"HI" - HISTORY MENU - The card can store the last 10 faults: the History datum item H1 represents the most recent fault that occurred, whereas the History datum item H10 represents the least recent. The codes of the faults saved
are also displayed in the corresponding menu of the Remote Control. Press the + and - buttons to scroll the list of faults. To display the value of a parameter, press the Ok button after selecting it. Press the Ok button for 3 seconds
to return to the Service Menu. Press the Ok button for 5 seconds to exit the card Service Menu, or exiting occurs automatically after 15 minutes.
"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 confirm the operation.
Press the Ok button for 3 seconds to return to the Service Menu.
5 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 the boiler for 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)
The fault codes are also displayed in the corresponding menu of the Remote Control during normal operation.
5.1 LCD DISPLAY OFF
Make sure the Controller is powered: using a digital multimeter, check the presence of supply voltage at terminals 5 and 6.
In case of no voltage, check the wiring. In case of suffi cient voltage (Range 195– 253 Vac), check the fuse FH02 (see fi g. 2).

6 ADDITIONAL FUNCTIONS

6.1 FH MODE
The FH mode is automatically activated the fi rst time the card is powered or after doing the Autoconfi 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 Autoconfi 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.
6.2 EQUAL SETTINGS FOR EACH ZONE (TSP30) - This parameter will only be considered if, after Autoconfiguration, the zone controller is configured 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.
6.3 PUMP ACTIVATION WITH CARD IN STANDBY (TSP34) - This parameter will only be considered if, after Autoconfiguration, the zone controller is configured 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 autoconfiguration).
6.4 HEATING DELIVERY PROBE ENABLING (TSP35) - This parameter will only be considered if, after Autoconfiguration, the zone controller is configured in "Stand Alone 1 or 2" mode. Set to 0 in case of "Stand Alone 1" configurations.
Set to 1 in case of "Stand Alone 2" configurations. Note: After modifying this parameter, disconnect then reconnect the power to controller FZ4B
6.5 BOILER OPERATION IN FAULT STATUS (TSP36) - This parameter will only be considered if, after Autoconfiguration, the zone controller is configured 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
6.6 LEGIONELLA PROTECTION (TSP37) - This parameter will only be considered if, after Autoconfiguration, the zone controller is configured 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).
6.7 BOILER SUMMER/WINTER MODE (TSP38) - This parameter will only be considered if, after Autoconfiguration, the zone controller is configured 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
6.8 ANTIBLOCKING
6.8.1 Circulating pump antiblocking - After 24 hours of inactivity, the system circulating pumps are activated for 5 seconds.
6.8.2 Mixing Valve antiblocking - After 24 hours of inactivity, the mixing valves must be opened for a time equal to the Mixing valve closing Time timer (TSP31) and subsequently closed for a time equal to the Mixing valve closing
Time timer (TSP31)
6.9 USER SETTINGS - The settings for Heating, such as max. delivery temperature, external probe curve (with optional external probe connected to boiler), weekly time programming, etc., are independent for each zone; these are
modified through the Remote Control of the corresponding temperature zone. In case of direct zones, make sure to set a similar max. delivery temperature for all the temperature zones. With Room Chronothermostats, on closing
of the contact the delivery temperature is adjusted to the max. value set by the zone controller. The settings relevant to DHW, such as DHW temperature, Economy/Comfort mode, weekly time programming (with boiler arranged:
see the relevant documentation), etc., are managed in parallel; these are modified through the Remote Controls of the temperature zones. In case of DHW weekly time programming, the zone controller overlaps programmes
coming from the single Remote Controls.
6.10 EXTERNAL PROBE/SLIDING TEMPERATURE - The connection to the external probe must be made when it cannot be connected to the boiler board.
