developed for controlling ventilation systems. The panel communicates with the PI
Air2 system via a Modbus interface, ensuring easy installation.
Product:
PI-HMI
Type:
3,5“ t ouchscreen panel
This quick start guide only de-scribes basic settings. If the screen saver is active,
simply touch the screen once to open the home screen.
This screen provides access to elementary functions such as fan speed, temperature
and setup. The time and day of the week are shown in the top line of the screen.
Below these, an alarm bell is visible if an alarm has been activated. The house in the
middle section of the screen provides access to a simple overview of temperatures,
air volumes and filter pressures. The temperature shown to the right of the house is
the temperature setpoint. The icons shown in the lower part of the screen can be
changed and may therefore differ from those shown in these instructions.
To set fan speed, press the fan in the lower part of the home screen. You can choose
between
six
predefined fan speeds. Off, Auto, Low,
Medium,
High and Service Stop.
If you choose Auto, PI-HMI will follow a predefined program. If you choose Low, the
predefined program is overridden and the fan operates at low speed.
If you choose
Medium, the predefined program is overridden and the fan operates at medium
speed.
If you choose High, the predefined program is overridden and the fan
operates at high speed.
If you choose Off, the fan comes to a complete standstill until
fan speed is again changed. If you choose Service Stop, the system shuts down and
can only be restarted locally from the control panel.
