Priority

The operating priorities the control unit follows are:

1. "Permanent" group override.
2. “Temporary" and "Permanent" override of the single (privileged)

controllers.

3. "Temporary" group override.
4. Vacation period programme.
5. Holiday programme.
6. Weekly schedule.

Summer/winter changeover

The control unit is provided with 4 inputs in order to set
summer/winter operation for each group.

The open contact corresponds to winter set up.

Cooling and heating qualifications

The control unit is provided with an input (two terminals), so as to
inhibit the cooling action for the whole system (closed contact =
cooling inhibited), and with four inputs (five terminals) inhibiting the
heating action in each group
When the actions are inhibited, the corresponding actuators are
closed independently from the set mode.

Storage of programmed data

Programme data are stored on a memory (TimeKeeper) and remain
the same even if the power supply is absent.

Connection with controllers

Instructions and information between the control unit and the
controllers are exchanged through an intelligent two-lead polarized
"BUS" connection.
The RS485 serial communication type is particularly indicated for its
