Air conditioner installation
1.
At the thermostat, turn mode to OFF.
2.
Turn off power to the AC unit (either at the outdoor unit or at the main breaker panel).
NOTE:
If AC is running at the time of installation, it is recommended to first shut down the unit
from the thermostat before turning off at the outdoor shutoff or main breaker to avoid system
resets after power is restored.
3.
Open the cover on the outdoor AC unit where the electrical connection and thermostat wire
are housed.
4.
Locate the two incoming wires going to the contactor (L1) and (L2). Clamp both 50A
CTs around either (L1) or (L2) as space permits. CTs may be placed on the same wire or
separately Ensure both CTs are firmly clamped around the wire and the latch is snapped shut.
5.
Route 3.5 mm jack out of the cabinet through the grommet that the thermostat wire (low
voltage) is coming through, typically the bottom of the cabinet.
NOTE:
If the existing grommet can't accommodate the additional wires, drill another hole and
add a grommet (not included) to protect the wires, or find another way to route the wires out of
the enclosure.
6.
Pull excess wire through the hole and ensure the CTs and wires are not near any other
terminal blocks, etc. Use zip ties and/or tape to route wires as necessary (not provided).
7.
Plug the CT 3.5 mm jacks into the labeled ports: C to C (powering CT) and 1 to 1 (sensing
CT). Push the 3.5 mm jack firmly into the
ports.
8.
Assess the locations on the adjacent structure
that the CT cables will reach.
9.
Drill pilot holes and add anchors (if necessary)
to mount the enclosure to the home exterior.
10.
Close the cover of the enclosure with the
screw provided. Orientation with wire exiting
the bottom of the enclosure is required.
11.
Coil and/or wrap excess wire with zip ties and
attach it to the conduit that the thermostat
wire is typically routed through.
12.
Double check that the CT clamps are closed and all wires are
routed properly.
13.
Put the cover back on the wiring connections at the AC unit.
14.
Turn power back on to the AC unit.
NOTE:
The Sensor Hub LED will remain off until the AC unit is
running and provides enough current to start up the Sensor Hub. In
the off-season, unit will go into deep sleep mode. See LED and UI
button tables in following pages for additional information.
