描述

  • The T775 electronic stand-alone controllers are the next generation of universal controls capable of remote sensing of temperature, humidity, pressure, etc. and providing switched and proportional outputs to various types of loads. A built-in time clock is standard.
  • The T775U controller allows a wide range of sensors to be configured. Humidity, pressure, temperature, or any 0-5 Vdc, 0-10 Vdc, or 4-20 mA input is supported.
  • A Reset function is available where the Sensor B temperature (e.g. outside temperature) is used to provide reset control for Sensor A (e.g. humidity). For example, as the outside temperature gets colder, the setpoint can automatically be adjusted to prevent condensation.
