Ending Temporary Temperature Setpoints

The temporary setpoints remain in effect for the
duration set in the TOccTime parameter or until
manually released.
Note: Setting TOccTime to 0.0 hrs prevents the
temporary setpoints from taking effect.
To manually release the temporary setpoint, while in
the Main User Menu:
1. Press the NO key to all prompts until the Temperat
set prompt appears. If the thermostat is in the
occupied state, this is the first prompt.
2. Press the YES key to cancel all temporary
setpoints.
3. Press the MENU key again and press the YES key
to exit the Main User Menu.
The setpoint reverts to the Permanent Temperature
Setpoint.

Selecting the System Mode

The thermostat 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 is off; however,
when frost protection (Frost pr parameter) is
enabled, the thermostat still calls for heat if the
temperature falls below 42°F/5.5°C.
To set the system mode while in the Main User Menu:
1. Press the NO key to all prompts until the system
mode prompt appears on the display. Press the
YES key to select the desired system mode.

Menu or press the NO key to return to the system
mode selection menu.

Selecting the Fan Mode

The thermostat 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 T600MSN-3 thermostats.
• Smart Fan Mode (smart): Energizes the fan all
the time for occupied states, and only on a call for
heating or cooling in unoccupied states. This is the
default setting for T600MSP-3 thermostats.

Menu or press the NO key to return to the fan
mode selection menu.
Programming the Daily Schedule – Two-Event
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 the UP/DOWN arrow
keys once 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.
