24VAC POWER-IN FOR PC
BOARD — The circuit board
for the Pump/Valve Switch
requires 24VAC power
from the transformer.
OMRON CONNECTIONS
— Each of the two Omron
relays connects to the PC
board at these points.
SENSOR LINE PLUG IN — The pool to spa mechanism
supports up to two auxiliary 3HP circuit loads. You
can have different source voltages for each circuit,
depending on your equipment requirements. The sensor line
allows the mechanism to be controlled by a single-pole
single throw switch. (i.e., a toggle switch, relay, wall switch, etc.)
POOL/SPA SWITCH CONNECTION — located on the face of the Pump/
Valve Switch mechanism connects to the PC board at this point, and
allows you to switch between the pool and spa thermostat or just the
spa only. In the spa only mode, the pool thermostat is disabled.
EXTERNAL TIMER PLUG IN —
into the PC board at this point
to control relay #1. Please see
page xx for instructions on
using an external timer.
OMRON RELAY #2 — This
relay can switch either
120V or 240V loads.
Can be ordered separately
(145T145A)
CONTROL FACE PLUG IN — a
control pad for service. The
control pad connects to the
PC board at this point.
OMRON RELAY #1 — This
relay can switch either
120V or 240V loads. Can
be ordered separately (145T145A)
