Floor Control Unit S High and Low temperature
Pre-assembled unit for regulation (fixed point or electronic climate control) and distribution, for mixed systems with two temperature levels (high+low), with stainless steel manifolds.
Floor Control Unit S High and Low Temperature with flow rate meters and electronic circulator is the ideal solution for mixed systems (radiant panels + radiators/fancoils) both thermo-autonomous and centralised: in this case, the advantages of the centralised system are perfectly combined with the convenience of a climatic thermoregulation system managed independently in each user.
The mixing system allows for precise balancing of the low-temperature system in compliance with the project data, either with a thermostatic head for fixed point regulation (heating only) or with an electric servomotor for climatic regulation (heating and/or cooling), reacting to any variation in flow rate or heat emission, keeping the temperature of the fluid in the radiant panel system constant.
The units, once installed in metal boxes only 11 cm deep, only require the hydraulic connection to the heat generator and electrical connections, drastically reducing installation time and errors.
