The tekmarNet®4 User Switch 480 is a simple 3 button switch that provides an easy way to override system temperatures. With the push of a button, one can put all thermostats and boiler controls into an "unoccupied" or "away" state and take advantage of saving energy when the building is not being used. The buttons on this product are also programmable, allowing the user to experience scenes within their system. The 480 has three demand inputs that can provide access to tekmarNet® 4 scenes or set point devices from a telephone switch, home automation, or security systems.
