Product Description
Honeywell T678A1437 Remote Temp Control, 0°F-100°F Range, 2 SPDT, Copper Bulb, 5 ft. Capillary, Switch: 3°F Fixed/Interstage: 3°F-10°F Adj.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.
