8.D.9 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/heater 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/heater 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.
NOTE: An external demand applied to the Lead boiler in a cascaded system will be treated as a local or stand alone heat
demand and not trigger the cascade heat demand.
•
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.
•
DemandO– 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.
