CONTROLLO ZONE FZ4B

cod. FZ4B - 06/2011 (Rev. 00)
EN
If the zone that starts the request has a higher Heating Setpoint than the zone already in request status, the Zone card Heating Setpoint must be immediately increased
until it is equal to the higher Heating Setpoint of the zone in request status.
b. Each zone has its own adjustment parameters.
c. Post-circulation time
This must be carried out only on the last zone that ends the request.
Also, if the last zone in request status is doing post-circulation and another zone starts its own request, post-circulation must be stopped: so that there is always and
only a single zone in post-circulation.

The algorithm remains the same as the con fi guration: 6.3 “TWO Direct Zones – 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.

The algorithm remains the same as the con fi guration: 6.3 “TWO Direct Zones – No External Sensor”.
What changes is:
a. The calculation of Zone card Heating Setpoint
In case of simultaneous request, the Zone card Heating Setpoint is equal to the highest of the three: Zone1 Heating Setpoint, Zone2 Heating Setpoint and Zone3
Heating Setpoint.
If the zone that ends the request has the highest Heating Setpoint, the Zone card Heating Setpoint must be immediately decreased until it is equal to the Heating
Setpoint of the zone still in request status.
If the zone that starts the request has a higher Heating Setpoint than the zone already in request status, the Zone card Heating Setpoint must be immediately increased
until it is equal to the higher Heating Setpoint of the zone in request status.
b. Each zone has its own adjustment parameters.
