EN
If the circuit (Heating or Hot water tank) that starts the request has a higher Setpoint than the circuit already in request status, the Zone card Heating Setpoint must
be immediately increased until it is equal to the higher Setpoint of the circuit (Heating or Hot water tank) in request status.
c. Each zone has its own adjustment parameters.
d. Post-circulation time
During DHW mode, if the pump of the zone is doing post-circulation, the latter must be stopped whereas the mixing valve must be controlled in closing for the entire
duration of the Mixing valve closing Time timer (TSP31). At the end of DHW mode, post-circulation must not restart.
e. DHW setpoint
The range for management of ID56 of the Remote Controls (DHW temperature adjustment button) is between 10°C and 65°C: zone card fi xed ranges.
Modifi cation of the DHW Setpoint occurs in parallel: through the Hot water tank Setpoint parameter (TSP26) or through ID56 of the Remote Controls; the zone card
takes the last modifi ed value and must update the others.
f. DHW Eco/Comfort (1 Remote Control)
In Economy mode the DHW request generated by T2 is disabled.
In Comfort mode the DHW request generated by T2 is enabled.
g. DHW Eco/Comfort (plus 1 Remote Control)
The DHW request generated by T2 is enabled only if all the Remote Controls are in Comfort mode.

The algorithm remains the same as the confi guration: 6.26 "ONE Mixed Zone, ONE Direct Zone and ONE Hot water tank – No External Sensor".
What changes is only the calculation of Zone1 Heating Setpoint and Zone2 Heating Setpoint if the sliding temperature was activated in one or both zones.

7 "COMMUNICATING" CONFIGURATIONS

The number of these confi gurations and their algorithms remain the same as the "Stand Alone 1" confi gurations; what changes is the way in which controller FZ4B requests
heat. In place of card SK, there will be the OpenTherm connection with the boiler board (BLR).
The variable defi ned Zone card Heating Setpoint, which in "Stand Alone 1" confi gurations is used to activate or deactivate the relay of card SK, will be sent to the boiler
board as Control Setpoint.

7.1 "COMMUNICATING" CONFIGURATIONS WITH DHW (INTEGRATED IN BOILER)

a. DHW has priority over Heating: the parameter zone pump Status with boiler in DHW mode (TSP28) is equal to 0.
When the boiler is in DHW mode, the zone request (if occurring) must be stopped without doing post-circulation and the mixing valve must be controlled in closing
for the entire duration of the Mixing valve closing Time timer (TSP31). If DHW mode ends before the end of the Mixing valve closing Time timer (TSP31), the timer
must be reset, because at the end of DHW mode the zone request (if occurring) must restart with the normal algorithm.
b. DHW does not have priority over Heating: the Hot water tank Priority parameter (TSP25) is equal to 1.
The controller will not change anything while boiler is in DHW mode.

8 SERVICE MENU

Press the Ok button for 5 seconds to access the zone controller Service Menu. Press the + and - buttons to select "tS", "In", "Hi" or "rE. "tS" means Transparent Parameters
Menu, "In" Information Menu, "Hi" History Menu (of the zone controller), and "rE" History Menu Reset (of the zone controller). After selecting the Menu, press the Ok button
to access it.
