3. Compressor Overcurrent Protection
4. Indoor Coil Freeze Protection
If the current draw of the compressor at start-up is greater
than the values in the chart below for approximately 3 seconds,
the compressor will stop and a code will be indicated at the
outdoor unit. After 3 minutes the compressor will restart.
If the overcurrent condition occurs 3 times in 20 minutes,
the system will lock out.It will be necessary to remove power
to the system to reset the lock outcondition.
Tpg_indoor: indoor unit pipe sensor temperature
When Tpg_indoor < Tpg1, the frequency of the compressor
decreases at the rate of 1HZ / 1 second.
When Tpg_indoor < Tpg2, the frequency of the compressor
decreases at the rate of 10HZ / 10 seconds.
When Tpg3 < Tpg_indoor <Tpg4, the frequency of the compressor
increases at the rate of 1HZ / 10 seconds.
outdoor unit will stop and indicate an underload malfunction
code at the outdoor unit. The compressor stops for a minimum
of 3 minutes. When Tpg_indoor >Tpg4, the compressor
will restart.
The coil sensor protects the coil from becoming too cold during
low cooling load days or periods of high humidity.
