Function
The temperature regulating unit is designed to guarantee the
correct contribution of heating energy required by the user, by
measuring the outside and room temperature values to regulate the
correct system flow temperature for either heating or cooling.
It is supplied complete with:
4-way mixing valve, servomotor, pump, flow temperature sensor,
outside temperature sensor, system temperature return sensor,
cooling surface humidity control sensor, temperature controller, flow
and return thermometers, unions for connecting to the primary and
secondary circuits, with preformed shell insulation.
The unit is designed for connection for remote data transmission.
This unit solves the problems of installation of regulating
components in modern small and medium-sized systems, due to its
compact size and ease of use.
The unit is factory set for use with underfloor heating systems.
