1) Based on the difference between Ta and Ts, the operation
frequency is instructed to the outdoor unit.
2) Cooling operation
Every 90 seconds, the room temperature difference
between temperature detected by Ta and Ts and the varied
room temperature value are calculated to obtain the
correction value of the frequency command and then the
present frequency command is corrected.
Ta (n) – Ts (n)
: Room temp. difference
n
: Counts of detection
Ta (n-1) – Ts (n) : Varied room temp. value
n – 1
: Counts of detection of 90 seconds before
3) Heating operation
Every 1 minute (60 sec.), the room temperature
difference between temperature detected by Ta and Ts
and the varied room temperature value are calculated to
obtain the correction value of the frequency command
and then the present frequency command is corrected.
Ts (n) – Ta (n)
: Room temp. difference
n
: Counts of detection
Ta (n) – Ta (n – 1) : Varied room temp. value
n – 1
: Counts of detection of 1 minute before
NOTE)
In case that Low volume is set, the maximum frequency is
restricted to approx. [SB].
