1.4.9 Compensating the Temperature around People
(For units with the infrared floor sensor)
Change the ratio between the suction air temperature and floor temperature used to calculate
the temperature around people.
The temperature around people is calculated using the values of the suction air thermistor and
the infrared floor sensor. The factory setting is "Normal" (the average value of the suction air
temperature and the floor temperature is applied). However, the rate at which the suction air
thermistor and the infrared floor sensor affect the temperature around people can be changed
with this setting.
To reflect the effect of the temperature around the ceiling, select the "Priorities given on the
suction air temperature" (the Second code No.
02
).
To reflect the effect of the temperature around the floor, select the "Priorities given on the
floor temperature" (the Second code No.
04
).
The infrared floor sensor can be disabled by selecting "Suction air temperature only" (the
Second code No.
01
).
