Constant curve
The circulation unit works at constant speed, irrespective of the
heat request from the system. The working point of the circula-
tion unit will move along the selected curve on the basis of the
heat request.

3.13 Alarm list

The following table shows the alarms of the BAG
are transmitted to the REC.
Alarm no.
47 External sensor open or in short circuit
External sensor open or in short circuit in system
48
thermoregulation mode
No communication between the main micro and
49
the peripheral 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 BAG 3 is connected to the boiler in Link mode, the BAG
board will, in real time, monitor the presence of any alarm sig-
nals (code r) coming from the boiler board and will transmit
them to all the connected REC which will then display them. It
is possible 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 temper-
ature 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 sec-
onds. If the "sensor interrupted" alarm is restored, the adjust-
ment 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.
9
If even one of these checks provides a negative result, the
system is to be switched off and must not be started up
again until the fault has been eliminated.
