3.3 Functional description
The "Unibox T RTL vario" is intended for indi-
vidual room temperature control and for limiting
the return temperature in a surface temperature
balance.
The integrated thermostatic valve is equipped
with a presettable valve insert and thus enables
the flow rate to be accurately adapted to the
required heat demand (see chart in the appen-
dix) and hydraulic balancing to be carried out.
The installation position of the "Unibox T RTL
vario" should be chosen so that fluid flows first
through the heating circuit and then through
the "Unibox T RTL vario" valve. The heating
fluid cools down between the entry point of the
heating surface and the "Unibox T RTL vario".
The flow rate is controlled by the sensor ele-
ment located in the volume flow. The self-act-
ing thermostat controls the desired room
temperature. The temperature of the surface
temperature balance can be corrected by turn-
ing the handwheel of the return temperature
limiter (see 3.4.1 on page 30). The desired
room temperature can be set by turning the
handwheel of the self-acting thermostat.
3.4 Operating elements
3.4.1 Return temperature limiter
You can set the desired fluid temperature for
the surface temperature balance with the hand-
wheel. The return temperature limiter integrated
in the valve detects the fluid temperature flow-
