Full DC inverter mini Heat pump adopts highly intelligent inverter-driven compressor. This advanced technology
enables the output of the outdoor unit to be modulated by the real heat load demands..
This advanced system ensures precise temperature regulation and highly efcient energy usage, making a
signicant contribution to limiting the impact on the environment.
Optimally design fan shape and new designed discharge air grille and air deector, making higher air volume and
lower operation sound.
Stable and safe running in wide ambient temperature range, cooling performance from 10 ˚C to 46˚C, heating from
-20˚C to 35˚C.
By adopting high efciency Coaxial heat exchanger or tubes in shell heater exchanger, the energy consumption can
be reduced.
Compact devices with advanced function and friendly user interface.
The Heat pump can be controlled by optional wired controller (YR-E27) ,
Fully integrated and built-in hydraulic module, such as Coaxial heat exchanger or tubes in shell heater exchanger,
water circulating pump, the water pressure difference switch, etc. It saves installation space and cost.
Stable and accurate gas ow control. EXV achieves 500 pulses to adjust ow precisely. Ensure the temperature-
control precisely and steadily to provide a comfortable environment.
Fast respond resulting in higher efciency and improved reliability.
Press the key “Set” of YR-E27 for 15 seconds to start the water pump operating when the unit is standby. Press “Set”
key for 15 seconds again to stop the water pump.
Built-in with voltage protection, current protection, anti-freezing protection, water ow protection and etc., effectively
guarantee the system to work safely.
Hydrophilic lm ns and inner-threaded copper pipes optimize heat exchange efciency.
