S1A1 SP Upper Range—The control calculates the Upper Range by using S191 SP Setpoint and 

S192 SP Deadband, the results on lines show both values, in WC and Pa.
S1A2 SP Lower Range—The control calculates the Lower Range by using S191 SP Setpoint and 

S192 SP Deadband, the results on lines show both values, in WC and Pa.

S1A4 SP Control Override Sensor—Programs override static pressure control the room 

temperature gets too warm. Three selections are available: 

• None: Override capability is disabled
• Return: Allows the unit to monitor return air conditions. If the return air becomes warmer than 

the value set at SP Requested Speed up to, the evaporator fan speed will increase to help lower the 

air temperature.

• Remote: Allows the unit to monitor remote air conditions. If the remote temperature becomes 

warmer than the value set at SP Requested Speed up to, the evaporator fan speed will increase to 

help lower the air temperature.
In No Teamwork and Teamwork 2 applications, fan override control is based on selected sensor 

value. In Teamwork 1 and 3 applications, the master collects all sensor values for the selected 

override sensors in the group and builds a maximum or average value (based on S804 Teamwork 

is based on) and uses this temperature for the static pressure control override.

S1A5 SP Requested Speed up to—Sets temperature at which static pressure fan control will be 

overridden from the current fan speed. This parameter establishes the beginning point of the fan 

override control band.
S1A6 STD Speed at—Sets the temperature at which the fan will operate at 100% if room 

temperature continues to increase. This parameter establishes the end point of the fan override 

control band.
S1A7 Override Integration Time—Adjusts the fan speed of the unit based on time above SP 

Requested Speed up to so that accurate temperature control can be maintained. The SP Requested 

Speed up to and integration time work together to stabilize room temperature above SP Requested 

Speed up to. The smaller the integration time, the quicker the unit will react to temperature increase.
S1A8 Control Slew Rate Filter—Controls the rate of fan speed change while the override is active 

to avoid fan hunting. The filter value depends on the current control deviation from the setpoint. On 

the setpoint (at 0%), it’s typically set lower (slow), and at the end of the P-band (at 100%) it’s typically 

set higher (faster). The value is given in percent control output change per second. This parameter 

sets the rate of change based on where actual temp is when compared to setpoint.
S1A9 Current Override Temperature—Shows the current temperature of the selected override 

sensor. 
S1B1 Current Override Value—Shows the calculated fan override PI request.
