Dehumidification
■ Application:
Similar to the simplified dehumidification option,
this option also maximizes latent capacity by using
a humidistat and thermostat . This option allows the
room thermostat to control sensible cooling, while the
independent humidistat controls room humidity levels
■ Items Required:
• Humidistat combined with a . . .
• Model GT = 3 stage thermostat
• Model GS = 2 stage thermostat
• Return air sensor
OR
• I/O Expansion Module Jumper Setting:
• JP5=Shorted
• JP6=Open
Note: This feature is not available if unit is controlled by
wall sensor
■ Unit Control Settings:
• I/O Expansion Module Jumper Settings:
• JP5=Shorted
• JP6=Open
■ Wiring:
• Thermostat/Sensor combination:
• Field supplied sensor
