What is the difference between Basic and Precision modes?
In the Basic mode, the humidifier will turn on only with a call for heat. If there is a need for dehumidifica-
tion, this will occur only with a call for cooling.
In the Precision mode, if the conditioned space requires humidification, the system will circulate air and
turn on the humidifier to add moisture to the air regardless of whether there is a call for heat. If the condi-
tioned space requires dehumidification, the air conditioner will turn on to reduce the humidity level to the
desired setpoint regardless of whether there is a call for cooling.
During dehumidification, it is possible to over-cool the conditioned space by up to 2°F to achieve desired
humidity levels.
If the HUMIDITROL accessory is enabled in the Installer Settings, the Precision mode selection will
appear as HUMIDITROL. This selection allows for the most effective use of the HUMIDITROL equipment.
