Room Temperature Detection Temperature Compensation During Heating - Mitsubishi SCM40ZS-S Technical Manual

(d) If the cooling/heating selection signal is given by the external input, the operation mode is transmitted to the remote
control.

(24) Room temperature detection temperature compensation during heating

With the standard specification, the compressor is turned ON/OFF with the thermostat setting temperature. When the thermostat
is likely to turn OFF earlier because the unit is installed at the ceiling where warm air tends to accumulate, the setting can be
changed with the wired remote control indoor unit function "
one of the setting temperature +3, +2 or +1°C in order to improve the feeling of heating. The setting temperature, however, has
the upper limit of 30°C.
(25) Return air temperature compensation
This is the function to compensate the deviation between the detection temperature by the return air temperature thermistor and
the measured temperature after installing the unit.
(a) It is adjustable in the unit of 0.5°C with the wired remote control indoor unit function "RETURN AIR TEMP".
• +1.0°C, +1.5°C, +2.0°C
(b) Compensated temperature is transmitted to the remote control and the compressor to control them.
Note (1) The detection temperature compensation is effective on the indoor unit thermistor only.
(26) High power operation (RC-EX1A only)
It operates at with the setting temperature fixed at 16°C for cooling, 30°C for heating and maximum indoor fan speed for 15
minutes maximum.
(27) Energy-saving operation (RC-EX1A only)
It operates with the setting temperature fixed at 28°C for cooling, 22°C for heating or 25°C for auto. (Maximum capacity is
restricted at 80%.)
(28) Warm-up control (RC-EX1A only)
Operation will be started 5 to 60 minutes before use according to the forecast made by the microcomputer which calculates
when the operation should be started in order to warm up the indoor temperature near the setting temperature at the setting time
of operation start.
