Natural Series FAQs

How does the optional rain sensor work?

When the rain sensor detects rain, the control will override the normal on/off duration settings and completely close the curtains until there has been no rain detected for 15 minutes.

How can I update NVC-2 firmware?

Update updated to the latest firmware version using a USB drive. See Updating the firmware in the user manual for more information.

I see hysteresis for the heater. Is there hysteresis for the curtains?

Yes. The idle band acts as the hysteresis for the curtains.

Can I manually override the curtains?

Yes. There is a software manual override that can be accessed through the NVC-2 menu. See Using manual override mode in the user manual for more information. If you require a hardware override, check out the MOB-4.

How big is the control?

The enclosure is 4.75 x 7.80 x 3.75 in. (12 x 15.6 x 9.5 cm)
