minimum threshold limit delay time
Possible settings:

Delay time to switch-off the HYDROVAR in case the actual value drops below the min.
threshold limit or a connected external low water protection at terminals X3/11-12 has
been opened.

The min. 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.

0615 ERROR RESET
ON
Automatic error reset
Possible settings:
ON – OFF
ON:
Allows an automatic restart for 5 times in case of a failure. If the failure is still active
after the 5
th
restart, the HYDROVAR will shut off and the appropriate error message is
shown.
The internal counter of the automatic error reset is decreased by 1 after each operating
hour, so if an error could be reset after 3 restarts, there are 3 further restarts possible after
one hour, 4 after two hours and 5 automatic restarts after 3 operating hours.
A manual reset can be done by switching an external ON/OFF (X3/7-8) contactor.
Not each error can be reset automatically.
(For detailed information see chapter 11 failure messages)
OFF:
if the ERROR RESET is set to OFF, each failure would be shown on the display directly
and must be reset manually.
