Viewing Room Temperature and Unit Operation Status: The LCD will dis-
play the actual room temperature during normal operation. If the display is
blank, replace the batteries. Further, a snowflake symbol will appear on the
display when there is a demand for cooling (unit should operate when this
symbol is illuminated).
/
Setting the temperature: Turn setting dial. The display will flash indicat-
ing the setpoint temperature selected. After a short period, the display stops
flashing and shows actual room temperature.

in the display when batteries require replacement. Batteries should be re-
placed within 15 days, after which the thermostat will turn off the unit. When

batteries every 18 months. Thermostat takes 2xAA/MN1500 Alkaline Batter-
ies. Ensure that unit is unplugged or that electric circuit to unit is turned off,
prior to replacing batteries.
