Therma-Stor Products Group DEH 3000R FOR INSTALLER & HOMEOWNER 3. Operation, Display, Setting

FOR INSTALLER & HOMEOWNER: 3. Operation

On the display screen, a solid “O” in front of any of the 3 functions (SETPOINT, VENT, FAN) indicates the function is operating. A flashing “O” indicates it is in a wait mode and not available at the moment. No “O” indicates the function is currently OFF.

Solid “O” before	Indicates
SETPOINT	Dehumidifier on
VENT	Fresh air ventilation cycle in progress
FAN	Fan on

Wait mode is a factory-programmed time period meant to prevent short cycles. This extends the life of the dehumidifier. When a flashing “O” is encountered, the unit is in wait mode and IT COULD BE UP TO 10 MINUTES BEFORE OPERATION

RESUMES.
