In this application note the e-Room Plus device is configured in Office Sunblinds mode and provides a 2 pipes system HVAC control and an automated curtains / sunblinds management. The HVAC system is directly controlled through the device pushbuttons, or it can also be remotely controlled through its standard communication bus. The HVAC system is done in stand-alone mode on the device, managing its outputs automatically for the valve actuator control and the fan-coil speed on demand. Opening the window stops the HVAC system temporarily, activating it again when it is closed. The raise and lower curtain pushbuttons are directly connected to the device, like the two relays output that control both motor directions. The device includes timeout raise/lower limit switch configuration variables that can be changed through the bus depending on each installation.
Any HVAC control function and curtain/sunblinds automated position control function are available through the communication bus for a global Building Management System remote control.
Main features of this application note:
- 2 Pipes installation
- On/Off valve control
