This allows a single device to control levels in an above ground tank and underground well, and prevent either from running dry. A master-slave option allows up to seven controllers to be directly connected to each other. A new single-point controller includes a time-delay function to allow for filling or emptying of a tank with a single level point. All functions and adjustments of the CLD/P Series are made via rotary switches and potentiometers on the face of the unit. LEDs indicate power and relay output states. The UL, cRus and CSA approved controllers are in compact, 17.5mm or 35mm-wide housings, with DIN-rail mount or eleven pin plug connection.
