Heat/Cool Indicator Display
Setpoint display: when the system is set for only Heat or only Cool, there is no flame ( ) or snowflake
( ) icon under the setpoint value.
When the system is set to AUTO ( ), the following applies:
• When the thermistor used for H/C control is above the Cool Setpoint, the Cool Setpoint will show on
the display along with the snowflake ( ) under the setpoint.
• When the thermistor used for H/C control is below the Heat Setpoint, the Heat Setpoint will show on
the display along with the flame (
) under the setpoint.
• When the thermistor used for H/C control is between the Cool and Heat Setpoints (inclusive), the last
active system setpoint (Cool or Heat) will show on the display.
When the system is set to AUTO ( ), the blink rates for the snowflake ( ) and flame ( ) under
the setpoint are as follows:
• When no Cool or Heat cycle is running and no compressor protection timer running, if the Heat
Setpoint is showing, then the flame (
) under the setpoint will blink at 4.5 seconds ON and 1.75
seconds OFF.
• When no Cool or Heat cycle is running and no compressor protection timer running, if the Cool Setpoint
is showing, then the snowflake ( ) under the setpoint will blink at 4.5 seconds ON and 1.75 seconds
OFF.
• When Cool cycle is running, then the snowflake ( ) under setpoint should be solid.
• When Heat cycle is running, then the flame ( ) under setpoint should be solid.
• When the compressor timer is running before Cool cycle, then the snowflake ( ) under setpoint
should blink 1.5 seconds ON and 0.5 second OFF.
• When the compressor timer is running before Heat cycle, then the flame ( ) under setpoint should
blink 1.5 seconds ON and 0.5 second OFF.
