* Smart microchip control and large LCD user interface, capable of one-key startup. 

* Automatic intelligent reset. Unit shall automatically restart 5 minutes after shutdown if the fault has cleared. Should a fault occur 3 times sequentially, then lockout will occur.

* Humanized design, widened application scope: the unit's temperature settings for room, hot water, water intake/outlet, freeze protection, and compressor exhaust can be adjusted on-site according to environmental conditions. 

* Communication adapter connection the unit to BMS(Building Management System) is an optional accessory, please get in touch with us or our distributor if required. 

* Unit with multi-protection to guarantee the unit running stability and security, such as: high/low voltage, low oil level protection, exhaust temperature, antifreeze, power lack/reverse phase,water system cut off. operating condition with small change range stable operation, safe, reliable and long service life.

* Easy installation,  simple water piping system configuration, you can make design partition and divide second installation.
