PP1
LOW proportional head curve
PP2 AVERAGE proportional head curve
PP3
HIGH proportional head curve
Constant head
The circulation unit works at constant head, irrespective of the heat
request. The working point of the circulation unit will move along the
selected curve on the basis of the heat request.

AVERAGE constant head curve
CP3
HIGH constant head curve
Constant curve
The circulation unit works at constant speed, irrespective of the heat
request from the system. The working point of the circulation unit will
move along the selected curve on the basis of the heat request.

The parameters can only be set to different values by a qualified
technician and only if absolutely necessary.

The manufacturer declines all liability if parameter settings are
incorrect.
3.13 Alarm list
The following table shows the alarms of the
CONNECT LE
board which
are transmitted to the REC.
Alarm no. Description
47 External sensor open or in short circuit
48
External sensor open or in short circuit in system ther-
moregulation mode
49
No communication between the main micro and the periph-
eral micro
84 Mix delivery sensor MIX1, channel 2 in short circuit
85 Mix delivery sensor MIX1, channel 2 interrupted
86 Mix delivery sensor MIX2, channel 3 in short circuit
87 Mix delivery sensor MIX2, channel 3 interrupted
88 Incorrect combination between CHANNEL and ZONE
89 Reading/writing error in eeprom on main micro
If the CONNECT LE is connected to the boiler in Link mode , the CON-
NECT LE board will, in real time, monitor the presence of any alarm
signals (code B ) coming from the boiler board and will transmit
them to all the connected REC which will then display them. It is pos-
sible to reset the boiler alarms using the REC if the boiler board is
prearranged for this.
If the "sensor interrupted" alarm is signalled on the low temperature
zone, the corresponding circulation unit will be stopped and the mixing
valve will be completely closed for 120 seconds.
After this time, a post circulation will be activated for 120 seconds.
If the "sensor interrupted" alarm is restored, the adjustment cycle is
reactivated otherwise the zone will remain bocked until the operating
conditions are restored.
3.14 Checks after commissioning
Once commissioning has been completed, check:
-
the plumbing circuit for leaks
-
that the heating system is pressurised
- that the main switch for the system works
- that the electrical connections are correct.
For heat requests from a mixed system, check that the mixing valves
open and close correctly.
b
If even one of these checks provides a negative result, the sys-
tem is to be switched off and must not be started up again until
the fault has been eliminated.
