13.6  Indoor Unit Safety 

13.6.1  Indoor Unit Safety Control 

1  When water pump is ON, the system will start checking flow switch status (ON/OFF). 
2  If the flow switch ON for 10 seconds, the system will check on the water inlet temperature for 10 seconds. 

If the water inlet temperature not exceeds 80°C, the water pump shall be continuously running with normal 
mode. 
If the water inlet temperature exceeds 80°C for continuously 10 seconds, the water pump will be OFF 
immediately. 

3  After water pump OFF for more than 10 minutes, it will be ON back and the indoor unit safety control 

checking is restarted. 

 

 

 

13.7 Auto 

Restart 

Control 

1  When the power supply is cut off during the operation of Air-to-Water Heatpump, the compressor will re-

operate after power supply resumes.
