Heating plant thermal control units

The heating plant mixing and distribution units are designed for

heating and/or cooling systems of medium / large size, and are

intended for uses in which a room can be set aside for a heat-

ing plant.

Their characteristic is that they are made up of modules as-

sembled in various configurations, that can be adapted in each

case to the size and complexity of the system that has to be

controlled.

THIS makes it possible to feed fixed point heating systems rath-

er than air-conditioning or cooling systems, set up mixed zones

with different water temperatures, feed numerous manifolds for

radiant systems, rather than high temperature radiators to raise

temperatures in bathrooms, or lines dedicated to machinery for

air treatment, and to serve multi-user systems.

Finally, the use of Class A inverter circulators makes the best

performance possible in terms of energy saving.

Block

The configuration illustrated is particularly indicated when the

circuits in a system need to be separated hydraulically.

The hydraulic separator, which may or may not be fitted with a

main distribution manifold, depending on the number of zones

served, acts to separate the primary energy production circuit

(boiler or refrigerator side) from the secondary usage circuit

(heated / cooled zones).

In effect, the two circuits have different water flow rate needs,

and in this way interference between the various circulators is

avoided.

Various control units can be fitted on the main distribution mani-

fold: a simple shunt unit serving a (high temperature) radiator

system, or a mixing unit that serves a (low temperature) radiant

system.

The mixing unit can be fitted with a thermostatic actuator, for

fixed point operation, or a modulating actuator with its own elec-

tronic control unit, in order to mix the water on the basis of an

air-conditioning curve.
