Electrical Installation
Installing Valve Actuators
For shared equipment systems there are two motorized valve actuators (CVA-24T, P/N 263045).
To install the valve actuators:
1. Remove the valve knob, handle and the four screws, from the valve cover (indicated with ar-
rows).
2. Align the splines of the actuator shaft over the shaft of the valve.
3. If the actuator is not aligned with the mounting holes on the valve cover, rotate the actuator
(while still attached to the valve) until the actuator is positioned correctly over the valve.
4. Secure the actuator with the screws provided. Only use self-tapping screws when required.
5. Mount the valve handle and knob onto the actuator.
6. At the Load Centre, route the cable up through the 1" grommet and low voltage raceway to
Personality board.
7. 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 motherboard (for
more information, see Item 2 and 3 of Plumbing requirements on page 3). For motherboard
connection details, refer to "EasyTouch Motherboard Connections," on page 13. For wiring
details, refer to "EasyTouch System Wiring Diagram," on page 23. Excess cable can be coiled
in the enclosure low voltage raceway left side compartment. Do not coil the wire in upper low
voltage compartment.
For Solar Heating use VLV A (3-pin socket). Use VLV B (3-pin socket) for an optional auxiliary relay.
Adjusting the valve position
If the valve rotates to the wrong position, adjust the switch on the back of the actuator between
ON1 and ON2 positions. This will rotate the valve to the correct position. The following diagram
shows the standard plumbing and valve actuator position.
