Program Mode. For further information, refer to “Using Program Mode” on page 6. The Radome ECU is a Cool Only system (it does not have a reversing valve), therefore you must make sure the Cool Only Mode value “1” is set for parameter P-1 (this is the factory default for Radome ECU systems). DO NOT program Automatic Mode for a Cool Only unit. -

P-1: Operating Mode For Radome ECU select “1” for Cool Mode only. If your particular system has the electric heater option installed and heating is desired, set this parameter to “2” for Heat Mode only, or to “0” for Automatic Mode. See “P-15: Reverse-Cycle or Electric Heat”... - Page 10 P-15: Reverse-Cycle or Electric Heat Most Radome ECU systems do not support Heat Mode operation, so this parameter setting should remain at the factory default setting of “nor”. If your particular system has the electric heater option installed, then this parameter should be set to “ELE” for Electric Heater Installed.
