Remote Temp Control, 55F-90F Range, 2 SPDT, Copper Bulb, 5.5 ft. Capillary, Switch: 2F Fixed/Interstage: 2F Diff.

Overview

Remote bulb thermostats regulate temperature of air or liquids in ducts, pipes, tanks and boilers.

Features

• Suitable for applications requiring temperature control of air or liquids where controller must be placed outside the sensing area.
• Typical uses include control of dampers and valves in heating, cooling and heating-cooling systems.
• Fast response models (available for use in return air duct) operate approximately four times faster than standard models.
• Controller can be mounted in any position. 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.
• T678 models have a maximum connected load of 2000 VA.
