6. At the Power Center, route the cable up through the 1” grommet and low voltage raceway to the
circuit board. See illustration on page 4 and 8.

PL4/PSL4 Control Systems Circuit Board:
Connect the Valve A actuator cable
plug into the
INTAKE
(suction) 3-pin socket, and Valve B actuator cable plug into the
RETURN
three-pin socket on the right side of the EasyTouch PL4/PSL4 Control Systems circuit board.
Excess cable can be coiled in the enclosure low voltage raceway left side compartment (see
page 3). Do not coil the conductor in upper low voltage compartment. For valve actuator circuit
board socket location as shown below. For plumbing requirements, see Item 2 and 3 on page
36.
Installing and Connecting Temperature Sensors
Water Temperature Sensor
To install the water sensor:
1. Select a convenient location to mount the water sensor in the plumbing system between
the filter pump and filter. Drill a 3/8” diameter hole in one side of the pipe,
2. Insert tip of sensor into the hole. Use the band clamp to secure the sensor to the pipe.
Tighten the clamp just enough so that the o-ring begins to flatten. Do not overtighten
3. Fasten the cable to the plumbing with cable ties.
4. Run 22 AWG two-conductor cable (included in kit) between the sensor and the
enclosure. Route the cable up through the low voltage raceway to the circuit board.
5. Cut off the excess conductor and the strip conductors ¼ inch. Use waterproof
connectors (provided) to connect the sensor to cable.
6. Insert the conductors into the
WATER SENSOR
screw terminals (
J21
) on right-side of
the motherboard. For sensor circuit board screw terminal location see illustration on next
page and page 31).
Ambient Air Temperature Sensor (for freeze protection)
To install the air sensor:
1. Mount the sensor in the open air, in a shaded area, away from air conditioners. During the
winter months, to avoid freeze damage to pool and spa equipment, mount the air sensor in
a shaded area to assure proper temperature readings. The main screen displays the current
ambient air temperature.
2. Fasten the cable to the plumbing with cable ties.
