Troubleshooting
Heating or cooling doesn’t turn on when
the set point is above or below the
room temperature
To prevent damaging the compressor,
the thermostat inserts a delay when cycling
the compressor. If you think the system should
be on and it’s not, change the set point to
2 degrees beyond the current set point and wait
5 minutes to see if the system turns on.
If not, contact a local HVAC professional.
Heat pump is “cooling when it should
be heating” or “heating when it
should be cooling”
Because both types of heat pump reversing
valves share a single terminal on your
thermostat back plate, you need to be sure
you have the thermostat configured for
the correct wire. Try switching the O/B
configuration setting through your
online account. Contact a local HVAC
professional for further help with this issue.
Exclude the thermostat from the
Z-Wave network
If for some reason the thermostat must be
excluded from the network, follow the
steps below:
❶ Set the thermostat to OFF mode.
❷ Press and hold the exclusion button on the
Z-Wave controller. Refer to controller
documentation for more information.
❸ Press and hold the DOWN button on
the thermostat to enter exclusion mode.
Release the button when the RADIO
icon lights up.
❹ When the RADIO icon flashes red,
the thermostat has now been successfully
excluded from the network.
Batteries drain quickly
If a thermostat is included using a “C” Wire,
that information is saved in the network and
cannot be changed unless excluded and included
again without a “C” Wire connected. The same
applies to thermostats included on
battery power.
If you find your thermostat batteries are
draining unusually fast, make sure the “C” Wire
connection is still intact. If a device is included
using the “C” Wire, the Z-Wave communication
never sleeps, and the thermostat will act as a
repeater, sending messages for other devices
as well. If the “C” Wire is removed, this kind of
activity will drain the battery very quickly.
