Wiring the Smart Controller Power Cord and 24V Transformer
CAUTION! DO NOT PLUG THE TRANSFORMER INTO THE WALL UNTIL ALL WIRING IS
COMPLETED.
The Smart Controller is powered by a 24 VAC and 2.1 Amps (50 VA) transformer (P/N 01014897, 60 Hz). If there are
multiple controls in the system being installed, each controller will require its own transformer. It is recommended that
each transformer be plugged into a dedicated 120V circuit.
CAUTION! Connecting 24 V to the 2.5 V connection on the circuit board will damage the circuit
board.
NOTE The 2.5 V cord is only necessary when using an Aqua-Sensor.
CAUTION! To eliminate the possibility of polarity issues, carefully follow the wiring details shown
in Figure 22.
