Can I open the driveway gate or some other auxiliary function via the buttons on the Vimar monitor?

Yes, you can use buttons A and C on the monitor to control additional functions. The A-button can control an external 12 VDC or 15 VAC coil relay connected to terminals 4 and 6 of of the 01961 module.The C-button can control an external 12 VDC or 15 VAC coil relay connected to terminals 6 and 7 of of the 01961 module. For the C-button, verify the type of feature enabled (if Self-start is on). For an external relay, you can use ELVOX part no. 170/001.
