Here is the reason for that problem per the manufaturers web-site
The low-pressure switch senses the refrigerant pressure in the sealed refrigeration system to
protect against certain conditions that could be detrimental to compressor life. The switch shuts
the unit down in the event of loss of refrigerant, fan motor failure, evaporator freeze-up and
airflow blockage. The switch automatically resets when the pressure rises to normal operating
pressures. The display will show "LP" if this switch is tripped.
The low-pressure switch will shut the heat pump down when the evaporator starts to freeze.
When the unit starts to freeze the low-pressure switch will be tripped, causing the display to read
"LP" This will prevent the evaporator from becoming damaged or deformed.
If the air outside the heat pump is not warm enough to produce heat, the system will shut down.
The actual point at which your unit will shut down due to low temperature varies depending on
which model you purchased, current weather conditions, and the amount of sunlight reaching the
heat pump. The shutdown can occur anywhere within a wide range of temperatures, usually 45°F-
55°F. This is not a "fixed" range. We stress that climate conditions, sunlight, and various models
respond quite differently to low ambient temperature. A shutdown occurs because low
temperatures will activate the systems low-pressure safeguard switch (digital thermostats will
display a code "LP".) The unit will start up again when the temperature has raised enough to reset
this switch. Note: Low ambient temperature does not necessarily affect the Chiller models
or the cooling cycle of the heat/cool units.
