• program times and setpoints for heating and cooling,
• override the program temperatures,
• display present setting,
• set system and fan operation,
• perform simple configuration.
NOTE: See Fig. 9 for keypad information.
Setting Temperature

Programming section for complete instructions on changing 
the setpoints.

in both heat and cool modes.
