Temperature control

The thermostat can be set to respond to its
internal temperature sensor, or to an option-
al remote indoor sensor. If multiple sensors
are used, the thermostat will respond to an
average of temperatures detected at each
sensor.
Humidification control
If optional remote indoor sensors are
installed, you can choose which sensor you
want to use for humidification control. You
can use a different sensor for dehumidifica-
tion.
Dehumidification control
If optional remote indoor sensors are
installed, you can choose which sensor
you want to use for dehumidification con-
trol. For example, you can use one sensor
for humidification control, and another for
dehumidification.
