0570 MSTPRIORITY
Master priority (for cascade serial / synchron only!)
ON
Possible settings: ON - OFF
This parameter determines the alternation order when Master and Basic Inverters are used within one
system. In such a case you have to select if either the master or the Basic Inverters should be switched on
first.
ON - all Master Inverters in the system start (unless it is stopped manually or by a failure) before the first
Basic Inverter runs.
For example: Address 1-3.......Master Inverters
Address 4-8……Basic Inverters
Switching order: Adr 1 Adr 2 Adr 3 Adr 4 Adr 5 Adr 6 Adr 7 Adr 8
Master Master Master Basic Basic Basic Basic Basic
OFF - One master (which controls the overall system) is running. With rising consumption all Basic Invert-
ers are turned on before other Masters run.
Switching order: Adr 1 Adr 4 Adr 5 Adr 6 Adr 7 Adr 8 Adr 2 Adr 3

Minimum threshold limit

Possible settings: disabled - max. SENSOR RANGE
• An adjusted value >0.00 has to be reached within the programmed DELAY TIME [0610]
• If this value can’t be reached, the HYDROVAR stops with the failure message ”MIN. THRESHOLD ERROR”.
• To disable the minimum threshold limit, press ▼ till “disabled” is shown on the display.
0610
0610 DELAY - TIME
Minimum threshold limit delay time
2 Sec
Possible settings: 1 – 100 sec
Delay time to switch-off the HYDROVAR if the actual value drops below the minimum threshold limit or a
connected external low water protection at terminals X3/11-12 has been opened.
Notice: The minimum threshold function is also active during start up of the pump! Therefore the delay
time has to be set higher than the duration that is needed, to reach a value above the limit.
