    AI Overview
    Wired boiler heating thermostats provide stable, direct control of hydronic systems, using 2-wire or 3-wire setups (24V or line voltage) to signal boilers and zone valves. These thermostats maintain consistent room temperature by powering on/off, with options for non-programmable, programmable, and smart WiFi models that often require a C-wire.
