Program 9: Set DIP switches for direct freq. request with cascading (check box as applicable)
SW4-3 on outdoor unit set to ON
Yes No
Thi-A sensor replaced by 5 kΩ fixed resistor
Yes No
Cooling: Temperature setpoint set to 18 °C on wired remote control
Yes No
Heating: Temperature setpoint set to
30 °C
on wired remote control
Yes No
On wired remote control: Setpoint temperature button disabled
Yes No
Wired remote control disabled by signal to X2b-D3 Yes No
Program 10: Direct frequency request with the CompTrol Master
Analog signal
Activated
0-10 V
For setting the analog signal, see Set analog signal at analog input X3.
Description of direct frequency request with cascading: Adapts both Interface PCBs to the compressor frequencies of the outdoor
unit models installed on site as per Tables 1 and 2.
For FDC outdoor units: Set DIP switch S1 on Interface
1. Set DIP switch SW4-3 on outdoor unit PCBs of FDC outdoor units to ON (see Technical Manual of FDC series).
2. Identify which FDC outdoor units are installed on site (see Table 2).
3. Set DIP switches S1-5 to S1-8 in line with the FDC outdoor units installed on site (see Table 2).
4. On both Interface PCBs, use DIP switches S2-3 and S2-4 to set the signal ranges with or without signal overlap (see Table 1).
For SRC outdoor units: Set DIP switch S1 on Interface
Make sure there is always a request during a setpoint/actual value comparison.
1. Replace the Thi-A sensor with a 5 kΩ fixed resistor (see Technical Manual for heat exchanger connection module).
2. Set the temperature setpoint on the wired remote control:
─ When using to cool: Set temperature setpoint to 18 °C.
─ When using to heat: Set temperature setpoint to 30 °C.
3. Disable the wired remote control so temperature setpoint cannot be changed.
─ Alternatively: Disable the wired remote control by means of a signal to digital input X2b-D3 (Interface = Center).
4. Identify which SRC outdoor units are installed on site (see Table 2).
5. Set DIP switches S1-5 to S1-8 in line with the SRC outdoor units installed on site (see Table 2).
6. On both Interface PCBs, use DIP switches S2-3 and S2-4 to set the signal ranges with or without signal overlap (see Table 1).
