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 differ-
ence 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
1) The judgment of selecting COOL/HEAT is carried out as
shown below. When +1.5 exceeds against Tsh 10 minutes
and after thermo.-OFF, heating operation (Thermo. OFF)
exchanges to cooling operation. Description in the
parentheses shows an example of cooling ON/OFF.
When –1.5 lowers against Tsc 10 minutes and after thermo. OFF, cooling operation
(Thermo. OFF) exchanges to heating operation.
2) For the automatic capacity control after judgment of cooling/heating, see Item 4.
3) For temperature correction of room temp. control in automatic heating, see Item 3.
