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