When cooling ,the outlet water temperature of indoor exchanger is lower than 〖C2〗
set value, sustained 10 seconds in 〖bE〗 times / h, the compressor will be protected, if the
the water temperature rise to the set value ,the compressor 〖C9〗 minutes delayed restart.
In more than 〖bE〗 times , the controller is locked, the compressor will not restart with the
water temperature regardless of whether or not to resume. water temperature <8 ° is the
special models, no anti-freeze protection
16)． Outlet water temperature is too high to protect in heating.
When heating, outlet water temperature is higher than 〖C3〗(sets),and last 10 seconds
in an hour less than 〖bE〗 times ,the compressor is protected，when outlet water
temperature is restored , compressor will restart (meet 〖C9〗 minutes delay). In more than
(〖bE〗 times per hour) of fault the controller is locked, the compressor is no longer restart
regardless of whether outlet water temperature reset, and display the fault code.
17)． difference in temperature protection when Water shortage.
When the unit run for refrigeration or heating in a moment，if difference in outwater
temperature and backwater temperature is greater than sets(Air-conditioning water
temperature〖C5〗; Water source temperature is〖C6〗)，and last 10 seconds in an hour less
than 〖bE〗 times , the controller can difference in temperature protection，and display the
fault code.
18)． Winter antifreeze protection.
In order to prevent freezing indoor air-conditioning water in winter, the controller
based on the parameter of〖C7〗
〖C8〗for antifreeze protection in winter.the Controller set up
two anti-freeze protection,Firstly , circulate pump and electrical heating running〖C7〗；
