SYSTEM MODE BUTTON: This changes the current operating mode of the thermostat
SET BUTTON: This button lets you adjust the target set temperature in the ECO and STANDBY modes.
UP (+) and DOWN (–) BUTTONS: These buttons increase and decrease the target set temperatures, and are also
used to adjust system setup options while in the configuration menus.
OK/INFO BUTTON: This button is used to review current temperature settings and current data from the room/air
and floor/slab temperature sensors.
This is the normal operating mode for regular heating temperature control. To view the current COMFORT set
temperature, select COMFORT mode with the mode button and press either the UP or DOWN button one time. You
can adjust the set temperature by continuing to press either the UP or DOWN button to the desired target value. The
available room/air temperature setting values while in COMFORT mode are between 40°F (5°C) and 86°F (30°C)
degrees. Save the changes by pressing the OK/INFO button.
ECO mode uses a lower target set temperature to save energy while you are away, which you can adjust separately.
To view the current ECO set temperature, select ECO mode with the mode button, then press the SET button. You
can adjust the ECO mode set temperature by pressing UP or DOWN to the desired target value. Save the changes by
pressing the OK/INFO button.
NOTE: The available range of the ECO mode set temperature is linked to and based upon, the current COMFORT
mode target set temperature. The ECO mode set temperature can range from 2°F (1°C) degrees to 10°F (5°C)
degrees LESS than the current COMFORT mode target set temperature.
ECO MODE EXAMPLE: if the present COMFORT temperature is 75°F (24°C) degrees, the ECO set temperature can be
from 65°F (19°C) to 73°F (23°C) degrees.
This mode is intended to be used during times of vacancy or non-use, to prevent the floor/slab from getting close to
freezing temperatures. To view the current FREEZE PROTECT set temperature, select FREEZE PROTECT mode with
the mode button, then press the SET button. You can adjust the FREEZE PROTECT mode set temperature by
pressing UP or DOWN to the desired target value. The available setting values while in FREEZE PROTECT mode are
between 40°F (5°C) and 50°F (10°C) degrees. Save the changes by pressing the OK/INFO button.
This mode is used when you want to completely turn off the heating output signal. The thermostat does not protect
the system from freezing when placed into STANDBY mode.
