Overview

Proportional (135 ohm) remote bulb controllers for ducts, tanks, boilers, pipes and other heat exchangers.

Features

  • Provide proportioning control of three-wire, low-voltage valve or damper motors.
  • Used to regulate temperatures of either air or liquids.
  • All models ambient compensated. Ambient temperature compensation provides good temperature control. Refer to T775 Electronic Remote Temperature Controller where more exact control is required and/or remote controller location is preferred.
  • Temperature setting scale markings in both Fahrenheit and Celsius. Steel case has a clear plastic cover to make setting readily visible.
  • Surface mount using two screws through back of case.
