7. Choose the number of cooling stages (1-4) or the type 

(PWM or Floating) from the Cooling list. 

8. Select the type of economizer from the Economizer list. 

a. If the heating, cooling, or economizer is configured 

as PWM, the Period, Zero Scale, and Full Scale 

settings must be configured.

b. If the heating, the cooling, or the economizer is 

configured as Floating, the Motor speed settings 

must be configured. 

9. Configure the Optional points. Refer to Table 16 on 

page 45 for possible values.

10. Click Commit to save the settings or Reset to revert to 

the last saved settings. 

11. Click Next to display the Input Configuration page. 

Table 16 lists the CVAHU Outputs for each controller model.

NOTE: The optional points Free1AO, Free2AO, 

Free1AORev, Free2AORev are available in the 

W7750C Model of CVAHU only. These enumerations 

must be selected to use terminals 6,7 and 8 of 

W7750C model. These outputs can be driven by 

XL15A or XL15C, but since Free1 and Free2 are 

digital in nature, XL15A and XL15C can only 

command these points to ON or OFF. Hence, these 

points can be driven only by digital outputs of Xl15A/

Xl15C loops.

Table 17 lists the CVAHU Outputs fields.
