Электронный холодильный контроллер ERC112 со светодиодным дисплеем, специально разработанный для охладителей бутылок, коммерческих холодильников и морозильников. Он особенно подходит для ОЕМ клиентов, так как время, простая и надежная установка и высокое качество важны наряду с гибкостью. Дисплей может быть красным или синим. Контроллер доступен с верхней левой кнопкой «ECO» или «Оттайка». Нижняя левая кнопка может быть «Свет», «Отключение» или «Ускоренное охлаждение».
Документация
Контроллер может настраиваться тремя способами: используя «Программу», при помощи док-станции или вручную посредством кнопок на фронтальной панели. «Программа», лицензированная Данфосс, предлагает простую настройку параметров посредством USB шлюза. Программа поставляется отдельно; для получения технической литературы и дополнительной информации контактируйте с местным представительством Данфосс.

Control temperature sensor
The control sensor must always be connected and is used for controlling the cut-in and cut-out of
the compressor according to the set-point. The sensor is also used for the displayed temperature.
Most common placement is in the return air to the evaporator.
Evaporator sensor
The evaporator sensor is only used for de-icing of the evaporator and has no control purpose.
Place the sensor where the ice melts last.
Please be aware of that sharp fins can damage the cable.
Condenser temperature sensor
The condenser sensor is used to protect the compressor against high pressure when the
condenser is blocked or the condenser fan fails.
Place the sensor at the liquid side of the condenser. Use a metal bracket or metal tape to ensure
good thermal conductivity. Be sure that the cable does not pass hot spots at the compressor or
condenser that exceeds 80 °C.
