HEA T ANTICIP ATOR SETPOINT It is important that the anticipator setpoint be correct. T oo high a setting results in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint causes shorter “ON” cycles and may result in the lowering of the temperature within the conditioned space.

The defrost control shortens the defrost initiation time periods above 2°C (35°F) and extends the defrost initiation time periods below 2°C (35°F .
