Power Required
----------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------
115 V (ac), 1-phase, 15 A service from circuit breaker panel
(potentially up to two circuits)
•
Power disconnect (optional)
•
Installation Location
When choosing the location for the control, consider the
following:
Keep dry. Avoid potential leakage onto the control.
RH 90% to 104°F (40°C).
Non-condensing environment.
Do not expose to operating temperatures beyond 32-104°F
(0-40°C)
Provide adequate ventilation.
Keep away from equipment, appliances or other sources of
electrical interference.
Locate the control near pumps and/or zone valves if possible.
•
•
•
•
•
•
Provide easy access for wiring, viewing and adjusting the
control.
Mount approximately 5 ft. (1.5 m) off the finished floor.
Install the electrical junction box to a wall using #10 x
1” wood screws. Wall anchors are recommended when
mounting to sheet rock wallboard or masonry.
Install the extension ring onto the electrical junction box.
Total box volume must be 38 cubic inches (623 cm
3
) or
greater to comply with National Electrical Code (NEC) or
Canadian Electrical Code (CEC).

Rough-In Wiring
Line Voltage Wiring
------------------------------------------------------------------------------------
------------------------------------------------------------------------------------
The control operates a number of pumps through wiring on
the back of the control. The control must be mounted to a 4” x
4” electrical junction box so that these electrical connections
are safely contained.
For ease of service, the circuit breaker or power discon-
nect should be located in reasonably close proximity to the
equipment.
All line voltage wire connections are recommended to be pulled
inside a flexible or solid conduit. Always follow proper wiring
practices, building and electrical codes for your jurisdiction.
Each cable must be pulled from the equipment to the electrical
junction box. It is recommended to label each cable for easy
identification. All line voltage wires should be stripped to a
length of 1/2” (13 mm).

Low Voltage Wiring
-------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------
Each cable must be pulled from the equipment to the control’s
plastic enclosure. All low voltage wiring connections enter the
enclosure through conduit knockouts on the sides, or through
the square knockouts on the rear. It is recommended to label
each cable for easy identification. All low voltage wires are
to be stripped to a length of 3/8” (9 mm) to ensure proper
connection to the control.
