Picking Up "Thermo-ON" Signal during Cooling
Operation (Only for RCD-FSG(E) and RPF(l)-FSG(E)
models)
This function is utilized to pick up the cooling "Thermo-ON"
signal of compressor running. Connect wires as shown
below. The required parts are indicated in Table 4. 3. The
contact of RYa is closed when "THERMOSTAT" is ON
during cooling operation mode.
NOTE:
"Thermo-ON" indicates that one of the micro-computer
control function "THERMOSTAT" is ON as a
thermostat.
