Control of 3-WAY FLOW LOGIC
1. Main Operating Functions
1-1. Room Temperature Control
The thermostat is turned ON/OFF according to
▲
T as shown below.
* Intake shift temperature (enabled only during heating)
During heating, a difference in temperature occurs between the top and bottom of a room. This value is set in
consideration for the difference between the temperature detected by the body sensor and the temperature at the
bottom of the room.
<Value set for intake shift temperature at time of shipment>: 4°C
Note:
The shift temperature can be selected in the range of 0 – 10°C, by using the remote controller simplified
setting mode.
(1) After the thermostat turns ON, it will not turn OFF again as a result of
▲
T for 5 minutes.
(2) After the thermostat turns OFF, it will not turn ON again for 3 minutes. (It also will not turn ON for 3 minutes
after the power is switched ON.)
(3) The compressor turns OFF if the mode is changed cooling
→
heating (or heating
→
cooling) while the com-
pressor is ON.
(4) If “test run” mode is selected, the thermostat will not turn OFF as a result of
▲
T for 60 minutes. (The thermo-
stat is forced ON.)

T = Room temperature - Set temperature
When remote controller
sensor is used
Room temperature = Temperature detected by the remote controller sensor
When body sensor is used
Room temperature = Temperature detected by the body sensor - *Intake shift temperature
