The control can be mounted
on a standard DIN rail. First
remove the control from its
base and then, using the hooks
and spring clip on the back of
the control, mount it onto the
DIN rail. This will be a popular
option for those who prefer to
mount the control inside a larger
electrical panel.
The wiring can enter the
bottom or the back of the
enclosure. Knock-outs pro-
vided in the base allow the
wiring to be run in conduit
up to the enclosure. The
base also has holes that
line up with the mounting
holes of most common
electrical boxes.
Press down at the fi ngertip grips
on top of the front cover and pull
out and down.
Lift the front cover up and away
from the control.
Loosen the screws at the front
of the wiring cover.
The wiring cover pulls straight out
from the wiring chamber.
The base is ready for mounting.
The control lifts up and away
from the base.
Press the control release clip
on the base inside the wiring
chamber and slide the control
upwards.
Remove the safety dividers
from the wiring chamber by
pulling them straight out of their
grooves.
There are 10 conduit knock-outs at the back
and bottom of the wiring chamber.

ROUGH-IN WIRING
All electrical wiring terminates in the control base wiring chamber. The base has standard 7/8” (22 mm) knockouts, which accept
common wiring hardware and conduit fittings. Before removing the knockouts, check the wiring diagram and select those sections
of the chamber with common voltages. Do not allow the wiring to cross between sections, as the wires will interfere with safety
dividers which should be installed at a later time.
Power must not be applied to any of the wires during the rough-in wiring stage.
••
All wires are to be stripped to a length of 3/8” (9 mm) to ensure proper connection to the control.
••
Install the Outdoor Sensor 00228 according to the installation instructions in this brochure and run the wiring back to the control.
••
Install the Boiler Sensor 00229 according to the installation instructions in this brochure and run the wiring back to the control.
••
Run wire from other system components (pumps, boilers, etc.) to the control.
••
Run wires from the 115 V (ac) power to the control. Use a clean power source with a 15 A circuit to ensure proper operation.
Multi-strand 16 AWG wire is recommended for all 115 V (ac) wiring due to its superior flexibility and ease of installation into
the terminals.
