1. A call for humidity comes from the humidity control
provided with TrueSTEAM. The humidity control is
connected to TrueSTEAM, either with wires or by
wireless connection.
2. The heating element coil heats water in the tank to
the boiling point.
3. The resulting steam flows out of TrueSTEAM into
the hot air supply duct of your HVAC system. If
remote mounting is used, the steam flows through
an insulated steam hose from TrueSTEAM to your
supply duct.
4. Air flow from your furnace fan carries the moisture
throughout your home. Your furnace may or
may not be heating the air, depending on your
thermostat setting and TrueSTEAM configuration.
5. When humidity in your home reaches the setpoint,
the humidity call ends and TrueSTEAM stops
producing steam. The furnace fan may continue
to run until humidity in the duct is completely
distributed to your home.
6. Sensors monitor water level in the tank. The built-in
solenoid valve opens and closes to automatically
refill the tank, as needed. During long periods of
inactivity, the tank will drain completely to prevent
water stagnating. The tank will automatically refill
when there is demand for humidity.
