Airstream Temperature Controllers<br />
The T201 series are one-pipe, non-relay controllers designed<br />
primarily for use as low limit thermostats in unit ventilator and central<br />
fan system applications.<br />
Features:<br />
• Rigid or averaging liquid-filled sensing elements.<br />
• Field-adjustable throttling range.<br />
• Simple, straightforward one-pipe (nozzle and flapper) operation (Direct-Acting).<br />
• May be used as primary or low-limit controller.<br />
• Includes gauge-tee and compression restrictor-tee.<br />
