STARTING
TURNING ON AND OFF
To turn the control unit on and off, press the ‘ esc ’ key for
at least 3 seconds. When the control unit is turned on it will
carry out a diagnosis of the internal circuitry to verify its
correct operation and the red led will flash three times.
If the control unit reveals no anomalies the red led will
remain on, otherwise it will continue to flash quickly and the
display will show the type of error.
BACKLIGHT
By pressing any key the backlight of the display is activated.
The backlight automatically shuts off after about 20 seconds
from the last key depressure.
ACOUSTIC SIGNALS
The control unit is supplied with an internal buzzer that gives
the user an acoustic feedback in case of pressure on the
keys, alarms and failure. The acoustic signal can be disabled
by properly setting the relevant ‘ Installer Parameter ’.
TEST FUNCTION FOR LOAD WIRINGS CHECK
By keeping pressed for 10 seconds the ‘

‘ button, the
control unit performs the functionality test of the loads
connected to it, in order to allow the installer to check
the wirings . The control unit checks the connected loads,
depending on the configured layout, by simultaneously
activating the relays outputs for about 30 seconds, while the
PWM outputs will be raised at the maximum speed.
The test activation is showed on the control unit by
activating the ‘ TEST ’ icon on the display.
To exit the Test mode, push the ‘ esc ‘ button at any time.
TEMPERATURE AND SPEED DISPLAY
The unit will normally show on the alphanumeric display the
temperature (in °C) measured by the sensors connected and
the speed (in %) of the collector pump controlled with the
PWM or 0..10V output.
The power on of the collector pump (Erp and/or Traditional) is
shown on the display with the icon ‘ ‘ as follows:
Icon ‘ ‘ still lit: Erp and/or Traditional
pumps OFF
Icon ‘ ‘ flashing slow: Erp Pumps ON and
Traditional OFF
Icon ‘ ‘ flashing fast: Erp Pumps and/or
Traditional ON
By pressing the keys ‘  ‘ or ‘  ‘ you can cycle through
the display of the value of the sensor or pump speed:
 S_1  S_2  S_3  %PWM  %010 
AUTOMATIC / ABC (Automatic Boiler Control)
OPERATION
The control unit can manage the installation selected in 2
different modes:
-
AUTOMATIC (Normal controller operation)
In this mode the control unit automatically manages and
controls the operation of the installation according to the
programmed data (normal controller operation).
- ABC (Automatic Boiler Control)
By pressing the ‘

‘ key you can enable or disable the ABC
function on the unit.
When the ‘ ABC ‘ function is active, the display will turn on
the ‘

‘ icon.
Following are the conditions which result in activating the
collector pump:
S_1≥TABC+Hysteresis value
and
S_1≥S_2+ Hysteresis value
Following are the conditions which result in turning off the
collector pump:
S_1<TABC
or
S_1<S_2
Where:
S_1 : Temperature measured by the collector sensor.
S_2 : Temperatura measured by the boiler sensor.er.
TABC
: Temperature set with installer parameter P2.
Hysteresis value for ABC function : 3.0°C (fixed -
unchangeable)
The only active controls will be those relative to the
maximum and safety temperatures.
RESET
In order to reset the device, press the key labelled as
‘
RESET ’ located behind the removable door; DO NOT USE
PINS OR NEEDLES .
