Programming For An External Controller - Aquacal Heatwave Superquiet TropiCal Installation Manual

Two-wire controller (with internal thermostat):
1. Deactivate power to heat pump.
2. Remove heat pump electrical access panel.
3. Route the control wiring to the low voltage side of the electrical enclosure. Follow all National Electric Codes
(NEC) unless State or Local guidelines supersede.
4. Connect the controller wires to the microprocessor as follows:
Connect one wire to "Y".
l
Connect other wire to "Z".
l
The polarity of the wire is not important.
l
5. Reattach heat pump access panel.
6. Apply power to heat pump.
7. Program heat pump for a two-wire controller. See "Using JAO interface" on page 20.
Three-wire controller (with "OFF" position):
1. Deactivate power to heat pump.
2. Remove heat pump electrical access panel.
3. Route the control wiring to the low voltage side of the electrical enclosure. Follow all National Electric Codes
(NEC) unless State or Local guidelines supersede.
4. Connect the controller wires to the microprocessor as follows:
Connect "Low" or "Pool" wire to "X".
l
Connect "High" or "Spa" wire to "Z".
l
Connect "Common" wire to "Y".
l
5. Reattach heat pump access panel.
6. Apply power to heat pump.
7. Program heat pump for a three-wire controller. See "Using JAO interface" on page 20.
Three-wire controller (without an "OFF" position):
1. Deactivate power to heat pump.
2. Remove heat pump electrical access panel.
3. Route the control wiring to the low voltage side of the electrical enclosure. Follow all National Electric Codes
(NEC) unless State or Local guidelines supersede.
4. Connect the controller wires to the microprocessor as follows:
Connect "Common" wire to one terminal of "FS2".
l
Connect "Spa" to other terminal of "FS2".
l
The third wire is not used.
l
5. Reattach heat pump access panel.
6. Apply power to heat pump.
7. Program heat pump for an external controller. See "Using FS2 interface" on page 20.
