registers and return-air grilles. - In areas with poor air circulation, (behind a door or in an alcove.) 4.55 3.30 Selects System Mode: OFF. HEAT, or COOL Increase Temperature Decrease Temperature Turns Continuous Fan On or OFF 0.8 II. INSTALL THERMOSTAT 1. Turn off all power to unit. 2. If an existing thermostat is being replaced: A. Remove existing thermostat from wall. B. Disconnect wires from existing thermostat, one at a time. Be careful not to allow wires to fall back into the wall. C. As each wire is disconnected, record wire color and terminal marking. D. Discard or recycle old thermostat. NOTE: Mercury is a hazardous waste and MUST be disposed of properly. 3. Separate the thermostat and back plate. 4. Route thermostat wires through hole in back plate. Level back plate against wall (for aesthetic value only - thermostat need not be leveled for proper operation) and mark wall through 2 mounting holes. 920-162-01 (5-05) 5. Drill two 3/16-in. mounting holes in wall where marked. (Note: Mounting holes on back plate are designed to fit on a horizontal J-box). 2.375 3.275 2.625 1.587 6. Secure back plate to wall with 2 anchors and screws provided making sure all wires extend through hole in back plate. 7. Connect wires to proper terminal of the connector block 8. Push any excess wire back into wall. Excess wire inside the thermostat plastic case can interfere with proper air fl ow across the temperature sensor. Seal hole in wall to prevent air leaks. Leaks can affect operation. 9. Install thermostat on back plate. 10. Turn on power to the unit. On initial power up, the LCD readout will display oP. WIRING DIAGRAMS NOTE: All excess wire should be pushed back into the wall as far as possible. Excess wire inside the thermostat plastic case may interfere with the air flow across the temperature sensor.

Fan Operation A. Press fan button, starting fan operation. Fan icon turns on. B. Press Fan button, stopping fan operation. Fan icon turns off. 2. Heating Operation A. Press and Release MODE button until HEAT is displayed. B. Press up button until LCD readout reads 10 degrees above room temperature. Heating system should begin to operate within 5 minutes. 3. Cooling Operation A. Press and Release MODE button until COOL is displayed B. Press down button until LCD readout reads 10 degrees below room temperature. Cooling system should begin to operate within 5 minutes. IV. THERMOSTAT OPERATION 1. TEMPERATURE DISPLAY The thermostat will display room temperature until the UP or DOWN button is pressed. The word SET appears when these buttons are pressed and the current set point is displayed. If no buttons are pressed for 5 seconds, the display will change back to show room temperature. 2. TIMEGUARD TIMER A 5-minute timeguard is built into the thermostat immediately upon power up, and any time the compressor turns off. The compressor will not turn on until the timeguard has expired. Pressing UP and FAN buttons simultaneously will override the timeguard for 1 cycle. 3. CYCLE TIMER In normal heating and cooling operation the thermostat will not allow more than 4 equipment cycles per hour (or 1 cycle every 15 minutes). Both the Y and W outputs have a 15-minute timer that starts counting down when the output is turned on, (e.g., if Y output is turned on for 9 minutes and then satisfi es, it cannot turn back on for another 6 minutes regardless of demand). However, pressing UP and FAN buttons simultaneously or changing the set point will override the timer for 1 cycle. 4. MINIMUM ON TIMER Once the equipment has turned on, it will remain on for a minimum of 3 minutes regardless of demand. However, the equipment can turn off in less than 3 minutes if a change in set point, or a change in mode occurs. 5...
