- Adjustable humidity set points between ~50% to ~90% RH
- White Grille
- Includes 6" to 4" duct reducer
- Energy efficiency at 15.4 CFM/Watt
- Blue and amber LED indicator lights to show humidity sensor and full speed modes

Delta Breez VFRU-25-34MS – Frequently Asked Questions
1) What fan does the Delta Breez VFRU-25-34MS motion sensor work with?
The VFRU-25-34MS is the motion sensor module built for the Delta Breez SIG80-110MH fan in the BreezSignature line. It is a sensor accessory for that specific fan, not a universal occupancy switch, so it belongs on a SIG80-110MH opening rather than on another brand's exhaust fan.
2) How does the motion sensor behave when someone walks out of the bathroom?
Motion puts the fan at full speed. After the room clears, it holds full speed for a 20 minute delay, then drops into humidity control mode rather than shutting off. In humidity mode, anything above the set point runs full speed and anything below runs continuously at a preset lower level of 0, 30, 50, 60 or 80 CFM. For multifamily or hotel bathrooms, that means the fan keeps pulling moisture after the guest leaves without anyone touching a switch.
3) What duct size does this Delta Breez sensor grille assembly work with?
It covers 4 inch to 6 inch duct. A 6 inch to 4 inch duct reducer is included, so you can tie into existing 4 inch flex in a remodel or run 6 inch on new construction for lower static pressure without sourcing a separate fitting.
4) Can I set the humidity trigger point on the Delta Breez motion sensor?
Yes, the set point is field adjustable from roughly 50% to 90% RH. Dry climates or well conditioned buildings usually run near the low end so the fan responds early to a shower; humid coastal jobs get set higher to keep the fan from running constantly. Blue and amber LEDs on the grille show which mode is active, humidity sensing or full speed.
5) Is the Delta Breez SIG80-110MH motion sensor Energy Star rated?
Yes, it carries an Energy Star listing, and the fan it serves moves 15.4 CFM per watt. For code jurisdictions and green building programs that require Energy Star rated ventilation, that rating is on record for this assembly.
6) What color is the grille, and how big is it?
White grille, 7-7/8 inches in height. Standard white matches typical ceiling finishes across a unit, which matters when you are standardizing bath ventilation across a whole building.
7) Is there an installation manual for the Delta Breez VFRU-25-34MS?
Yes. Delta publishes both an installation manual and a submittal sheet for the SIG80-110MH assembly, and both are posted with the product. The submittal sheet is what you hand to an engineer or inspector when the ventilation spec has to be approved before rough-in.
