Mixing system thermoregulator for automatic control of heating and
cooling functions of small and medium systems with radiant panels (floor
and ceiling) or with high temperature (radiators, fancoils), such as
houses, apartments, shops, offices, etc. Option of managing a
centralised system.
This regulator manages the different functions required for the
climatic control of the mixing system, such as controlling a mixing
valve and relative pump.
Features
One of the main features is the different management of the delivery
temperature according to the selected mode:
- 'Fixed point' mode: fixed delivery temperature in both heating and
cooling mode;
- 'Modulating' mode: fixed delivery temperature in cooling mode and
variable delivery temperature in heating mode.
In the latter case, the delivery temperature is modified compared to the
temperature set according to the system return temperature.
- 'Climatic' mode: the delivery temperature is calculated according to
the outdoor temperature (winter and summer climatic curve).
The regulator also manages the pump of the system and can control a
mixing valve with floating servomotor 3-point or modulating servomotor
0-10 Vdc.
Important
Install a dew sensor for every delivery manifold in systems that also
run in cooling mode. Every delivery manifold must be positioned in an
area adjacent to the room to be cooled, in order to have equal
temperature and humidity conditions. Moreover, the room must have a
suitable air handling system (e.g. a dehumidifier regulated by a
humidistat to control room humidity).
