3.1Конструкция и функционирование

Регулятор используется для регулирования систем отопления с функцией приготовления горячей воды в зависимости от температуры наружного воздуха.

Регулятор может управлять следующими контурами установки:

–одним емкостным водонагревателем,

–макс. двумя модулирующими отопительными аппаратами без eBUS, одним модулирующим отопительным аппаратом с eBUS или в качестве альтернативы одним 2-ступенчатым котлом,

–двумя регулируемыми контурами и

–одним нерегулируемым контуром

Для расширения системы отопления от индивидуальной котельной можно подключить до шести дополнительных модулей (принадлежности) с двумя смесительными контурами каждый. То есть: регулятор может управлять максимум 15 контурами.

Для удобства управления первых 8 отопительных контуров можно подключить приборы дистанционного управления.

В зависимости от потребности каждый смесительный контур может переключаться между:

–отопительным контуром (радиаторный контур, контур теплого пола и т. п.),

–регулированием по постоянному значению,

–повышением температуры обратной линии,

–контуром горячей воды (дополнительно к интегрированному контуру горячей воды).

С помощью модулирующего коммутационного модуля (принадлежность) можно подключать несколько модулирующих отопительных аппаратов Vaillant либо 1- и

2-ступенчатые теплогенераторы.

Максимальное количество подключаемых отопительных аппаратов/теплогенераторов зависит от встроенного коммутационного модуля.

Таб. 3.1 Максимальное количество подключаемых отопительных аппаратов/теплогенераторов

Благодаря подключению дистанционного телефонного контакта (вход контакта с нулевым потенциалом) посредством телефонного дистанционного переключателя teleSWITCH можно переключать режим работы регулятора с любого места по телефону.

В базовом оснащении регулятор поставляется одним комплектом. Этот комплект включает в себя:

Количество Деталь

Регулятор calorMATIC 630 с корпусом для настенного монтажа

4Стандартный датчик VR 10

1Датчик температуры наружного воздуха VRC DCF или VRC 693 в зависимости от страны (→ таб. 1.1)

Таб. 3.2 Объем поставки комплекта calorMATIC 630

Вбазовом оснащении регулятор может управлять:

–одним емкостным водонагревателем,

–макс. двумя модулирующими отопительными аппаратами без eBUS,

одним модулирующим отопительным аппаратом с eBUS или в качестве альтернативы одним 2-ступенчатым котлом,

–двумя регулируемыми контурами и

–одним нерегулируемым контуром

.

Если необходимо дополнить систему отопления, например, дополнительными отопительными контурами, то в систему отопления в целом можно интегрировать дополнительные компоненты (→ рис. 3.1).

четного значения температуры помещения на различное время дня

На рис. 3.2 Вы видите фрагмент временной программы. На горизонтальной оси указано время дня, на вертикальной — расчетная температура помещения. Диаграмма показывает такой ход программы:

1До 06:00 для помещений действует температура 15 °C

(пониженная).

2В 06:00 начинается первое временное окно:

с этого момента действует расчетная температура помещения 21 °C.

3Первое временное окно заканчивается в 09:00:

с этого момента действует расчетная температура помещения 15 °C.

4Далее следуют еще два временных окна с температурой 21 °C.

Как временные окна влияют на регулирование отопления, простыми словами можно объяснить так:

Если Вы эксплуатируете систему отопления в режиме Авто, регулятор активирует настроенные временные окна, в которые Ваша система отопления нагревает включенные помещения до установленной температуры (→ расчетная температура помещения). Вне этих временных окон система отопления регулируется таким образом, что включенные помещения охлаждаются до установленной температуры (→ пониженная температура). Когда пониженная температура достигнута, регулятор обеспечивает, чтобы она поддерживалась системой отопления до запуска следующего временного окна. Таким образом предотвращается дальнейшее охлаждение квартиры.

iПроконсультируйтесь с Вашим специалистом относительно оптимальной настройки отопительной кривой, поскольку на регулирование отопления влияют также измеренная температура наружного воздуха и настроенная отопительная кривая.

Описание аппарата 3

Функция защиты от замерзания

Регулятор оснащен функцией защиты от замерзания (в зависимости от температуры наружного воздуха). В режимах Выкл и Экон (кроме временных окон) эта функция обеспечивает защиту системы отопления от замерзания.

Если установлен режим Экон, и функция защиты от замерзания (в зависимости от температуры наружного воздуха) неактивирована, отопительный контур переключается на понижение.

Если температура наружного воздуха опускается ниже +3 °C, то для каждого отопительного контура автоматически задается настроенная пониженная температура (Ночь).

iЕсли датчик температуры наружного воздуха Вашей системы отопления не может принять DCF-сигнал, то после включения регулятора время и дату следует настроить вручную.

>Следите за тем, чтобы время и дата были настроены правильно, чтобы установленные временные программы и программа «Отпуск» работали корректно и можно было контролировать следующий срок выполнения технического обслуживания.

>Попросите включить регулятор, чтобы Вы в любой момент могли узнать статус системы отопления и быстро обратить внимание на сбой.

>Используйте программу «Отпуск» (→ гл. 5.5), чтобы сэкономить расходы на энергию во время Вашего отсутствия.
