1. Overview
Now you can use the newest and most modern gauge with features such as Touch Screen, two way
communication with laptops locally or over the Internet, WiFi and advance FanTestic software.
Fans manufactured by TEC (such as those used with the Minneapolis Duct Blaster® or Minneapolis
Blower Door™ Model 3 or 4) can be controlled by the Fan Speed control output on a Retrotec gauge
using the Retrotec Model FN275 - Speed Control Adapter (for TEC fans). The fan speed control must
have the cruise input port which is indicated by the presence of an audio jack on the side.
