Connecting A Source Water Relay Switch; Connecting External Controllers To Heat Pump - Aquacal WATER SOURCE WS03 Installation Manual

1.6.b 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
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.
l
WARNING
This section is only for qualified installers who are familiar with the swimming pool and spa safety standards.
l
The installer must be familiar with service industry techniques.
l
NOTICE
The wire size connecting the relay switch must be a minimum 22-gauge, 2-conductor, low-voltage wire.
l
Use Fan ( dry contact) connection on the microprocessor.
l
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.
