TF : Temperature of
discharge air
Ts : Temperature set by
remote controller
Based on the difference between TF and Ts, and the amount of temperature
change, the operation capacity is determined by the Fresh air intake to
command the operating frequency to the outdoor unit.
1) COOL operation
TF(n)-Ts(n) : Temperature difference n : Times of detection
TF(n-1)-TF(n) : Temperature change amount
2) HEAT operation
Ts(n)-TF(n) : Temperature difference amount n : Times of
detection
TF(n)-TF(n-1) : Temperature change amount
The Thermostat OFF will be activated only when Forced Thermostat OFF
conditions are satisfi
ed.
Forced Thermo-
OFF
(TF type)
The Forced thermostat OFF will be activated when conditions below are satisfied.
(1) Outdoor / Suction air temp. (TA)
・ COOL ・・・ When TA ≦ 66°F (T α c)
・ HEAT ・・・ When TA ≧ 59°F (T α h) or when TA ≦ 14°F
(2) Outdoor / Suction air temp. (TA) and temperature set by remote controller (Ts)
・ COOL ・・・ When TA ≦ Ts + 37°F (T β c)
・ HEAT ・・・ When TA ≧ Ts − 37°F (T β h)
(3) Temperature of discharge air (TF)
・ COOL ・・・ When TF ≦ 37°F (T γ c)
・ HEAT ・・・ When TF ≧ 140°F (T γ h)
