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 10).
9.1.
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.
9.2.
Navigation Buttons
4 buttons are provided for navigating in the menu: 3 buttons under the display and 1 at the
side. The buttons under the display are called active buttons and the one at the side is called
hidden button. Each page of the menu is made in such a way as to indicate the function
associated with the 3 active buttons (the ones under the display).
In this regulating mode the regulating set point Hs
is reduced or increased according to the water
temperature. THs 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.

Warning Lights
Yellow light: System live signal.
If lit, it means that the system is live.
Never remove the cover if the yellow light is lit.
Red light: Warning of an alarm/malfunction present in the system.
