INSTALLATION INSTRUCTIONS62-0255-09T775U Series 2000 ElectronicStand-Alone ControllerPRODUCT DESCRIPTIONThe T775 electronic stand-alone controllers are the nextgeneration of universal controls capable of remotesensing of temperature, humidity, pressure, etc. andproviding switched and proportional outputs to varioustypes of loads. A built-in time clock is standard.The T775U controller allows a wide range of sensors tobe configured. Humidity, pressure, temperature, or any0-5 Vdc, 0-10 Vdc, or 4-20 mA input is supported.A Reset function is available where the Sensor Btemperature (e.g. outside temperature) is used to providereset control for Sensor A (e.g. humidity). For example,as the outside temperature gets colder, the setpoint canautomatically be adjusted to prevent condensation.IMPORTANTThe T775U is an operating control, not a limit orsafety control. If used in applications requiringsafety or limit controls, a separate safety or limitcontrol device is required.Table 1.
