Wireless Door Switch (FS-DOORSWITCH)


The Founten Door Switch is a battery operated remote wireless device designed to detect the opening and closing of doors or windows. By simply pairing the wireless door switch to a Founten thermostat, it will turn “OFF” that thermostat’s HVAC unit when it has detected that the door or window has been opened. A 2-wire terminal is built in, allowing for a customer supplied reed switch and magnet to be attached.  An optional internal magnetic sensor is integrated in its housing. This can be used to detect a magnet attached to the movable section of the window or door. For proper operation the magnet must stop within ½” of the internal sensor. The door switch is powered by 2 AA batteries and lasts for at least 12 months. Your Founten Site Manager will notify you when the battery has less than 20% of it’s capacity. You will also be able to see when a door or window is open on your Founten Site Manager. The door switch can be disabled via the Site Manager.
