 Auxiliary heater output
Indoor unit type
Compact cassette
Slim duct
Wall mounted
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 72 °F(22 °C)
• and room temperature (Tr) increase above 52 °F(12 °C), signal output is on.
• and room temperature (Tr) increase above 70 °F(21 °C), signal output is off.
• and room temperature (Tr) decrease below 66 °F(19 °C), signal output is on.
• and room temperature (Tr) decrease below 48 °F(10 °C), signal output is off.
Tr-Ts=-20 °F( -10 °C)
 Fan delay setting (JM3)
This is used to continue indoor unit fan operation for 1 minute after thermostat "Off" in heating
mode.
1 minute delay control set by cutting jumper wire on PCB.
