Outdoor inverter units are approved for operation above
0°F in cooling mode and -20°F (RH10%) in heating mode

FEATURES
This heat pump is part of a ComfortBridge™ control system
that uses inverter technology to more eciently control
heat gain/loss with better eciency and achieve targeted
comfort conditions.
The system utilizes digital communication between the
indoor and outdoor equipment and can be controlled by
any single-stage thermostat.
The ComfortBridge control system reduces the number
of required thermostat wires, provides additional setup
features and enhanced diagnostics through Bluetooth
connectivity with the CoolCloud™ app.
Due to components using inverter technology, the heat
pump will not function properly if used with a non-approved
control system.
