Central air conditioning cold water flow switch from how to solve the protection
2. Eliminate the "1" effect is still not closed, is the water switch in the drive board stuck or contact failure; repair or replace the water switch.
1. Whether the normal operation of the pump, according to the import and export water pressure to determine whether the water system and to solve (such as water). The amount of circulating water, the flow switch will naturally close.
Central air conditioning cold water flow switch is a part of the chain protection circuit, start the refrigerant pump after the flow switch is not closed should check:
3. Temporary measures: in the "1" completely normal premise, the first two lines of the flow switch shorted, the failure to eliminate the natural, the unit put into normal operation. But the cold water flow switch is the unit chain protection circuit part, should promptly eliminate the fault, put into the monitoring operation to ensure safe production. for reference only
