Конденсация на службе комфорта

Котлы Innovens MAC PRO подходят для любой конфигурации
Установка для одного котла или каскада котлов может быть:

на стене (до 7 котлов)
на полу в один ряд (до 7 котлов)
«спина к спине» (10 максимум; 5+5)

Таким образом, можно очень точно определить размеры установки мощностью до 1140 кВт (10 котлов MCA 115 в каскаде).
Система управления Diematic iSystem позволяет соединить до 10 котлов.

Удобный монтаж и простое сервисное обслуживание
Принимая во внимание компактные размеры и небольшой вес, котлы этой гаммы легко устанавливать и обслуживать.

Система управления по выбору
В зависимости от установки возможно выбрать одно из двух типов управления :
Управление INICONTROL
Для простых задач или при реконструкции с уже существующей системой управления : дисплей LCD используется для параметрирования котла.

Эффективная система управления DIEMATIC ISYSTEM
При полном управлении прямым и основными смесительными контурами система DIEMATIC ISYSTEM включает в себя интеллектуальный процессор оптимизирующий работу отопительной установки.
Встроенная панель управления имеет новую эргономику для более удобного и быстрого программирования благодаря замене нескольких кнопок управления на одну вращающуюся ручку.

Мощность: от 8 до 115 кВт
Одинаковые размеры для всех моделей (В x Ш x Г): 750 x 500 x 500 мм
Управление на выбор: HMI Ini Control или Diematic ISystem
Чистый вес : макс. 69 кг
