In this section, you can customise the mixing valve operating mode in order to adapt the mixing to the type of system and obtain
correct delivery temperature control.
The parameters to be set are the following:
PB: (min 2 °C- max 10 °C) Proportional band in °C. This value
represents the interval within which the mixing valve
intervenes by means of a PID logic. Outside of the PB,
the mixing valve performs an action equal to 20% of
the motor stroke.
DB: (min 0 °C- max 2 °C) dead band in °C (band where the
mixing valve performs no action).
IT: (min 10sec -max500 sec) Integral Time (PID calculation
integration time).
K: (min 0- max 10) Approach speed towards the calculated
temperature.
The general trend of the measured temperature is
represented in the figure below.

In this section you can enable the dynamic compensation to
calculate the delivery temperature by means of the Enable (Yes
/No) variable. Enabling the dynamic compensation provides
for the allocation of a pilot zone, which affects the delivery
temperature value obtained through the compensation line.
To identify this "Pilot Zone", the identification number of the
zone in the room sensor configuration (see step 4: Zone configuration).
The dynamic compensation modifies the delivery temperature according to the difference
between the sample room temperature and the set temperature setpoint. Its use helps
reaching a pleasant temperature in the shortest time possible.
