Description
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.
  • T675A models with fixed differential have an electrical rating of 125 VA at 120/208/240 and 277 Vac.
  • T675B models have 125 VA pilot duty up to 277 Vac.
  • T678 models have a maximum connected load of 2000 VA.
