Pump group for underfloor heating to control constant temperature.
It is equipped with an actuator with a servo motor.
The task of the mixer group is to feed the low-temperature heating circuits directly from
the distributor outlets and to change the temperature of the medium at the inlet.
This is possible with the help of the mixer valve controlled by a thermostatic head.
With the help of two thermometers, the current temperature in the flow and return can be checked.
A return valve is provided in the return line to prevent automatic circulation of the medium
when the circulation pump is switched off. The constant value controller set is also supplied including
safety thermostatic switch (response temperature 55°C) to protect the system.
The mixer group can be supplied with a high-efficiency pump:
- Grundfos UPM3 HYBRID 25/70
- Wilo PARA 25/7
- Wilo UPM3 25/9
and thus comply with ErP 2009/12/EU, the European Community directive on energy saving.
