Input and Output Identification

All the inputs and outputs of the C1050 use pluggable screw type terminal blocks with elevator style clamping, which
make connections easier and more secure. Output functionality will vary depending on the number of compressors in
use (1 or 2 - see below).
The C1050 Heatpump Controller has 2 separate communication ports offering varying functionality based on whether
or it is a heatpump standalone controller (HPS) or not (HP).
