Commercial Building Controls : Standalone Controllers : Temperature Controllers : T991A : T991A1079/U
Modulating Temperature Controller, 160 - 260 F. 20' copper element. max. Operating Temperature: 280F
Overview
Proportional (135 ohm) remote bulb controllers 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.
