Fig. 27 - SERVICE INFO MENU
SERVICE -- FURNACE STATUS OR GAS PAC STATUS
The Status screens will show all of the current operating
parameters of each installed piece of equipment.
HEAT STAGE:
• OFF, LOW. HIGH
Displays stage of heat that the furnace is currently delivering.
AIRFLOW CFM:
• (furnace model dependent)
Cubic Feet per Minute of air the blower is currently delivering.
LEAVING AIR TEMP:
This sensor is NOT required. However, if LAT sensor is
connected to the Damper Control Module, the sensor will read
leaving air temperature of the furnace.
INDOOR COIL TEMP:
This sensor is NOT required. However, if HPT sensor is
connected to the Damper Control Module, the sensor will read
temperature at that location (i.e. if placed in return-air, will read
return-air temperature).
INDUCER RPM (90% FURNACES ONLY):
• Inducer motor RPM value.
BLOWER RPM:
• Blower motor RPM value.
STATIC PRESS:
• Inches of water. Displays static pressure that the furnace
is currently experiencing.
LOCKOUT TIMER:
• Seconds
If a lockout timer is active, this will show the current time value.
See furnace manual for details on lockout timers.
SERVICE -- FAN (,'OIL STATUS
ELECTRIC HEAT:
• OFF, LOW, MED, HIGH
Displays stages of electric heat that the fan coil is currently
delivering.
AIRFLOW CFM:
• (fan coil model number dependent)
Cubic Feet per Minute of air the blower is currently delivering.
LEAVING AIR TEMP:
This sensor is NOT required. However, if LAT sensor is
connected to the Damper Control Module, the sensor will read
leaving air temperature of the fan coil.
INDOOR COIL TEMP:
This sensor is NOT required. However, if HPT sensor is
connected to the Damper Control Module. the sensor will read
temperature at that location (i.e. if placed down stream from
evaporator coil, and before electric heat, will read coil leaving air
temperature).
BLOWER RPM:
• Blower motor RPM value
STATIC; PRESS:
• Inches of water
Displays static pressure that the fan coil is currently experiencing.
SERVICE -- HEAT PUMP / AC STATUS
STAGE: (HEAT / COOL):
• OFF. LOW, HIGH
Displays stage of heating or cooling that the Heat Pump/AC is
delivering.
DEFROST:
• NO, YES
Displays status of defrost mode if heat pump.
AIRFLOW CFM:
• Indoor unit CFM measurement.
LEAVING AIR TEMP:
This sensor is NOT required. However, if LAT sensor is
connected to the Damper Control Module. sensor will read
leaving air temperature of the indoor unit.
OUTDOOR COIL TEMP:
• Degrees F.
Temperature of the outdoor unit coil (only available on 2-stage
communicating outdoor units).
BLOWER RPM:
• RPM feedback from indoor motor.
STATIC; PRESS:
• Static pressure of indoor unit.
