Honeywell Proportional Temperature Controller - T991A1426/U

The Honeywell Proportional Temperature Controller stands out for its precise control functionality within the temperature set-point range of 0 to 100 degrees Fahrenheit. The controller is equipped with a copper bulb sensor element that measures 1/2 inch in diameter and 4-3/16 inches in length. Its unique design includes a 135 ohm potentiometer and a 5-feet capillary.

This model offers a fast response feature specifically designed for duct mounting applications. The coiled sensing element enables a response time that is four times faster than standard models, significantly enhancing performance. The controller is also ambient temperature compensated, resulting in accurate readings that take into consideration the conditions of the case and tubing.

Apart from the standard features, the design incorporates a sensing element capillary tubing that allows remote mounting of the sensing element. This feature provides more flexibility in terms of installation and use. The set point, easily read and adjusted through the cover, ensures optimum comfort and control. The unit also includes a throttling dial located inside the case, offering an adjustable proportional throttling range for even more control over your systems' temperature management.
