Connecting a Source Water Relay Switch

A direct connection to a source water relay switch has been provided on the terminal microprocessor.

A source water switch will automatically activate or deactivate a geothermal source pump.

DANGER

Failure to heed the following will result in injury or death.

 

  • Deactivate power while routing wiring to control board.
  • Follow all National Electric Codes (NEC) and/or State and Local guidelines.

WARNING

Failure to heed the following may result in injury or death.

 

  • This section is only for qualified installers who are familiar with the swimming pool and spa safety standards.
  • The installer must be familiar with service industry techniques.

NOTICE

Failure to heed the following may result in damage to equipment.

 

  • The wire size connecting the relay switch must be a minimum 22-gauge, 2-conductor, low-voltage wire.
  • Use Fan (dry contact) connection on the microprocessor.

Dry Contact Connection Points to the Microprocessor

  1. Deactivate power to heat pump.
  2. Remove heat pump electrical access panel.
  3. Route wires from the relay switch to the low voltage side of the electrical enclosure. Follow all National Electric Codes (NEC) unless State or Local guidelines supersede.
  4. Connect the wires to the "Fan" jumper as indicated. Polarity is not important. Please note - While this connection point is labeled "Fan", it can be used as an optional connection point for controlling a geothermal relay switch.
  5. Reattach heat pump access panel.
  6. Apply power to heat pump.
