Separate line and low voltage circuits.
Do not run line voltage wiring through bottom
section of enclosure that houses the control board.
Do not run low voltage wiring through top section
of enclosure that houses the relay board.
Do not run line and low voltage wiring
in the same conduit.
NOTE 1: This diagram applies to the Satellite Controller only.
The Satellite Controller does not require modem, RS-485 converter wiring to the PC, TCP/IP module wiring, or outdoor sensor wiring.
For Central Controller see Central Controller External Wiring Diagram.
NOTE 2: Twist shield wires for both RS-485 communication cables together. On controller #1 only, connect these twisted shield wires
to ground. For VFD 0-10 V signal wiring, connect shield wire to ground at the controller only.
NOTE 3: 120 V 1 Ø 50-60 Hz supply for 120 V VFD model. 230V 1 Ø 50-60 Hz supply for 230 V VFD model. See VFD rating plate
for required input. Repetitive cycling of a disconnect or input contactor (more than once every two minutes) may cause
damage to the drive.
NOTE 4: Zone 3 Sensor(not shown) wiring is as follows: SEN output to analog input 3; SET output to analog input 6;
O/R output to meter input 3; +/- outputs to +16 V/GND inputs.
NOTE 5: Internal pre-wiring not shown.
NOTE 6: All three power output wires from terminals U, V, and W to the pump motor must be kept tightly bundled and run
in a separate conduit away
from all other power and control wiring.
