  • What's Included
  • Have you ever needed another wire or two when installing a thermostat or other component of your HVAC system? Now you don't have to pull a new cable! Use these transceivers instead. The base module can transmit 3 channels, and the satellite module can send one channel. The pair can effectively take the place of 4 conductors of HVAC cable. They operate on 24VAC from your system or a 24VAC power supply. Maximum range of up to 200' and there are 6 programmable house address codes. The command protocal requires feedback, so the failsafe feature turns all outputs off if no acknowledgement signal is received within 60 seconds.
