Signal is output from connector when indoor fan and compressor turn on under heating operation.
*Signal output performance specifications are as shown as follows:
Example: When Set Temperature (Ts) is 22 °C
• and room temperature (Tr) increase above 12 °C, signal output is on.
• and room temperature (Tr) increase above 21 °C, signal output is off.
• and room temperature (Tr) decrease below 19 °C, signal output is on.
• and room temperature (Tr) decrease below 10 °C, signal output is off.
