Overview

High capacity, single/dual input pneumatic controller, used in conjunction with remote sensors, to provide proportional (P) or proportional plus integral (P+I) control of temperature, humidity, pressure, or dewpoint for heating and air conditioning.

Features

  • Proportional plus integral control option minimizes offset.
  • Miniature diaphragm technology provides high degree of accuracy and reliability.
  • Direct Acting models can be converted to Reverse Acting (RA) function in field.
  • Field adjustable compensation start point.
  • Local or remote setpoint field option. Integral action cut-off provides trouble-free automatic startup.
  • Transparent cover (optional) provides protection while allowing easy reading of settings and gages.
  • Corrosion resistant construction.
