T915 Proportional Temperature Controller

Type: Remote bulb

Application: Used with Series 90 Modutrol Motors for proportional control of valves and dampers

Dimensions, Approximate: 5 1/2 in. high x 4 1/2 in. wide x 2 3/4 in. deep (140 mm high x 114 mm wide x 70 mm deep)

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

Bulb Size: 1/2 in. diameter x 4 in. long (13 mm diameter x 102 mm long)
