INSTALLATION INSTRUCTIONS62-0249-13T775R Series 2000 ElectronicStand-Alone ControllerPRODUCT DESCRIPTIONThe T775 electronic stand-alone controllers are the nextgeneration of commercial and agricultural controlscapable of remote sensing of temperature and providingswitched and/or proportional outputs to various types ofloads. A built-in time clock is standard.A Reset function is available for all T775R models wherethe Sensor B temperature (e.g. outside temperature) isused to provide reset control for the Sensor Atemperature (e.g. boiler). For example, as the outsidetemperature gets colder, the setpoint temperatureautomatically adjusts to save energy.Three T775R models have analog (modulating) outputsfor actuator and motor control.IMPORTANTThe T775R 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. T775R Controller Configurations.a All models include a digital input for use with the disable or setback option.b The modulating (analog) outputs are 4-20 mA, 0-10 Vdc, 2-10 Vdc, or Series 90 selectable.c Each floating output eliminates two SPDT relay outputs.d The T775R2043 can support a high/low modulating limit at Sensor B for temperature control at Sensor A.ControllerModela Description ReplacesSPDT RelayOutputsAnalog(Mod)OutputsbFloatingOutputs c SensorInputsNbr ofSensorsIncluded EnclosureT775R2001 Reset Option N/A 4 None 2 2 2 NEMA 1T775R2019 Reset Option N/A 4 2 None 2 2 NEMA 1T775R2027 Reset Option T775J1043T775J1050T775J10682 2 None 2 2 NEMA 1T775R2035 Reset Option T775J1001T775J10762 None 1 2 2 NEMA 1T775R2043 Reset Option T775J1019T775J1027T775J1035None 2 None 2 d 2 NEMA 1
