Selecting the System Mode

The thermostat 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 thermostat controller is off;
however, when the frost protection
(Frost pr parameter) is enabled, the thermostat
controller still calls for heat if the temperature falls
below 42°F/5.5°C.

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 T600HPN-4 and
T600HPN-4+PIR models.
Note: The setting for the Fan cont parameter may
affect the fan operation on a call for heating.
• Smart Fan Mode (smart): Energizes the fan all
the time for Occupied states, and only on a call for

Programming the Daily Schedule – Two-Event
(T600HPP-4 and T600HPP-4+PIR Models)
The schedule-setting menu is used to enter the
Occupied or Unoccupied states for each day of the
week. The schedule-setting menu reflects either a
two- or a four-event schedule per day, based on what
was selected in the 2/4event parameter during the
configuration process. If the schedule-setting menu
does not reflect a two-event schedule, select two
events in the 2/4event parameter of the Installer
Configuration Menu.
When changing the time, press and release the
UP/DOWN arrow keys to change the time in 1-minute
increments; press and hold down the keys to change
the time in 30-minute increments.
Note: Programming one of the digital inputs to remote
NSB disables the menu.
To set the time schedule for a two-event schedule,
follow the steps in Table 5. See Table 7, Events 1
and 2, for an example of a two-event office schedule.
