Model SS610E has been added to the line of patented Safe-T-Switch® electronic condensate overflow control switches. It is designed for use on mini-split systems. It includes reliable, low power-consuming, state-of-the-art microelectronics. The switches are designed for easy installation in both new and retrofit applications to protect home and commercial building owners from costly damage due to condensate overflow. The new easy-to-use SS610E switch sensor connects directly to the indoor unit wiring. Because the switch sensor uses power from the mini-split unit, no batteries are required. Its smaller sensor can easily fit into the confined internal spaces of most units. The sensor can be installed directly to the drain pan or clipped to the evaporator coil. The unit’s logic circuit continuously checks the probes for water and will shut down the system if water is detected. The onboard LED lights indicate the condition of the unit at a glance, removing any guesswork and will automatically reset once the water subsides. If necessary, the casing of the CPU unit can be mounted directly to the side of the unit. The SS610E has no moving parts to break and can be wired to the unit’s thermostat’s normally open or normally closed circuit.
