Errors

States and errors

Section - Status Errors
 

Code of states and errors 

- four-digit code (read from left)

 

1. digit:  1 - Freeze protection (output water temperature dropped below safe limits)

 

 

2 - Insufficient water flow (water flow dropped below safe limits)

 

 

3 - Outdoor unit disorder

 

 

4 - Low water pressure (water pressure dropped below 0,9 Bar)

 

 

5 - Faulty temperature sensor MX (communication unit) 

 

2. digit:  1,2 - Faulty output water temperature sensor

 

 

3,4 - Faulty input water temperature sensor

 

 

 

 

 

3. digit:  1,2 - Faulty pool temperature sensor

 

 

3,4 - Faulty secondary circuit temperature sensor 

 

4. digit:  1,2 - Faulty outdoor temperature sensor 

 

 

3,4 - Faulty object temperature sensor

 

 

5,6 - Faulty DHW temperature sensor

 

 

7,8 - Faulty accumulatice tank temperature sensor

 

First two digits from left indicate critical error, in which is heat pump operation stopped or limited.

 

Autoreset

 - Function of error autoreset. If the error disappears, heat pump is again put into 

operation.  This could happen maximum 5 times, autoreset function is deactivated thereafter.

 

Error history

- Error history records last 10 errors.
