Heating Circulation Groups

The NOVAZONE DM mixing fixed-point multizone group guarantees the correct water flow-rate and a correct pumping head in all heating systems that require a higher performance

than the circulation pump, allowing to set a different supply temperature of heating zones and a different heat generator working temperature.

The combined hydraulic separator ensures that the heating zones are hydraulically independent from the generator.

There are three different versions, based on the number of zone to be covered by the module:

ART. 26130 NOVAZONE DM 130

Multizone heating group with 1 direct zone and 1 mixing fixed point zone

ART. 26113 NOVAZONE DM 113

Multizone heating group with 2 direct zones and 1 mixing fixed point zone

ART. 26133 NOVAZONE DM 133

Multizone heating group with 1 direct zone and 2 mixing fixed point zones

THE PRODUCT

The NOVAZONE multizone group guarantees the correct water flow-rate and a correct pumping head in all heating systems that require a higher performance than the circulation pump. With the mixed zone, it is also possible to manage and modify the supply temperature of the heating zones. The combined hydraulic separator ensures that the heating zones are hydraulically independent from the generator.

The direct multizone unit NOVAZONE DM does not modify the supply temperature of the heating zones, maintaining it equal to the heat generator working temperature.

The mixed zone (thermostatic or motorized) controls the supply temperature through a mixing motorized valve and its probe. The unit is composed by every hydraulic element necessary to the functioning of the single heating zones.

Each zone is equipped with pump Grundfos UPM3 Hybrid, ErP-Ready.

The pump is setted on the function «proportional pressure», but can easily be set on:

PWM: external control through PWM, A or C profile

PP: proportional pressure

CP: constant pressure

CC: constant curve

AA: AUTOADAPT

The single zone includes, besides of the pump, a supply and a return valve, a check valve and, in some equipments, analog thermometers. The check valve can be excluded if maintenance operations must be performed. Each valve is provided with a sensor probe that allows to check the temperature, both in the supply and in the return phase.

Other pumps are available on request.

Its shape enables easy installation and maintainability.

The unit can be wall- or flush installed.
