Step 5 — Wire Low Voltage Connections
WATER FREEZE PROTECTION — The Aquazone™ con- trol allows the field selection of source fluid freeze protection points through jumpers. The factory setting of jumper JW3 (FP1) is set for water at 30 F. In earth loop applications, jumper JW3 should be clipped to change the setting to 10 F when using antifreeze in colder earth loop applications. See Fig. 30.

ACCESSORY CONNECTIONS — Terminal labeled A on the control is provided to control accessory devices such as water valves, electronic air cleaners, humidifiers, etc. This signal operates with the compressor terminal. See Fig. 31. Refer to the specific unit wiring schematic for details.
NOTE: The A terminal should only be used with

WATER SOLENOID VALVES — An external solenoid valve(s) should be used on ground water installations to shut off flow to the unit when the compressor is not operating. A slow closing valve may be required to help reduce water hammer. Figure 31 shows typical wiring for a
1.The valve will remain open during a unit lockout.
2.The valve will draw approximately 25 to 35 VA through the “Y” signal of the thermostat.
IMPORTANT: Connecting a water solenoid valve can overheat the anticipators of electromechanical thermo- stats. Only use relay based electronic thermostats.
