12. back-upfunction
In the event of a compressor malfunction, the remotely controlled or field set back-up function in the outdoor unit in question (and also between different outdoor units) will allow emergency operation of another compressor in order to maintain 8 hour maximum interim capacity.
13. continuous heating during defrost
Heating cycle is continued also while defrost operation, (without hot start)
The defrost period of VRV®III is shorter and the peak performance is higher compared to VRV®II. Continuous heating during defrost results in a higher integrated heating capacity and much higher comfort levels for the users.

14. year round cooling and/or heating
Designed to provide simultaneous year round cooling and/or heating, VRV® heat recovery systems are modular in concept and are therefore, ideal for use in rooms or zones that generate varying thermal loads according to building orientation or local hot or cold spots.
It is possible for the same meeting room to give rise to differing thermal loads depending on the time of day, number of occupants present, location and usage pattern of lighting and electronic office equipment.
The colder it is outside, the warmer it needs to be indoors, which means that the capacity of the air-cooled outdoor unit drops. Water-cooled air conditioners are not subject to this problem. The boiler ensures that sufficient enough additional heat is always available indoors.
