E 654
INVERSION: OPPOSITE
CODE GENERATED BY : With valve not active, the end-of-range micro-switch is actuated (i.e. is open electrically) on the other side
to that expected by the board.
RESET METHOD : Contact Robur TAC.
E 655
INVERSION: UNKNOWN
CODE GENERATED BY : With valve not active, neither of the two end-of-range microswitches is actuated (i.e. are both closed
electrically).
RESET METHOD : Contact Robur TAC.
E 656
INVERSION: UNCERTAIN
CODE GENERATED BY
: With valve not active, both of the two end-of-range microswitches are actuated (i.e. are both open
electrically).
RESET METHOD
: Contact Robur TAC.
U
678
HIGH HOT OUTLET WATER TEMPERATURE
CODE GENERATED BY : High hot outlet water temperature.
RESET METHOD : Reset occurs automatically when the condition that generated the code ceases.
U
679
ANTIFREEZE FUNCTION ACTIVATED (heating mode)
CODE GENERATED BY : Antifreeze function activated (with function enabled: see menu 1, Parameter163; and only with machine
off).
Activation occurs when the hot Inlet or outlet water temperature falls below 39.2°F (in this case, the
function signals that the plant water circulator has been switched on). If this temperature falls further to
below 37.4 °F, the function also activates the flame control unit.
RESET METHOD : The code clears automatically if, with only the circulator on, the hot Inlet or outlet water temperature
returns to above 41.0 °F (in this case the circulator switches off); or, if also the flame control unit has
switched on, when this temperature reaches 64.4 °F (in this case the flame control unit and then the
circulator switch off).
U
680
INCOMPLETE PARAMETERS
CODE GENERATED BY : Incomplete parameters.
RESET METHOD : The code remains until operating parameters are entered and completed. Contact Robur TAC.
NB: If the board is replaced the Code E 80 may appear, meaning that the GAHP-AR characterization parameters have not been set
E 80 / E 680
INCORRECT PARAMETERS
CODE GENERATED BY : Invalid parameters or damage to parameter memory.
RESET METHOD : Reset occurs automatically when correct parameters are entered.
If the code persists, contact Robur TAC. If the parameters are incorrect, it is necessary to enter and
complete the unit operating and characterization parameters. If the memory is damaged it is necessary to
replace the board.
U
681 -
U
682
INVALID BANK 1 DATA - INVALID BANK 2 DATA
CODE GENERATED BY : Invalid Bank 1 data - Invalid Bank 2 data.
RESET METHOD : Reset occurs automatically 5 seconds after the code is generated.
E 681 - and 682
INVALID BANK 1 DATA - INVALID BANK 2 DATA
CODE GENERATED BY
: Invalid Bank 1 data - Invalid Bank 2 data.
RESET METHOD
: Reset may be performed via the board, menu 2, Parameter 1. If the code persists, contact Robur TAC.
U
683
RY and RW CONTACTS ACTIVATED SIMULTANEOUSLY
CODE GENERATED BY : both RY and RW contacts are simultaneously closed.
RESET METHOD : The code clears automatically when at least one of the two contacts opens.
