Shut down damage due to excess condensate.
Help protect your customers' HVAC equipment and their homes with the L2 WiFi Water Sensor and Switch.
An integral part of a whole home water damage protection system, the L2 WiFi Water Sensor and Switch helps protect against damage due to excess condensate produced by HVAC equipment.

Water damage can happen to anyone.
The L2 WiFi Water Sensor and Switch is an easy upgrade for any customer.
The L2 device can give customers added peace of mind and water damage protection from condensate overflow. The compact device can be wired directly to the furnace, air conditioner, dehumidifier, or other HVAC equipment. If water overflows the condensate pan or is sensed by the cable, the sensor and switch can turn the machine off or on and send an alert to the homeowner. The L2 device takes the guesswork out of locating the source of the condensate overflow and automatically stops it.

· Advanced leak awareness Alerts to condensate and overflow from HVAC and other 24 volt equipment with mobile device notifications. The device is equipped with LED lights and a 100 dBA alarm which also alerts the homeowner on-site.
· Quick setup This device is wired directly to HVAC and other 24 volt equipment and switches it on or off when excess condensate is detected via dry contacts.
· Versatile Can be wired to HVAC equipment with or without a condensate pan or pump, and can be installed vertically or horizontally. Works with any 24 volt equipment (air handler, boilers, heat pumps, furnace and more)
· Meaningful alerts The switch is triggered and customers are notified within seconds of detected excess condensate, taking the guess work out of identifying the source and location of the issue. Monitor temperature and humidity spikes outside of the user set range.
