Thermo On/Off
ƒ Purpose
Maintain the custom indoor temperature.
ƒ Concept
Thermo is turned on or off through comparison between the indoor temperature and set temp
erature.
ƒ Control specifications in detail
ƒ Notes
- In case of cooling operation, if the indoor temperature is above the setting temperature, thermo becomes on and
if it is
below the setting temperature, thermo becomes off.
- In case of heating operation, occupants' comfort shall be optimized by operating
thermo on and off at the higher tem-
perature than the setting temperature considering that high temperature tends to go u
p.
- In case of a normal indoor unit, heating offset value of 2 K is applied and this can be adjusted with the option code.
Offset value shall not be a
pplied in case that users set up the room temperature using the cable remote control where
the temperature sensor is built in
