    Remote Temperature Controllers

    T675A/B and T678A Temperature Controllers

    T675A/B and T678A temperature controllers regulate the temperature of air or liquids in ducts, pipes, tanks, and boilers. Typical uses include control of dampers and valves in heating, cooling, or heating-cooling systems.

    Overview

    T675A/B and T678A temperature controllers regulate the temperature of air or liquids in ducts, pipes, tanks, and boilers. Typical uses include control of dampers and valves in heating, cooling, or heating-cooling systems.

    Features & Benefits:
    • T675A has one single-pole, double-throw (SPDT) switch that breaks R-B and makes R-W at the setpoint on temperature rise
    • T675B manual reset low limit has one single-pole, single-throw (SPST) switch that breaks at the setpoint on a temperature fall, and requires manual setting
    • T678A has two single-pole, double-throw (SPDT) switches that operate in sequence
    • T675A models available with adjustable differential
    • T675A and T678A have setpoint adjustment knob on front of case
    • Capillary tubing allows remote mounting of sensing element; models available with various lengths
    • T675A and T678A models available with a fast-response sensing element
    • Controller can be mounted in any position
    • Mounting accessories available for all applications
    • Ambient temperature compensated
