Damper Analog Output (HPC Plus Only)
The HPC Plus damper analog output terminals are listed under the label “Analog
Outputs” immediately to the right of the input connections (Figure 2).
Step
Procedure
1
Connect the damper actuator’s control signal (+) to the Heat
Pump Controller Plus at Terminal 11 (D).
§
This is a 0 to 10-Volt, 1 mA maximum connection.
2
Connect the damper actuator’s common or ground connection to
Terminal 14 (GND) of the HPC Plus.
Terminals 13 (F) and 14 (GND) are used for making a connection from a general
fault input (refer to the “Wiring the HPC or HPC Plus, Inputs, General Fault
Input [HPC Plus Only]” section of these instructions). Terminal 12 (E) is not
active.
