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.
Analog Output Reference, Parameter P10
Factory Default = Temperature
REF H = Humidity, 0 to 10V for 0 to 100%RH
REF t = Temperature,
0 to 10V for 15° to 130°F (-10° to 55°C)
An analog output across J15 terminals “REF” and
“GND” for the measured temp or humidity.
