Honeywell T991A1764 Temperature Control 0-100F 24' Cap Average 135 ohm

T991A Proportional Temperature Controllers provide modulating control of water or air temperatures in ducts, tanks, and similar applications. Standard models have a coiled sensing element that operates at least four times faster than standard controllers, depending upon operating conditions.

Features

• Fast response models (for duct mounting) have coiled sensing element giving at least four times faster response than standard models.
• Ambient temperature compensated for the case and tubing.
• Sensing element capillary tubing allows remote mounting of sensing element.
• Setpoint may be read and adjusted through cover.
• Throttling dial inside case adjusts proportional throttling range.
