Points to Bear in Mind at the System Design
2.4.2 Main Considerations in Preparation of Control Circuit Diagrams
In addition to the design of the appropriate this system configuration it is also essential that the control
stsyem be made amply clear. If the system is designed and installed without a clear, comprehensive plan
then problems are inevitably going to occur during the test run.
Servicing too will become much more time consuming than necessary. However, if control circuit diagrams
are prepared along with the contract drawings in order to make the total system clearly visible then the
essential points relating to the electrical connections will be easily understood, the test run will go off
without a hitch and the whole system will be rendered fully effective.
Step 1: Compiling a
1. Mark each outdoor unit with a code.
System List
2. Add field settings and data for outdoor units, and outdoor unit No. if using sequential start.
(example using
3. Add the model number of each indoor unit connected to each refrigerant circuit.
Inverter K Series) 4. Assign each indoor unit a code.
5. Fill in the location of each indoor unit.
6. Group indoor units controlled by one or two remote controls. (group or individual control).
7. Assign central group Nos. if using centralized control.
8. Add field settings and optional equipment for indoor units.
9. Add unit No. if making separate field settings for each indoor unit under group control.
Note: With the R-407C PLUS Series, unit No. is determined through automatic addressing, therefore readout unit
Nos. after activating the power.
