DIPS 3, 4, and 5 are used for humidifying.
DIP 3: Used to enable wireless operation.
• If DOWN (default), wireless terminal is disabled.
• If UP, wireless terminal is enabled.
DIP 4: Used to congure power monitoring.
• If DOWN (default), TrueSTEAM looks for R input
before allowing humidity.
• If UP, TrueSTEAM does not look for R Input before
allowing humidity. Power is still allowed to pass
through if R is wired. See “Make Power Monitoring
Decision” on page 28.
DIP 5: Used to congure back-up air
proving (optional).
• If DOWN (default), TrueSTEAM does not look for air
movement through an air proving device.
• If UP, TrueSTEAM looks for C connection before
allowing humidity. Wire an air proving device
between TrueSTEAM C and System C. See “Make
Add-On Air Proving Decision” on page 32.
Note: Setting DIP 5 up requires DIP 4 to be down. If
DIP 4 is up, DIP 5 position will not be used.
