(c) The temperature table is switched approximately once every 60 seconds. This prevents the blower fan from
turning on and off at the 3-minute restart for the coloured section in the table above (51 to 59%).
(d) When the room temperature is 29˚C or more (temperature rising) or 27˚C or more (temperature decreasing),
the circulator operates when the humidity is below 50%.
(e) When the humidity rises above 60% during circulator operation, dehumidifying begins again when the
dehumidifi er is set to operate at 50%, and circulator operations begin once humidity drops below 50%.
