New Generation Can Bus Communication; Long Connection Pipe; Wide Operation Range; Fine Sound Quality - Gree GMV-24WL/C-T Service Manual

GREE
GMV-60WL/A-T(U) is up to 8.2.
For the upgraded efficiency DC Inverter Multi VRF System, SEER is up to 19.5~22; HSPF of
GMV-36WL/C-T(U) and GMV-60WL/C-T(U) is up to 10.5~11; HSPF of GMV-48WL/C-T(U) is up to
10.6~10.8.

(2) New generation CAN bus communication

Due to the latest communication method—CAN Bus Communication, system's anti-interference
capability is stronger and the control on indoor units is more accurate, with higher reliability. Specialized
shield wire is no more needed and ordinary communication wire can be applied in the construction,
which has increased the installation flexibility.

(3) Long connection pipe

The maximum length of connection pipe is 300m（984ft） (in total) and the farthest connection pipe
between indoor and outdoor units can be 120（394ft）m's long, which has extended the installation
condition and reduced the limit of installation distance.

(4) Wide operation range

Units can operate reliably in a wide temperature range (cooling: -5~48℃(23~118℉) ), heating:
-20~27℃(-4~81℉)

(5) Fine sound quality

Through a series of optimized measures, system has reduced the throttle noise and oil return noise
of indoor units, gas bypass noise, etc. so that units are more comfortable regarding sound quality.
(6) Intelligent PID capacity regulation
With the independently developed PID capacity regulation technology, units are able to control the
indoor ambient temperature more quickly and reduce the fluctuation of room temperature.
(7) Complete protection
Units are equipped with a series of protection to accurately identify errors and protect the units,
which has ensured reliable and safe operation.
