Introduction
The wireless valve head is used for controlling radiator
heating. An excellent replacement for the traditional
manual thermostatic valve head. For it to function properly,
pairing with a master controller is necessary. Up to 6 heads
can be paired with one controller within the same room.
Based on the data collected, the controller modulates
the opening of the head. The temperature measured by
the controller ensures even heating of the entire interior.
The head has an automatic calibration function. Using an
internet gateway, it is possible to control the set (head +
controller) using the ENGO Smart application.
Additional functions:
Open window function
(ventilating the room)
The head unit automatically closes the flow to the radiator
when a sudden drop in temperature is detected, indicating
that a window has been opened. After 15 minutes, the
system independently restores normal heating control.
Frost protection
When the ETRV head is closed, frost protection is
automatically activated. If the temperature sensor in the
head detects a temperature drop below 5C, the head
opens to supply heat to the radiator and prevent freezing.
