1. Ensure Unit power has been disconnected and
locked out.
2. Disconnect both fan motor harnesses from
contactors, install 14 gauge wire harnesses
(supplied in kit) between the controller, fan
contactors and outdoor fan motor harnesses for
both refrigeration circuits. See
Figure 9, p. 11 .
3. FOR HEAT PUMP UNITS ONLY, connect Switchover
valve 1 (SOV1) harness (supplied in kit) using the
following steps:
a. Disconnect black wire from SOV1. See Figure
10, p. 12 .
b. Reconnect black wire to black wire in kit harness
by making an in-line connection. Securely
attach this in-line connection to adjacent wiring
with wire ties. See
Figure 11, p. 12 .
c. Connect terminal with black and orange wires to
the open tab on SOV1. See Figure 11, p. 12 .
d. Connect orange wire with stripped end to Rev
valve terminal on low amb controller 1. See
Figure 11, p. 12 .
4. FOR HEAT PUMP UNITS ONLY, connect Switchover
valve 2 (SOV2) harness (supplied in kit) using the
following steps:
a. Disconnect blue wire from SOV2. See Figure
10, p. 12 .
b. Reconnect blue wire to black wire in kit harness
by making an in-line connection. Securely
attach this in-line connection to adjacent wiring
with wire ties. See
Figure 11, p. 12 .
c. Connect terminal with black and orange wires to
the open tab on SOV2. See Figure 11, p. 12 .
d. Connect orange wire with strip end to Rev valve
terminal on low amb controller 2. See Figure
11, p. 12 .
5. Install jumper harness (supplied in kit) between the
two controllers. See diagram for reference. See
Figure 12, p. 13 .
6. Install 24VAC harness (supplied in kit) between unit
controller (UC-P5) and the Low Ambient
Controller1. See
Figure 13, p. 13 .
7. For each refrigeration circuit install transducer
wires to controller as per kit diagram. See Figure
14, p. 14 .
8. For each refrigeration circuit install the thermistors
on the outdoor air sensor bracket and connect on
controller as per kit diagram. See
Figure 15, p. 15 .
9. Finish wiring installation.
a. Using wire ties, bundle and dress any excess
wires away from sharp edges, moving parts, or
hot tubes.
b. Apply the diagram (supplied in kit) to an open
area on the low voltage access panel. See
Figure 2, p. 7 for proper replacement.
c. After the settings have been properly adjusted
(see “ “Controller Settings,” p. 15 ), reinstall the
compressor and control box access panels and
secure with screws that were removed.
