In the example shown in Figure 5 the function associated with the output OUT1 is
“pump status” and L1 lights up when the pump is running and switches off when the
pump is stopped.

START
All the starting operations must be performed with the cover of the
EVOPLUS SMALL control panel perfectly closed and the expansion
module correctly installed as described in paragraph 4.1.
Start the system only when all the electrical and hydraulic
connections have been completed.
Once the system has been started it is possible to modify the operating modes to
adapt better to the plant requirements (see par.8).

ADDITIONAL FUNCTIONS
EVOPLUS SMALL circulators are able to recognise automatically the type of
expansion installed and, depending on the type, the user menu will make available
the functions that that expansion can support.
The basic module introduces the following additional functions:

MENUS
Listed below are the user menu pages introduced by the basic expansion module:
Page 5.0
Page 5.0 allows you to set the “auto” or
“economy” operating mode.
“Auto” mode disables the reading of the status
of digital input IN2 and in fact the system always
activates the set-point set by the user.
“Economy” mode enables the reading of the
status of digital input IN2. When input IN2 is
energised the system activates a percentage
reduction of the set-point set by the user (Page
6.0 of the EVOPLUS SMALL menu).
For the connection of the inputs see par. 5.1.1
Page 6.0
Page 6.0 is displayed if “economy” mode has
been chosen on page 5.0 and allows setting of
the percentage value of the set-point.
This reduction will be carried out if digital input
IN2 is energised.
Page 12.0
On page 12.0 you can set the operating mode
of the output relay:
1.
Indication of alarms present in the
system.
2.
Indication of pump status: pump
stopped/pump running.
