threshold limit or a connected external low water protection at terminals X3/11-12 has
been opened.

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.
