When the window contact is active, (open window
= energy reduction activated), the heating and
cooling setpoints are automatically those of the
building protections. The ventilation status switches
to automatic mode and, after exiting the energy
reduction mode, returns to its previous status.
When the function is active, its symbol is
automatically visible in the screen’s footer if it has
been selected. The control operates at the setpoints
of the building protection systems.
When the Change-Over contact is active, heating or cooling modes are forced on a 2-pipe unit.
If the input is configured as a contact, heating mode is allowed with an open contact and cooling mode with
a closed contact.
The in-use function can be activated via the configuration of a digital input (address 18 or 19) or via Modbus
(address 257).
If the button and Modbus are used at the same time, the last modified value determines the output value.
The digital input has the highest priority.
When the in-use function is active, its symbol is automatically visible if it has been selected in the footer.
