What happens if the mode is set to OFF?
The humidification and dehumidification are turned off. The thermostat will simply control to the
temperature setpoint.
What is the difference between Basic and Basic/DP
(same as Precision and Precision/DP)?
The DP stands for Dew Point. If the remote outdoor sensor (Part #46M98) is connected and Basic/DP or
Precision/DP is selected, the thermostat will automatically optimize the indoor humidity level based on the
desired indoor temperature and outdoor temperature. In Dew Point mode,the humidify control level
(described on the previous page) is ignored.
If Basic/DP or Precision/DP is chosen, a new menu DEW POINT ADJUSTMENT will be displayed.
What is the Dew Point Adjustment Function?
The Dew Point Adjustment can be set from -15% to +15%. These settings allow you to customize the
Dew Point setting for your home. Some homes may require an adjustment to help maintain comfort. If you
notice condensation on your windows, set the adjustment lower, between -15% to -5%. If your home feels
dry, set the adjustment upwards, between +5 to +15%.
Can I change the Humidifier Maintenance Service Intervals?
No. This interval is fixed based on the run time of your system and if the humidifier has been turned on.
When the recommended service interval has expired, the screen to the right will appear. Simply press
DELAY to be reminded later or RESET to reset the interval.
