22 Removing an existing thermostat 1. Disconnect the power to the control transformer. 2. Remove the cover to the existing thermostat. 3. Disconnect the wires going to each terminal on the thermostat. Label each wire with the letter or number at the terminal. 4. Remove the existing plate or base from the wall. MOUNTING When mounting the RC-80BZ, grasp the thermostat by the sides, avoiding the keys, and unsnap the base from the face. Holding the base to the wall so that the word "TOP" is upright and facing you: 1. Mark the two mounting holes on the wall using a pencil. 2. Drill a hole using a 3/16" bit at each mounting hole marking. 3. Install the two wall anchors supplied. 4. Slide the system wires through the opening in the base. 5. Mount the base to the wall using the two #6 x 1/2" self-tapping screws supplied - See Figure 1. Figure 1
33 Connect each wire to the terminal strip on the thermostat base per the wiring diagram for your system application - See Figures 4 - 8. Form the thermostat wiring so that the cable lies flat between the terminal strip and the center of the base. Upon completion of wiring the thermostat, push all excess wiring into the hole in the wall. Plug the hole with the supplied insulating foam to ensure an accurate temperature reading by the thermostat. Align the tabs of the thermostat face with the slots of the thermostat base. Gently push the thermostat face into the thermostat base locking it into place - See Figure 2. Figure 2 Figure 3 Note: Be sure that the thermostat temperature sensor is standing up, and that it has not been damaged during installation - See Figure 3.
44 TYPICAL WIRING DIAGRAMS CAUTION: Be sure to disconnect the power to the control transformer before removing or installing thermostat. Do not short gas valve, fan, heat relay, or cool relay...even momentarily. This will blow a non-replaceable fuse. Do not attempt to hook up to live circuits. An accidental connection to a component on the thermostat circuit board could cause damage to the thermostat. Figure 4 - Thermostat power-up for test or demonstration purposes Note: As a convenience to the installer, the compressor start up protection delay can be canceled. To cancel the delay, press the Prog key 3 times, then press the Fan key 2 times. Common wire is required in “heat only” applications Figure 5 - Single stage heat only thermostat
55 Common wire is required in “cool only” applications Figure 6 - Single stage cool only thermostat * Common wire is required to use the display backlight in the RC-80ZB. Also use if heat, cool, or fan relay cannot supply 15mA to power thermostat, without activating. Figure 7 - Single stage heat/cool thermostat
66 *Do not connect RC and RH together. Figure 8 - Heating & cooling with separate transformers CONFIGURING THE BACKLIGHT ON THE RC-80ZB The backlight on the RC-80ZB can be configured to one of three different modes: 1) on for 30 seconds when a key is pressed, 2) always on, or 3) always off. 1) To configure the display backlight to turn on when a key is pressed, then back off 30 seconds later, set the “JP2” (Select Backlight Mode) jumper to the “TIMED” position (between the middle and left pin on the connector) - See Figure 9. 2) To configure the display backlight to always be on, set the “JP2” (Select Backlight Mode) jumper to the “ON” position (between the middle and right pin on the connector) - See Figure 9. 3) To configure the display backlight to never come on (always off), remove the “JP2” (Select Backlight Mode) jumper from the connector - See Figure 9. DISABLE KEYS The keys on the thermostat can be disabled to prevent anyone from controlling the thermostat locally. To disable the keys, solder a wire jumper across “JP1” (two holes on the circuit board) - See Figure 9.
77 SOLDER WIRE JUMPER HERESELECT BACKLIGHTMODE (SET JUMPER)TO DISABLE KEYS LOCALLY Figure 9 POWER UP 1. Double check wiring, be sure that there are no stray wires or wire strands at the connections. 2. Connect power to the transformer and system. The display will show all segments for about 5 seconds. 3. Press the Fan key. The fan should come on. Press the Fan key again. The fan should go off. 4. Set the Mode to "HEAT". Use the up arrow key to raise the desired temperature setting above the current temperature. Ensure that the heater unit comes on. Set the mode to "OFF". Ensure that the heat goes off. 5. Set the Mode to "COOL". Use the down arrow key to lower the desired temperature setting below the current temperature. Ensure that the cooling unit comes on. Set the mode to "OFF". Ensure that the cooling unit goes off. The RC-80BZ thermostat is designed to work with most 4-wire HVAC systems (without a transformer common). However, if the RC-80BZ “resets” (goes blank for a second…then displays all segments for about 5 seconds) when calling for heat or cool, or if the heat, cool, or fan relay cannot supply 15mA to power thermostat without the relay activating, the transformer common wire or the HAI Thermostat Power Supply Module is required. If the thermostat or system does not perform as stated above, recheck all wiring - See Troubleshooting Tips.
