Honeywell Remote Bulb Temperature Controller - T678A1353/U

The Remote Bulb Temperature Controller from Honeywell is a highly versatile instrument engineered for the precise control of either air or liquid temperatures. It operates within a temperature range of 55 F to 175 F and features a copper bulb sensor element for accurate readings. This controller is especially suitable for applications where it is necessary to place the controller away from the sensing area. Its typical uses include managing dampers and valves for heating, cooling, and combined heating-cooling systems.

This device is equipped with two single pole double throw (SPDT) switch contacts and has the flexibility of being mountable in any position, catering to a wide array of environments and spatial restrictions. With a bulb size of 1/2 in. x 4-3/16 in. and a capillary length of 5 ft, it is adept at handling various industrial and commercial applications. It can easily integrate into 120 VAC or 240/277 VAC systems and provides output through a relay.

One of the key features of the Remote Bulb Temperature Controller is its ambient temperature compensation, ensuring accurate and consistent temperature control under fluctuating ambient conditions. In essence, this Honeywell controller is a sturdy, versatile, and efficient choice for industrial temperature regulation.
