Procedure

  1. Terminate the ZEC wiring according to Figure 3. Terminate the BYP wiring according to Figure 1.
  2. Wire the zone sensor to the ZEC’s Sensor Bus.
  3. Wire the Zone Bus in a daisy chain.
  4. Ensure that the controller’s device address DIP switches are set to the appropriate device address. (See Setup and adjustments). Also, activate the end-of-line (EOL) switch if necessary.
    Important: Maintain proper polarity and voltage or current ratings. Improper polarity or exceeding the voltage or current ratings voids the warranty.
  5. Connect the controller to 24 VAC, Class 2 power.
