The W8665A Receiver is used for single-zone applications.
The W8665E RF Zone Panel is used for up to three T8665A Thermostats for multi-zone applications. IMPORTANT Be sure the thermostat is at least five feet away from the W8665 during setup. Single Zone Applications (1 W8665A/1 T8665A) 1. Power up the W8665A and install the batteries in the T8665A Thermostat. 2. Place the W8665A Zone 1 DIP switch to the On position. W8665A,E RF RECEIVER MODULE d. Use Fan key to turn off fan. NOTE: At any time, if you want to stop the thermostat from sending signals to the W8665 Receiver, turn the DIP switch to Off. Then repeat steps 4 and 5 to set up the thermostat to send signals to the W8665 Receiver. 6. Repeat steps 4 and 5 for zones two and three. 7. Set System and Fan keys to desired locations. 8. Attach the zone number sticker, included with the thermostat, onto the thermostat case on the inside of the thermostat cover. See Fig. 5. Z o n e 3 Z o n e 2 Z o n e 1 Place one label inside each thermostat door. M13426 NOTE: The W8665A Zone 1 LED will flash. Fig. 5. Zone number stickers for inside of thermostat cover. 3. Press the thermostat Fan On key:
a. The receiver accepts the message and stores the identity. b. The zone 1 LED stops flashing. c. The thermostat is now set to send signals to the W866A Receiver. NOTE: The word, On, and a fan blade appear in the thermostat display to indicate the thermostat is calling for the fan to turn on. d. Use Fan key to turn off fan. 4. Set System and Fan keys to the desired locations. NOTE: At any time, if you want to stop the thermostat from sending signals to the W8665 Receiver, turn the DIP switch to Off. Then repeat steps 1-
3 to set up the thermostat to send signals to the W8665 Receiver. Multizone Applications (1 W8665E/Up to 3 T8665A) 1. Power up the W8665 and install the batteries in the 2. Set the thermostats so no zones are calling for sys-
T8665 Thermostats. tem or fan. 3. Set up each zone separately to ensure that a unique address is used for each zone. 4. Place the zone 1 DIP switch on the W8665E Receiver to the On position. NOTE: The W8665E zone 1 LED will flash. 5. Press the thermostat Fan On key:
a. The receiver accepts the message and stores the zone identity. b. The zone 1 LED stops flashing. c. The thermostat is now set to send signals to the W8665E Receiver. OPERATION W8665A Sequence of Operation On a call for heating or cooling, the thermostat sends a signal to the W8665A to bring on the heating or cooling until the call is satisfied. The Comm LED flashes when the W8665A receives a signal from the thermostat to turn on the system or approximately every ten minutes as a status update. On a call for heating, cooling or fan, the zone LED lights red. W8665E Sequence of Operation On a call for heating or cooling from any zone, the thermostat sends a signal to the W8665E to bring on the heating or cooling in that zone until the call is satisfied. The Comm LED flashes when the W8665E receives a signal from the thermostat in any zone to turn on the system or approximately every ten minutes as a status update. On a call for heating, cooling or fan, the zone LED lights red. W8665E Single and Multi-Stage Operation The first stage is energized by the thermostat. To control multistage conventional and heat pump systems, the W8665 must be wired to a zone control panel that is able to control multiple stages of heat and/or cool (such as the TZ-3 TotalZone Zone Control Panel). The zone panel (not the RF panel) controls these stages based on the number of zones calling or with a timer. See the Zone Control Panel Instructions for more details on how to control up to three stages of heat and two stages of cool. NOTE: The word, On, and a fan blade appear in the thermostat display to indicate the thermostat is calling for the fan to turn on. 5 69-1534-1

LED LED action Meaning Comm Flashes rapidly for 2-3 seconds. Indicates device is currently receiving information from the T8665 Thermostat. Zones 1-3 On constantly. Indicates system (heat, cool, or fan) is on. Zones 1-3 Off constantly. Indicates system (heat, cool, or fan) is off. Zones 1-3 Flashes rapidly until signal is received. Indicates zone is being set up to receive signals from a transmitter (T8665 Thermostat). Zones 1-3 Flashes continuously. Indicates a problem receiving signals from the transmitter

= cool) is showing in Communication is not being completed. Cooling load at W8665 is not connected correctly. End and repeat the call for heat. Check the Comm LED and Zone LED on the W8665 while the call is being made. If the Comm LED does not flash when thermostat first calls for equipment, turn that zone DIP switch to Off. Refer to Setup section to reset the W8665. If the Zone LED flashes continuously, turn that zone DIP switch to Off. Refer to Setup section to reset the W8665.
Check if 24 Vac is present:
Check between R and C on W8665.
Check between W of troubled zone and C on W8665. If voltage is present, troubleshoot heating system. End and repeat the call for cool. Wait five minutes for the compressor delay to end. If the Comm LED does not flash when thermostat first calls for equipment, turn that zone DIP switch to Off. Refer to Setup section to reset the W8665. If the Zone LED flashes continuously, turn that zone DIP switch to Off.Refer to Setup section to reset the W8665.
Check if 24 Vac is present:
Check between R and C on W8665.
Check between Y of troubled zone and C on W8665. If voltage is present, troubleshoot cooling system. Wait is displayed and the call for cool has not started. Compressor protection is in effect. 2nd stage heat or cool (or 3rd stage heat) does not energize. W8665 is not wired to a TZ-3 TotalZone Zone Control Panel that controls the multiple heat and cool stages. Compressor protection can be set on the T8665A from 0 to 5 minutes to prevent compressor damage due to rapid cycling. Wait until the compressor protection period expires. Wire W8665 to TZ-3 TotalZone Zone Control Panel to control multi-stage systems. Check TZ-3 TotalZone Zone Control Panel and set correctly. Fan does not come on with a call for electric heat. Electric heat setting is not configured. Set thermostat Installer Setup Number 2 to 1 for electric heat. See thermostat instructions for details. Fan load at W8665 is not connected correctly. Check that 24 Vac is present between R and C. Check that 24 Vac is present between G and C. If voltage is present, troubleshoot system. 7 69-1534-1
