• Error history
6800 to 6818
The controller saves the last 10 faults which have occurred to a non volatile memory. Any new en-
try will delete the oldest entry from the memory. A fault code and a time are saved for each fault.
Error code list:
– Designation of error:
The error designations in the table below are displayed in plain text on the user interface.
– Location:
The sensor or contact associated to the error message.
– Reset:
Reset is either automatic or manual, depending on the type of error. (For error message, refer to
the table below.)
• Manual reset:
Errors which are displayed in the Info section and accompanied by the Reset question can be
manually reset. Press the OK key once, "yes" flashes on the display. Press the OK key again
to confirm the "yes" and the error will be reset.
• Automatic reset:
Automatic cleaning occurs after a previously set time (OEM setting) has elapsed. After this
time out (6 hours by default) has elapsed, the controller will attempt to reset the error. If "Num-
ber" appears in the table, it is possible to define the how many times the fault can be reset
before the heat pump is declared out of order.
– Heat pump operation:
Shows whether or not the heat pump can continue to operate when the error occurs.
• Yes:
The heat pump continues to operate despite the error message.
• No:
The error interrupts operation of the heat pump.
• No with glycol water:
The error stops glycol water heat pumps, but does not prevent operation of water or air heat
pumps.
• No with water:
The error stops water heat pumps, but does not prevent operation of glycol water heat pumps.
• No with air:
The error stops air heat pumps, but does not prevent operation of water heat pumps or glycol
water heat pumps.
• Per diagrams:
The heat pump will be stopped according to the current installation diagram.
– Priority
Errors are ranked by priority. From priority 5 onward (i.e. priority levels 5 to 9) the alarm mes-
sages used in remote controller are sent. In addition, the alarm relay is switched on.
