Remote Digital Display for the TriStar Family Controllers. The TS-RM-2 provides the same data display as the TS-M-2 and TS-M-2-600V, except that it ships with 30 meters of cable and a flat faceplate. These features enable convenient mounting away from the controller. The meter enables manual functions and controller diagnostics. These capabilities will increase your confidence that the system is working properly and will help you to improve system reliability, battery life, and system performance.
