However the priority is given to forced fan OFF
control
1) The thermostat is forcedly off by outdoor suction
temperature (TA).
• COOL: At TA < 66 ˚F [ 19 ˚C ]
• HEAT: At TA > 59 ˚F [ 15 ˚C ] or TA < 23 ˚F [ – 5 ˚C ]
2) The thermostat is forcedly off by outdoor suction
temperature (TA) and remote control setting
temperature (TS).
• COOL: At TA < TS + 5.4 ˚F [ + 3 ˚C ]
• HEAT: At TA > TS – 5.4 ˚F [ – 3 ˚C ]
1) The thermostat is forcedly off by outdoor suction
temperature (TA).
• COOL/FAN: At TA < 41 ˚F [ 5 ˚C ]
• HEAT: At TA < 23 ˚F [ – 5 ˚C ]
2) After fan-OFF status continued for 60 minutes, turn
on the fan for 1 minute.
The forced fan-OFF status continues or released by
outdoor suction temperature (TA) in this time.
<Release conditions>
• COOL/FAN: At TA ≥ 41 ˚F [ 5 ˚C ]
• HEAT: At TA ≥ 23 ˚F [ – 5 ˚C ]
