Honeywell T991A1079 Proportional Temperature Controller

For modulating control of water or air temperature in ducts, tanks and similar applications.

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.
