10.1.4 Regulation with Constant and Proportional Differential Pressure depending on the Water
Temperature
11.

CONTROL PANEL

The functions of EVOPLUS circulators can be modified by means of the control panel on the cover of the
electronic control device.
On the panel there are: a graphic display, 4 navigation keys and 3 LED warning lights (see Figure 9).

11.1 Graphic Display

Using the graphic display it will be possible to navigate in an easy and intuitive menu which will enable you to
check and modify the system operating mode, the enabling of the inputs and the working set-point. It will
also be possible to view the system status and the log of any alarms memorised by the system.
ENGLISH
In this regulating mode the regulating set point Hs is
reduced or increased according to the water
temperature. Tmax may be set from 0ºC to 100 ºC in
order to allow operation in both heating and
conditioning plants.
Regulation indicated for:
- Plants with variable flow (two-pipe heating
plants), where a further reduction of the
circulator performance is ensured depending
on the lowering of the temperature of the
circulating liquid, when the demand for heating
is lower.
Plants with constant flow (single-pipe and
-
underfloor heating plants), where the circulator
performance can be regulated only by
activating the temperature influence function.
