product description

Introduction

The Mixed heating circuit modules II and III are hydraulic multi-temperature modules with one or two motorised 3-way mixing valves and
energy efficient modulating pumps. Up to three circuits can be managed, including one directly (no mixing valve). The multi-temperature
modules are designed to be installed hydraulically independent of the boiler.
The Mixed heating circuit modules II and III can operate in one of two regulation modes:
Scenario no. 1: the boiler is equipped with an ATAG zone connection. The boiler and the module communicate for optimal efficiency. The
module and heating can be configured directly on the boiler control panel.
Scenario no. 2: the boiler does not have an ATAG zone connection option. When a heating request is sent to the module, the signal is
transferred to the boiler by a volt free contact. A system interface (option) must then be used to configure the module and heating.
