Entering Humidity Setpoints
You can enter setpoints for humidification and
dehumidification after configuring the temperature
setpoints. A fixed 5% RH deadband is present between
the humidification and dehumidification to prevent
overlap in these humidity setpoints. For example, if the
humidification setpoint is 50% RH and the
dehumidification setpoint is changed from 70% RH to
45% RH, the humidification setpoint is automatically
changed to 40% RH by the controller.
To enter humidity setpoints, follow the steps in Table 5.
Selecting the System Mode
The controller has four system modes:
•
Automatic Mode (auto):
Automatic changeover
between heating and cooling. This is the default
setting.
•
Cooling Mode (cool):
Cooling operation only.
•
Heating Mode (heat):
Heating operation only.
•
Off Mode (off):
The controller is off; however,
when the frost protection (
Frost pr
parameter) is
enabled, the controller still calls for heat if the
temperature falls below 42°F/5.5°C.
To set the system mode, follow the steps in Table 6:
Selecting the Fan Mode
The controller has three fan mode settings:
•
On Fan Mode (on):
Energizes the fan all the time
for both Occupied and Unoccupied states, even if
the system mode is set to off.
•
Automatic Fan Mode (auto):
Energizes the fan
only on a call for heating or cooling, for both
Occupied and Unoccupied states. This is the
default setting for the T606MSN-4 and
T606MSN-4+PIR models.
Note:
The setting for the
Fan cont
parameter may
affect the fan operation on a call for heating.
