9). Cooling set temp can’t lower than 〖bb〗value
10)． 〖P2〗 heating set temperature must not exceed the upper limit of the value〖bC〗
11)． Temperature compensation for water temp. sensor.
In some special applications, if the wire of sensor is too long or sensor installation
location restrictions, need to correct the temperature value measured by sensor. This
function can be by adjusting the parameters of 〖bd〗, when in antifreeze model without
compensation.
12)．
For high and low pressure, difference in temperature of inlet water and outlet water,
coil temperature overheating and so on, which are protected on the number of settings.
when it occur the protection of
〖bE〗times in an hour.
then the controller of the fault is
locked, or else it may resume.
13). set the protected number for high and low pressure, the water temp. of outlet(indoor
and outdoor), the water temp. difference of outlet and inlet,when the protected number
access to set value〖bE〗 within 1 hour, the fault is locked, or restore
14). The protection due to too high coil temp. In cooling model.
When cooling ,the coil temperature is higher than set value 〖C1〗, and sustained 10
seconds (in〖bE〗 times / h), the compressor will be protected. When the coil temperature is
restored , the compressor restart after the delay time〖C9 〗minutes. If the protected number
more than〖bE〗 times / h, then the controller of the fault is locked, the compressor no longer
go out to restart regardless of the coil temperature whether or not to resume.
15)． Anti-freeze protection in cooling model
