• Option 1 forces the fan on. This energizes system G when the HUM terminals energize from a humidity
demand
• Option 0 or 2 waits for the system to energize G before allowing HUM terminals to energize
• Because the thermostat is enforcing the fan, you do not need to power monitor or activate fan from
TrueSTEAM – the control does it for you.
• On TrueSTEAM, set DIP-4 up. Wire only HUM-HUM terminals of TrueSTEAM to HUM-HUM terminals of the
Equipment Interface Module of VisionPRO IAQ.
