Temperature Controllers

T915 Proportional Temperature Controller

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

• 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

Typ e: Remote bulb Application: Used with Series 90 Modutrol Motors for proportional

control of valves and dampers
