2) Heating fan control
Q
The outdoor fan is controlled by TE sensor, TO sensor and the operation frequency.
(From Min. W1 to Max. are controlled according to the following table.)
(From Min. W1 to Max. are controlled according to the following table.)
R
During 3 minutes after start-up, the fan is fixed
with the maximum fan tap corresponding to
zone in the following table. After then the fan is
controlled by temperature of TE sensor.

If status, TE > 24°C continues for 5 minutes, the
operation stops. This status is same to the
usual Thermo-OFF which has no alarm display,
and the fan restarts after 2 minutes and 30
seconds. This intermittent operation is not
abnormal.

(The operation frequency differs according to the model type. The case of SM1102 is shown in the table below.)
5. Coil heating control
1) This control function heats the compressor by turning on the stopped compressor instead of a case
heater. It purposes to prevent slackness of the refrigerant inside of the compressor.
2) As usual, turn on power of the compressor for the specified time before a test run after installation,
otherwise a trouble of the compressor may be caused. As same as a test run, it is recommended to turn
on power of the compressor beforehand when starting operation after power of the compressor has been
interrupted for a long time.
on power of the compressor beforehand when starting operation after power of the compressor has been
interrupted for a long time.
3) A judgment for electricity is performed by TD and TO sensors. If TO sensor is defective, a backup control
is automatically performed by TE sensor. For a case of defective TO sensor, judge it with the outdoor LED
display.
display.
4) Coil heating is controlled by TD and TE sensor.
5) For every model, the power is turned off when TD is 30°C or more.
