Cooling will not come on. (cont.) • The thermostat has a built-in time delay on cooling. To prevent equipment damage, allow five to ten minutes after changing the setting before the air conditioner starts. • If temperature setting is lower than the current temperature, and the display shows COOL, set the system control to the OFF setting for ten minutes. After ten minutes, return the system control to the COOL setting. If the air conditioner comes on, the compressor may have reached its high limit temperature protection and shut down. If the air conditioner does not come on after ten minutes and the display shows COOL, contact your utility. The house is too warm or too cool. • Press Present Setting key to check the current temperature setting. • If desired, change the temperature setting. See Operating Your Thermostat section. 24 69-1153
