Fujitsu UTY-TTRXZ1 Fan Control Guide

To enable fan control on a Fujitsu unit using a thermostat, first identify the series compatibility:

• H-Series: ✅ Supports Fan Mode
• J-Series: ❌ No Fan Mode
• V-Series Heat Pump: ❌ No Fan Mode
• V-Series Heat Recovery: ✅ Supports Fan Mode

Fan Speed Control:

• Default fan speed follows DIP switch settings on the UTY-TTRXZ1.
• To override DIP settings, use separate fan speed commands (G1, G2, G3) if supported.
