9.3. V3V hot output (AO1 - 0-10V)
Only for Zehnder Eversky PREMIUM BC or INFINITE BC.
The operation of analogue output AO1 is associated with the operation of the digital output DO3.
The signal of the analogue output AO1 is 0-10V. It reflects the heating requirement calculated by the controller of the
unit according to the programmed temperature setpoint and the actual temperature measurement via a PI (proportional/
integral) control loop:
This signal can be used, for example, to control an external device (modulating 3-way valve, heating system, etc.) that
provides heating for the room, with the central ventilation unit acting as a room thermostat.
