The stages of capacity control forthese units are achieved by starting andstopping the RTRM is mounted in the controlpanel and is factory wired to the re-spective internal components. TheRTRM receives and interprets informa-tion from other unit modules, sensors,remote panels, and customer binarycontacts to satisfy the applicable re-quest for Control ActuatorReliaTel ControlThe ECA monitors the mixed air tem-perature, return air temperature, mini-mum position setpoint (local or remote),power exhaust setpoint, CO2 setpoint,CO2, and ambient dry bulb/enthalpysensor or comparative humidity (returnair humidity against ambient humidity)sensors, if selected, to control dampersto an accuracy of +/- 5% of stroke.
