GMV5 HR HEAT RECOVERY
VRF Units Technical Sales Guide
Ambient temperature:-10ºC(14ºF)~20ºC(68ºF) for Heat recovery .
1.9 Module switching control
The module status automatically switches between modules every eight hours according to the operating
status. This avoids long-term “waiting for work” of several modules and greatly improves reliability of
the whole system.
1.10 High static pressure design of the outdoor unit to realize more flexible selection
The unit is provided with four levels of static pressures
：
0 Pa(0In.W.G), 30 Pa(0.12In.W.G), 50
Pa(0.20In.W.G), and 82 Pa(0.328In.W.G). The corresponding static pressure can be selected for the
outdoor unit according to the building form, and the maximum static pressure is 82 Pa(0.328In.W.G).
The unit especially applies to the scenario where the outdoor unit needs to be placed indoors.
