One Mixed Zone And One Hot Water Tank - With External Sensor - Gruppo Ferroli FZ4B Instrucciones De Uso E Instalación

EN
In case of simultaneous request, the Zone card Heating Setpoint is equal to the higher of the two: Zone1 Heating Setpoint and Hot water tank Primary Setpoint
(TSP23).
If the circuit (Heating or Hot water tank) that ends the request has the higher Setpoint, the Zone card Heating Setpoint must be immediately decreased until it is equal
to the Setpoint of the circuit (Heating or Hot water tank) still in request status.
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.
6.24.2 Remote Control
The algorithm of the Mixed Zone remains the same as the confi guration: 6.7 "ONE Mixed Zone – No External Sensor".
The algorithm of the Hot water tank remains the same as the confi guration: 6.17 "ONE Hot water tank".
What changes is:
a. DHW has priority over Heating: the Hot water tank Priority parameter (TSP25) is equal to 0.
During DHW mode, the algorithm of the Hot water tank has the highest priority.
During 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.
In case of simultaneous request, the Zone card Heating Setpoint is equal to the higher of the two: Zone1 Heating Setpoint and Hot water tank Primary Setpoint
(TSP23).
If the circuit (Heating or Hot water tank) that ends the request has the higher Setpoint, the Zone card Heating Setpoint must be immediately decreased until it is equal
to the Setpoint of the circuit (Heating or Hot water tank) still in request status.
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 Control (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 Control; the zone card
takes the last modifi ed value and must update both.
f. DHW Eco/Comfort
In Economy mode the DHW request generated by T2 is disabled.
In Comfort mode the DHW request generated by T2 is enabled.
