2. Press the Unit Setpoints button.
3. On the Setpoint report, locate the point in the menu.
Use the arrows to scroll through the report if needed.
PKG-SVX027D-EN
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.
Used as the heating setpoint when the unit is in heating mode. This value should be set to
the desired temperature needed for startup.
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.
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.
Shuts down the unit if the duct static exceeds this setpoint. It should be set to the desired
pressure needed for startup.
Generates a diagnostic for a dirty air filter when the differential pressure exceeds the
setpoint.
Determines the occupied cooling and heating setpoints when the unit resets the discharge
air temperature off either return or space temperature.
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.
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.
Sets the return setpoint when the unit is selected to do discharge air reset based off the
return temperature. This value is used to determine the occupied heating and cooling
temperatures which reset the discharge air temperature setpoint.
The temperature that the condenser entering water must be below the return air temperature
before it will enable the economizer.
Time that the controller will sample the water temperature for and compare it against the
return air temperature to determine if the economizer can be enabled.
