"RE" - HISTORY RESET
By pressing the Ok button for 3 seconds it will be possible to delete all the faults stored in the History Menu: the card will automatically exit the Service Menu, in order to
con
fi
rm the operation.
Press the Ok button for 3 seconds to return to the Service Menu.
9 INDICATIONS DURING OPERATION
The controller indicates the boiler operating mode and its faults through the incorporated display: "St" means Standby (no request in progress), "CH" means that the zone
controller requests activation of heating mode, "dH" means Domestic Hot Water production. The fault codes are:
F70
NTC sensor fault (T1)
Short circuit / Contact open
F71
NTC sensor fault (T2)
Short circuit / Contact open
F72
NTC sensor fault (T3)
Short circuit / Contact open
F73
NTC sensor fault (T4)
Short circuit / Contact open (Only with Sliding Temperature enabled)
F74
Communication with boiler board (BLR) not present
(Only for "Communicating" con
fi
gurations)
F75
Communication with Remote Control (RT1) not present
(Only with Remote Control connected)
F76
Communication with Remote Control (RT2) not present
(Only with Remote Control connected)
F77
Communication with Remote Control (RT3) not present
(Only with Remote Control connected)
The fault codes are also displayed in the corresponding menu of the Remote Control during normal operation.
9.1 LCD DISPLAY OFF
Make sure the Controller is powered: using a digital multimeter, check the presence of voltage at terminals 5 and 6.
In case of no voltage, check the wiring.
In case of suf
fi
cient voltage (Range 195– 253 Vac), check the fuse FH02 (see
fi
g. 2).
10 ADDITIONAL FUNCTIONS
10.1 FH MODE
The FH mode is automatically activated the
fi
rst time the card is powered or after doing the Autocon
fi
guration procedure. The FH mode must last for a time equal to the
Mixing valve closing Time timer (TSP31): during this time, the circulating pumps (of the heating zones) will be powered; whereas the mixing valves (if foreseen at the time
of Autocon
fi
guration) must be open for a time equal to one third the Mixing valve closing Time timer (TSP31) and subsequently closed for a time equal to two thirds the
Mixing valve closing Time timer (TSP31).
During FH mode the card must not request heat.
In the
fi
rst 5 seconds of FH mode, the display will show the card software version. The Service Menu can be accessed in FH mode . The FH mode can be stopped by
pressing the + button once.
10.2 EQUAL SETTINGS FOR EACH ZONE (TSP30)
This parameter will only be considered if, after Autocon
fi
guration, the zone controller is con
fi
gured to serve two or more heating circuits of the same type. In this case, if
the parameter is equal to 1, all the heating circuits take the settings of heating circuit 1.
10.3 PUMP ACTIVATION WITH CARD IN STANDBY (TSP34)
This parameter will only be considered if, after Autocon
fi
guration, the zone controller is con
fi
gured in "Communicating" mode. In this case, if the parameter is equal to 1: if
the zone card is in standby and the boiler board is activated in heating, the zone controller must activate all the circulating pumps and force open all the connected mixing
valves (if foreseen at the time of autocon
fi
guration).
10.4 HEATING DELIVERY PROBE ENABLING (TSP35)
This parameter will only be considered if, after Autocon
fi
guration, the zone controller is con
fi
gured in “Stand Alone 1 or 2” mode. Set to 0 in case of “Stand Alone 1" con
fi
-
gurations. Set to 1 in case of “Stand Alone 2" con
fi
gurations.
Note: After modifying this parameter, disconnect then reconnect the power to controller FZ4B
10.5 OPERATION WITH BOILER IN FAULT STATUS (TSP36)
This parameter will only be considered if, after Autocon
fi
guration, the zone controller is con
fi
gured in "Communicating" mode. If the parameter is set to 0, board FX4B
requests are stopped in the event of a boiler board fault. If the parameter is set to 1, board FX4B requests are not stopped in the event of a boiler board fault.
Note: After modifying this parameter, disconnect then reconnect the power to controller FZ4B
10.6 LEGIONELLA PROTECTION (TSP37)
This parameter will only be considered if, after Autocon
fi
guration, the zone controller is con
fi
gured to serve a hot water tank. When set to 0, the protection is disabled. When
set between 1 and 7, the parameter expresses the interval in days between one activation and the next: 1 means 24 hours, 7 means 168 hours. After this time, a timer is
activated for 15 minutes, during which the user setpoint is set to the maximum value (65°C).
10.7 BOILER SUMMER/WINTER MODE (TSP38)
This parameter will only be considered if, after Autocon
fi
guration, the zone controller is con
fi
gured in "Communicating" mode. The parameter is normally left at 0. It is set
to 1 only if the board FZ4B is connected to the following controllers: CPD3, CPD4, MF05F or equivalent.
Note: After modifying this parameter, disconnect then reconnect the power to controller FZ4B
