Meiling BCD - 191 type refrigerator circuit diagram when the switch is closed

When winter comes, as the ambient temperature decreases, in order to prevent the compressor from not starting for a long time, the switch can be moved to the winter state,
that is, the switch is closed. At this time, according to the different cooling temperatures of the refrigerator, the winter compensation heater will participate in the operation of the refrigerator as shown in the figure.
When the temperature in the refrigerator is higher than the preset temperature of the temperature controller, even if the switch is closed, the winter compensation heater still does not work, and
the compressor operates in cooling mode under the supervision of the temperature controller.
