Pro-Dialog Plus 30RB – это система управления одноконтурными, двухконтурными или трехконтурными жидкостными чиллерами с воздушным охлаждением 30RВ или тепловыми насосами воздух-вода 30RQ. Система Pro-Dialog Plus управляет пуском компрессоров, что необходимо для поддержания нужной температуры воды на входе и выходе теплообменника. В режиме охлаждения система управляет работой вентиляторов для поддержания требуемого давления конденсации в каждом контуре.

Документация

 В режиме охлаждения система управляет работой вентиляторов для поддержания требуемого давления конденсации в каждом контуре. В тепловых насосах система регулирует и оптимизирует циклы размораживания каждого контура с целью минимизации уменьшения теплопроизводительности. Система Pro-Dialog Plus осуществляет постоянный мониторинг предохранительных устройств для обеспечения их надежной работы. Система Pro-Dialog Plus  также обеспечивает доступ к программе Quick Test (быстрое тестирование), контролирующей все входы и выходы.

 Все системы Pro-Dialog Plus могут работать в трех независимых режимах:
— Режим местного управления: управление машиной осуществляется командами с интерфейса пользователя.
— Режим дистанционного управления: управление машиной осуществляется удаленными контактами (контактами без напряжения).
— Режим CCN: управление машиной осуществляется командами из сети Carrier Comfort Network (CCN). В этом случае используется кабель передачи данных для соединения агрегата с коммуникационной шиной CCN.  

 Выбор режима работы осуществляется кнопкой Start/Stop(пуск/остановка). В случае автономной работы системы PRO-DIALOG Plus (в режиме местного или дистанционного управления) она сохраняет все свои возможности управления, но при этом не предусмотрено использование каких-либо возможностей сети CCN.

Электропитание всех плат осуществляется от общей шины 24 В переменного тока с заземленным нулем.
Предупреждение: При подключении плат к системе электропитания обеспечивайте правильную полярность, поскольку неправильное подключение приводит к повреждению платы.
В случае перерыва в подаче электропитания автоматически осуществляется повторный пуск агрегата без внешней команды. Но если в момент прекращения подачи электропитания имели место какие-либо ошибки, то они сохраняются  и в некоторых случаях могут воспрепятствовать повторному пуску контура или агрегата. Все платы непрерывно осуществляют контроль и индикацию работы своих электронных схем. При нормальной работе на каждой плате светится светодиод.
— На плате NRCP-BASE красный светодиод мерцает с интервалом 2 секунды, что свидетельствует о нормальной работе платы. Другая периодичность мерцания светодиода указывает на наличие неисправности платы или программного обеспечения.
— Непрерывное мерцание зеленого светодиода на всех платах свидетельствует о наличии правильной связи платы по своей внутренней шине. Отсутствие мерцания светодиода указывает на наличие неисправности в электромонтаже шины  LEN.
— Оранжевый светодиод ведущей платы мерцает в течение сеанса связи через шину CCN.

 Датчики давления
Для измерения давлений нагнетания и всасывания в каждомконтуре используются электронные датчики двух типов.

 Термисторы
Датчики температуры воды испарителя установлены навходе и выходе. Датчик температуры наружного воздуха установлен под блоком управления. Для регулирования работы комплекса «ведомый/ведущий» (в случае необходимости регулирования выходящей воды) может быть
установлен дополнительный датчик температуры в системе циркуляции воды.
