Modular Firstbox Low Temperature

Allows the creation of systems with high temperature zones low temperature zones (floor systems) assembling one or more modules together as needed. Besides the standard offer of pre¬assembled boxed modules, individual modules are also available which can be used to build the distribution system that is most suited to your needs. The distribution manifold can be fed from both left and right and the branches can be directed either upwards or downwards. The open manifold installed upstream from the zone distribution modules hydraulically separates the primary circuit from the secondary circuits. The non¬return valves on the individual modules prevent recirculation and eddy currents that keep the terminals hot and the supply circuits to the pump floor systems non¬functioning. To exclude the individual circuits with stopped pumps, there must be electrothermal heads or zone valves directly connected to the distribution manifolds. In modules with electronic climate regulation, the automatic management of the individual low temperature zone is done by the climate regulator that is controlled by the thermostat and acts directly on the mixing valve servomotor and excludes the zone circuit with the circulator not running. Through the use of electrical boxes for wiring the high and low tempera¬ture circulators (not included) controlled by zone thermostats, system operation can be automated.
