8.D.8 External
The External Conguration Screen applies to the 0-10VDC (4-20mA) analog input BAS signal, and allows
adjustment of the following parameters:
To navigate to the External Conguration Screen, touch the External Icon on the Conguration Screen.
•
Control Mode – This parameter provides the ability to either disable external control or congure the unit for Boiler Set
Point or Firing Rate control mode.
•
Max Set Point – When the Control Mode is set to Boiler Set Point, this is the maximum value that corresponds to
the Demand Max value.
•
Min Set Point – When the Control Mode is set to Boiler Set Point, this is the minimum value that corresponds to
the Demand Min value.
•
Demand Max – This is the maximum value that corresponds to the control mode selected. With Firing Rate
control mode selected, this is the maximum rate at which the boiler will run. The unit of this parameter is %, so if
the value of this parameter is 10000, or 100.00%, this equates to 10.0VDC or 20mA.
•
Demand Min – This is the minimum value that corresponds to the control mode selected. With Firing Rate control
mode selected, this is
the minimum rate at which the boiler will run. The unit of this parameter is %, so if the value of
this parameter is 2000, or 20.00%, this equates to 2.0VDC or 4.8mA.
•
Demand On – This is the threshold (VDC/mA) at which the input signal will initiate the selected control mode behavior.
The unit of this parameter is %, so if the value of this parameter is 1500, or 15.00%, this equates to 1.5VDC or 4.6mA.
•
Demand O – This is the threshold (VDC/mA) at which the input signal will deactivate the selected control mode
behavior. The unit of this parameter is %, so if the value of this parameter is 1000, or 10.00%, this equates to 1.0VDC or
4.4mA.
•
Input Type – This parameter allows the user to select between voltage (0-10VDC) or current (4-20mA) input. Jumpers
will need to be congured accordingly.
