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 disconnect
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).
Pull a three conductor 14 AWG cable for the following
equipment:
Circuit Breaker or Power Disconnect

Boiler System Pump
DHW Tank Pump (if applicable)
