Presentation
The MGm II basic and MGm III basic modules are hydraulic multi-temperature modules with one or two motorised 3-way mixing valves, ena-
bling the temperature of the controlled circuit to be modulated, and energy effi cient 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 MGm II can operate in one of two regulation modes:
Scenario no. 1: the boiler is equipped with a BUS BridgeNet® connection. The boiler and the module communicate for optimised operation.
The module and heating can be confi gured directly on the boiler control panel. They can also be confi gured using an system interface (option)
connected to the BUS BridgeNet®.
Scenario no. 2: the boiler does not have a BUS BridgeNet® connection option. When a heating request is sent to the module, the signal is
transferred to the boiler by a dry contact. An system interface (option) must then be used to confi gure the module and heating.
