The algorithm remains the same as the confi guration: 5.26 "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.

6.1.1 On/Off Thermostat
Zone pump
System circulation (including boiler) is ensured by the zone circulating pump: therefore the boiler does not have to have the circulating pump.
Zone valve
System circulation (including boiler) is ensured by the boiler circulating pump: therefore the boiler must have the circulating pump.
Algorithm
a. Zone card Heating Setpoint = Zone1 Heating Setpoint
b. Zone1 Heating Setpoint = Zona1 Max.Temperature (TSP02) + Zona1 calculated setpoint Offset (TSP03).
c. If RT1 closes the contact, RY1 must be powered; and must remain powered while RT1 remains closed.
The Delay for Zone timer (TSP29) starts: during this time the relay of card SK must be unpowered.
d. At the end of the Delay for Zone timer (TSP29), the Heating standby Time timer (TSP33) must be reset.
If T3 is lower than the Zone card Heating Setpoint value, the relay of card SK must be powered.
If T3 becomes higher than the Zone card Heating Setpoint value plus the Heating Hysteresis value (TSP32), the relay of card SK must be unpowered and, at the
same time, the Heating standby Time timer (TSP33) must start.
At the end of the Heating standby Time timer (TSP33), if T3 is lower than the Zone card Heating Setpoint value, the relay of card SK must be powered, otherwise
the latter will be powered as soon as T3 is lower than the Zone card Heating Setpoint value.
e. If RT1 opens the contact, the relay of card SK must be unpowered; whereas RY1 must remain powered for the entire duration of the Post-circulation Time timer
(TSP27); at the end of this timer, RY1 must be unpowered.
6.1.2 Remote Control
Zone pump
System circulation (including boiler) is ensured by the zone circulating pump: therefore the boiler does not have to have the circulating pump.
Zone valve
System circulation (including boiler) is ensured by the boiler circulating pump: therefore the boiler must have the circulating pump.
Algorithm
a. Zone card Heating Setpoint = Zone1 Heating Setpoint
b. Zone1 Heating Setpoint = Control Setpoint calculated from Remote Control + Zone1 Calculated setpoint Offset (TSP03).
The Control Setpoint calculated from Remote Control is limited by ID57 of the Remote Control itself (Heating temperature adjustment button).
The range for management of the Remote Control ID57 is defi ned by the parameters: Zone1 Min. Temperature (TSP01) and Zone1 Max. Temperature (TSP02).
c. If RT1 activates the request, RY1 must be powered; and must remain powered while RT1 remains in request status.
The Delay for Zone timer (TSP29) starts: during this time the relay of card SK must be unpowered.
