S120 CW Cap Filter at 0 - 100%— The CW Filter at 0% / 100% Controls the rate of change during a 

valve position adjustment to avoid overshoots. 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 % control output change 

per second.
S121 BMS Backup Temp Setpoint—Selects a temperature setpoint that will be activated in the 

event of a BMS time-out. The BMS timer must be configured for this parameter to activate. If the unit 

is operating in Coupled mode, located in Service Menus>Setpoint, S163, then this setpoint will affect 

the fan control setpoint. This temperature may affect fan speed if the control is setup to operate in 

Coupled mode during normal operation (see Table 4). This parameter is adjustable from 41-104°F 

(5-40°C). The default setting is 73°F (23°C).
S122 2nd Temperature Setpoint—Provides a way to program an alternate temperature setpoint 

that is activated by a dry contact through the customer inputs connections. When a customer input 

connection is set to “2nd Setpoint” and the input wired to that input is active, then the value set in 

this parameter sets the active temperature setpoint. This parameter is adjustable from 41°F to 81°F 

(5 to 27.2°C). The factory default is 41°F (5°C).
This temperature may affect fan speed if the control is setup to operate in a coupled mode during 

normal operation (see Table 4).

S124 Humidity Control Sensor—Determines which sensor is used to calculate the relative 

humidity. The humidity control type must be set to relative for the parameter to be active. The range 

is Remote or Return Sensor; the factory default is Return Sensor.
The right hand value allows choosing an alternate temperature control sensor for use during 

dehumidification. This sensor will replace the setting on line S102 while dehumidification is active. 

When the temperature control sensor (S102) is set to Remote, the default selection is Remote and the 

alternate selection is Return. When the temperature control sensor (S102) is set to Supply, the default 

selection is Supply and the alternate selection is Return.
S125 Humidity Setpoint—Selects a humidity that the cooling unit will maintain by removing or 

adding moisture to the air. The humidity setpoint will either be set in percent RH or as a Dew Point 

Value depending on what the humidity control type is set for. This parameter is adjustable from 20-

80%. The factory default is 50%.
