    What is a dry contact thermostat?
    Also known as a passive contact, dry contacts don't have power or voltage supplied directly from the switch. Instead, it comes from another source. These contacts act like a simple switch that can open or close the circuit without the need for an applied voltage to make that change happen.Aug 17, 2021

    What are dry contacts on a boiler?
    A dry contact, also called a voltage-free or potential-free contact, is a type of electrical switch that doesn't supply power itself. Instead, it relies on an external power source to energize the connected circuit.Jan 20, 2025

    What is the difference between dry contact and wet contact?
    Wet contacts are suitable when you want to control and power the lock directly through the same circuit. Dry contacts are used when you need to interface with external power control systems or when the lock falls outside the ACU's power specifications.
