Troubleshooting

Problem Possible cause Solution

After powering up or a factory
reset, INSTEON Wireless
Thermostat displays a two-digit
error code instead of the ambient
temperature.

I replaced my INSTEON Wireless
Thermostat with a new one, but
now the INSTEON for Hub app
doesn’t recognize it.

ETSI EN 300 220-1 & 220-2, ETSI EN 301 489-1 & 489-3 (Eu)
AS/NZ 4268 (C-Tick N16509)

C-Tick N16509 (Aus/NZ model)

It didn’t boot up fully. Remove batteries from INSTEON

Wireless Thermostat, wait a few
seconds, then reinstall. If
problem persists, call the
INSTEON Support Line.

The INSTEON for Hub app
communicates via INSTEON
I.D.s. They are still trying to
communicate to the old
thermostat’s I.D.

Update the INSTEON I.D. on
both the Hub and the INSTEON
for Hub app with your new
thermostat’s I.D.

My INSTEON Wireless
Thermostat temperature reading
is taking a long time to update on
my INSTEON Thermostat
display.

INSTEON Wireless Thermostat’s
battery life seems very short.

At the top of each hour and, :15,
:30, and :45 past, the INSTEON
Wireless Thermostat will wake up
and synchronize the readings
with the INSTEON Thermostat
display.

Battery life depends on individual
settings (such as LED backlight

Use an AC adapter (sold

modules between the two

separately) to power INSTEON
Wireless Thermostat.

The displayed temperature and
humidity don’t seem accurate.
When the Wireless thermostat is
placed near the Wired
Thermostat, the temperature and
humidity readings are different.

When the power is removed, the
clock settings are lost

When you change the Master
mode from the INSTEON
Wireless Thermostat to the
INSTEON Thermostat, the
Wireless Thermostat still reads
master.

When the Wireless Thermostat is
linked to a Wired Thermostat, it
will not directly control other
linked devices based on
temperature or humidity

Both units were calibrated at the
factory prior to shipment. Other
factors could contribute to
different readings.

Use the Calibration feature to
adjust either the temperature and
humidity so the two unit match
and the temperature feels about
right.

The Wireless Thermostat does
not have a back-up clock that
keeps the time

If linked to an INSTEON Wired
Thermostat, the Wireless
Thermostat will pull the current
time, temperature, and settings
every 15 minutes.

The Wireless Thermostat will
wake up and synchronize data
with the Wired Thermostat:

During the synchronization, the
“Master” icon will clear on the
Wireless Thermostat.

• Every 15 minutes.

• If it detects a temperature

change.

• If the up/down temperature
buttons are pressed.

This is normal. Have your Wired Thermostat be

the controller of other devices
based on temperature and
humidity.

When an AC adapter is used, the
temperature and humidity
settings are changing rapidly.

When I move the Wireless
Thermostat to a cold room, the
temperature does not update

The Wireless Thermostat will not
go into Master Mode.

The Wireless Thermostat or
Wired Thermostat goes out of

Noise from the AC adapter is
affecting the Wireless
Thermostat’s electronics.

The unit will update the display
every minute. Also, the case and
electronics of the unit will hold
the warmth of the previous room
for up to an hour.

The air flow into the Wireless
Thermostat may be blocked

The Wired Thermostat only
allows up to two Wireless
Thermostats and will reject three
or more.

The two units are too far from
each other and unable to

Be sure that your AC adapter is
outputting between 5 to 7.5 volts.

Change to a better quality AC
adapter.

After about one hour, the
temperature display will stabilize
and show an accurate figure.

Be sure to use the included stand
or mount the unit on a wall to get
good air flow.

Unlink the Wireless
Thermostat(s) or reset all units
and re-link.

each will go out of the Mater
mode after 30 to 60 minutes

The temperature setpoints and
the Mode changes from what it
was set to.

Computer software or other
controller can’t retrieve the
Wireless Thermostat’s data
(Temperature, Humidity,
Setpoints).

The Wireless Thermostat seems
slow to update the sensed
temperature and humidity.

The Wired Thermostat is the
Master (or perhaps a different
Wireless Thermostat) so the
setpoint levels and mode
changes (Heat, Cool, etc.) made
at the Wired Thermostat
(manually, following the Auto­schedule, or via another
INSTEON controller) are being
sent to the Wireless for display.

When using only batt eries , the
Wireless Thermostat will go to
sleep and not responded to
signals from other INSTEON
devices.

The unit wakes up every minute
and checks for changes. If
differences are detected, the
display is updated and
communicated to linked devices.

Press the Master button on the
Wireless Thermostat so that it
becomes the master and its
mode and setpoints are
controlling the Wired Thermostat.

Add an AC adapter and the unit
will stay on and awake all the
time.

Use an AC adapter for
continuous temperature and
humidity monitoring.
