Pretection of compressor postpones 3 minutes, both compressor turn on and off need 3 minutes. every time,
compressor needs 3 minutes to restart after it stoped.

Water flow switch protection (hydronic heating system use it ). After press

key, and cycle water pump
run, if water flow switch off, then compressor and fan off.

High exhaust temperature pretection: when exhaust temperature
≥
115
℃
and last 30s, system consider
temperation is too high, close output, display error code, 3 minutes later system can restart.

High pressure protection
：
when high pressure switch disconnect 3 times within an hour, display panel show error
code and alarm. Then compressor off, fan off, cycle water pump off. After high pressure switch recover ,
postpone 3 minutes ,compressor restart, If high pressure switch disconnect over 3 times within an hour, control
panel lock the error, turn off all output signal, and will not restart whether pressure switch will recover or not.
5
、
Low pressure protection. when low pressure switch disconnect 3 times within an hour, display panel show error
code and alarm. Then compressor off, fan off, cycle water pump off. After low pressure switch recover, postpone
3 minutes, compressor restart. If low pressure switch disconnect over 3 times within an hour, control panel will
lock the error, close all output signal, and will not restart whether pressure switch will recover or
not..(Remarks:when defrosting, or within 5 minutes after compressor startup, system doesn’t test low pressure
switch)

、
Sensor error: if sensor occure error(broken circuit or short circuit), all output stop, and show error code. Sensor can
restart after erroe disappear.

Three phase protection
：
when dial switch 1 select number side, it has three phase test function, it will test three
