Setpoint Adjustments
This section details control setpoints that can be modified
from factory defaults and how to modify those setpoints.
Unit Setpoints
Table 13. Unit setpoints that can be modified in the TD-7
Setpoint Name Description Factory Default
Condenser Purge Time
(on units with condenser valves only)
The amount of time (in minutes) that the compressor will open its condenser valve during
purge mode when the unit is not operating.
20 minutes
Discharge Air Cooling Setpoint BAS
Used as the cooling setpoint on fixed setpoint units and on units that reset their discharge air
temperature setpoint as the low value in the reset equation. This value should be set to the
desired temperature needed for startup.
55°F
Discharge Air Cooling Setpoint
Max BAS (reset DAT units only)
Sets the upper limit in the Reset Equation in Cooling Mode. This value can be adjusted to the
desired maximum setpoint the discharge air should reach during cooling mode.
65°F
Discharge Air Heating
Setpoint BAS (Units with Heat Only)
Used as the heating setpoint when the unit is in heating mode. This value should be set to
the desired temperature needed for startup.
90°F
Discharge Air
Low Temperature Cutout
Value that triggers a diagnostic when the discharge air temperature is below this value for 10
minutes. This value can be adjusted to the desired low air temperature, which triggers the
diagnostic.
35°F
Duct Static Pressure
Setpoint BAS
The duct static pressure setpoint is set by the analog value named duct static pressure
setpoint BAS. This value should be set to the desired pressure needed for startup.
1 in (H
2
O)
Duct Static Pressure Safety Lockout
Shuts down the unit if the duct static exceeds this setpoint. It should be set to the desired
pressure needed for startup.
2 in (H
2
O)
Dirty Air Filter DP
Generates a diagnostic for a dirty air filter when the differential pressure exceeds the
setpoint.
10 in (H
2
O)
Occupied Offset
(DAT Reset Units Only)
Determines the occupied cooling and heating setpoints when the unit resets the discharge
air temperature off either return or space temperature.
2°F
Occupied Standby Offset
(DAT Reset Units Only)
Determines the occupied cooling and heating setpoints when the unit resets the discharge
air temperature off either return or space temperature and is the occupied standby mode.
4°F
Space Temperature Setpoint BAS
(DAT Reset by Space Temp Air Units Only)
Sets the space setpoint when the unit is selected to do discharge air reset based off the
space temperature. This value is used to determine the occupied heating and cooling
temperatures which reset the discharge air temperature setpoint.
72°F
