DSTAT-1
For intermittent high speed operation, connect Nu-Air PN DSTAT-1,
dedicated (RNC) wall switch, CO

sensor, etc. to R and Hi terminals.
For continuous low speed, connect jumper wire to R and LO
terminals.
Where required, C terminal may be used for controls requiring
external 24 VAC power source.
For two-wire switching, and where local building regulations permit,
Nu-Air recommends a jumper wire between R and SB to engage the

Standard Dehumidistat (Part # DSTAT-1) & 2-wire switches
The dehumidistat switches the HRV to high speed when the relative humidity of the air around it
exceeds its set point until indoor humidity falls below the set point.

Windsor Control (Part # WIN-1)
The Windsor Dehumidistat Control provides the same humidity control as the Standard
Dehumidistat, with the added functionality of a 3-position switch from which the operator can
select three operating modes. The Constant switch can be engaged for full-time high speed.

Install in bathrooms, kitchens, workstations or other locations where high-speed ventilation
control is needed. The machine will run at high speed for twenty (20) minutes and then return to
