Glossary
C wire
The "C" or common wire brings 24 VAC power to the thermostat from the heating/cooling
system. Some mechanical or battery operated thermostats may not have this wire connection.
It is necessary for establishing a Wi-Fi connection to your home network.
Heat Pump heating/cooling system
Heat pumps are used to heat and cool a home. If your old thermostat has a setting for
emergency heat, you likely have a heat pump.
Conventional heating/cooling system
Non–heat pump type systems; these include air handlers, furnaces or boilers that run on
natural gas, oil or electricity. They may or may not include an air conditioner.
Jumper Loop
In this thermostat, a plug with a wire loop located below the terminal block is used to connect
the R and Rc terminals.

Regulatory information
FCC Compliance Statement (Part 15.19) (USA only)
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1 This device may not cause harmful interference, and
2 This device must accept any interference received,
including interference that may cause undesired
operation.
FCC Warning (Part 15.21) (USA only)
Changes or modifications not expressly approved by the
party responsible for compliance could void the user's
authority to operate the equipment.
FCC Interference Statement (Part 15.105 (b)) (USA only)
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates uses
and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.
Thermostats
To comply with FCC and Industry Canada RF exposure
limits for general population/ uncontrolled exposure, the
antenna(s) used for these transmitters must be installed
to provide a separation distance of at least 20 cm from
all persons and must not be co-located or operating in
conjunction with any other antenna.
RSS-GEN
Under Industry Canada regulations, this radio transmitter
may only operate using an antenna of type and maximum
(or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other
users, the antenna type and its gain should be so chosen
that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that necessary for successful communication.
Operation is subject to the following two conditions:
1 This device may not cause interference, and
2 This device must accept any interference, including
interference that may cause undesired operation of the
device.
