A \u003cstrong\u003ereverse-acting\u003c\/strong\u003e thermostat \u003cstrong\u003edecreases its branch output pressure as room temperature rises\u003c\/strong\u003e, which is the opposite response of the \u003cstrong\u003edirect-acting TK-1001\u003c\/strong\u003e heating thermostat, and it is used for \u003cstrong\u003ecooling-duty control loops\u003c\/strong\u003e. The \u003cstrong\u003eTK-1101\u003c\/strong\u003e has a \u003cstrong\u003e55 to 85 degree F dial\u003c\/strong\u003e and a \u003cstrong\u003esetpoint slider\u003c\/strong\u003e behind a small window, and it is built to run on \u003cstrong\u003e15 or 20 psig\u003c\/strong\u003e clean, dry, oil-free \u003cstrong\u003esupply air\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eInside the cover a \u003cstrong\u003etemperature-sensitive element\u003c\/strong\u003e positions the mechanism that sets the \u003cstrong\u003ebranch pressure\u003c\/strong\u003e. The \u003cstrong\u003eblack main tube\u003c\/strong\u003e brings \u003cstrong\u003esupply air\u003c\/strong\u003e in and the \u003cstrong\u003ewhite branch tube\u003c\/strong\u003e sends the \u003cstrong\u003econtrolled pressure\u003c\/strong\u003e to the \u003cstrong\u003evalve or damper actuator\u003c\/strong\u003e, both through \u003cstrong\u003e5\/32-inch spring-reinforced plastic tubing\u003c\/strong\u003e. The \u003cstrong\u003ethrottling range\u003c\/strong\u003e is adjustable from \u003cstrong\u003e2 to 10 degrees F per 10 psi\u003c\/strong\u003e, set at the factory to \u003cstrong\u003e4 degrees F per 10 psi\u003c\/strong\u003e, so you can \u003cstrong\u003etune the response\u003c\/strong\u003e to a \u003cstrong\u003etight or loose loop\u003c\/strong\u003e without \u003cstrong\u003ecycling\u003c\/strong\u003e. \u003cstrong\u003eAir consumption\u003c\/strong\u003e is \u003cstrong\u003e13.8 scim\u003c\/strong\u003e, \u003cstrong\u003eair capacity\u003c\/strong\u003e is \u003cstrong\u003e16 scim\u003c\/strong\u003e, and the \u003cstrong\u003eoutput signal\u003c\/strong\u003e runs from \u003cstrong\u003e0.5 psig\u003c\/strong\u003e up to \u003cstrong\u003esupply pressure minus 0.5 psig\u003c\/strong\u003e. The thermostat is rated for \u003cstrong\u003eoperating ambient\u003c\/strong\u003e of \u003cstrong\u003e40 to 150 degrees F\u003c\/strong\u003e, with a \u003cstrong\u003emaximum supply pressure\u003c\/strong\u003e of \u003cstrong\u003e30 psig\u003c\/strong\u003e.
