Parameter P7 continued....

Allows manual control of the fan speed for system 

setup and commissioning tests.  Exiting this 

parameter returns the controller to normal operation.
When entering this parameter, the value shall be 

OFF (normal operation). Press the UP button to set 

the parameter value to On and then press the ENT 

button. The unit is now in manual control.
The major display shall read 50 for 50% output (5 

VDC out). The minor display shall show %SPD.
Pressing the UP button shall increase the displayed 

value and proportionally change the fan speed. 

Pressing the DN button shall decrease the displayed 

value and proportionally change the fan speed.
Allowed values are 0% and 20 to 100%, for 0 VDC 

and 2 to 10 VDC fan motor control voltage.
The fan speed will remain at the displayed value 

until the ENT button is pressed placing the unit back 

to the parameter selection mode.

Minimum Fan Speed, Parameter P8

Factory Default = 20%

Parameter P8 continued... 

%MIN #

 = 20% to 100% in 1% increments

Sets the min fan speed that the controller may 

control to. Note: the controller will not allow the 

output min to be set higher than the output max.

Maximum Fan Speed, Parameter P9

Factory Default = 100%

%MAX #

 = 20% to 100% in 1% increments

Sets the max fan speed that the controller may 

control to. Note: the controller will not allow the 

output max to be set lower than the output min.

An analog output across J15 terminals “REF” and 

“GND” for the measured temp or humidity.
