  • Estimated Lead Time: 6-8 Weeks

  • Manufacturer: Honeywell

  • T678D1020/U

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

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

  • 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.
