10.2 Expansion Modules

EVOPLUS SMALL circulators may be equipped with some expansion modules that allow their functions to
be increased.
For details on the procedures for installation, configuration and use of the expansion modules, see the
specific manual.

CONTROL PANEL

The functions of EVOPLUS SMALL 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 5).
ENGLISH
In this regulating mode the differential pressure is kept constant, irrespective of
the demand for water,
The Hs set point may be set from the display.
Regulation indicated for:
Heating and conditioning plants with low load losses
–
Two-pipe systems with thermostatic valves and head ≤ 2 m
–
– Single-pipe systems with thermostatic valves
– Plants with natural circulation
– Primary circuits with low load losses
– Domestic water recirculating systems with thermostatic valves on the
rising columns
In this regulating mode the circulator works on characteristic curves at a
constant speed. The operating curve is selected by setting the rotation speed
through a percentage factor. The value 100% indicates the maximum limit
curve. The actual rotation speed may depend on the power and differential
pressure limits of your circulator model.
The rotation speed may be set from the display.
Regulation indicated for heating and conditioning plants with constant flow.
