PUMP ANTI-LOCK FUNCTION

The hydronic module has a function that starts
up the pump at least once every 24 hours for 30
seconds in order to reduce the risk of the pump
locking up due to prolonged inactivity.
3.7

3-WAY ANTI-LOCK FUNCTION

Both in "DHW" and in "DHW-system central
heating" mode, the hydronic module has a func-
tion that activates the motorised 3-way unit 24
hours after the last time it operated by running
a complete cycle in order to reduce the risk of
the 3-way locking up due to prolonged inactivity.
3.8 RADIATOR ANTIFREEZE
FUNCTION.
If the system return water is below 4°C, the
hydronic module starts up until it reaches 42°C.
3.9

SOLAR FUNCTION.

If the solar inlet is active, any accumulated DHW
is heated to 50°C.
3.10 OUTDOOR UNIT DISABLE
FUNCTION.
With the inlet active, outdoor unit operation is
inhibited.
3.11 DIVERTER VALVE MANAGEMENT
(SUMMER / WINTER).
The unit electronics has a 230V outlet to manage
the summer / winter diverter valves. The switch
occurs when the mode (summer / winter) is
changed from the control panel or from the
CAR .

3.12 ANTI-LEGIONALLA FUNCTION.

With the integrated DHW resistance, the func-
tion can be activated using the CAR
See the instructions booklet to configure the
function.

3.13 AUTOMATIC VENT FUNCTION.

In the case of new central heating systems and
in particular mode for floor systems, it is very
important that dearation is performed correctly.
The function consists of the cyclic activation of
the pump (100 s ON, 20 s OFF) and the 3-way
valve (120 s D.H.W., 120 s C.H.).
The function is activated in two different ways:
- each time the hydronic module is re-powered;
- by pressing the buttons at the same time (3
and 5 Fig. 2-1) for 5 seconds with the hydronic
module in stand-by.
N.B.: if the hydronic module is connected to
the CAR , the "stand-by" function can only be
V2
enabled from the remote control panel.
In the first case, the function has a duration of
8 minutes and it can be interrupted by pressing
the "reset" button (2). In the second case, it has
a duration of 18 hours and it can be interrupted
simply by switching the hydronic module on.
Activation of the function is signalled by the
countdown shown on the indicator (14).
3.14 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
The following checks and maintenance should
be performed at least once a year.
- Visually check for water leaks or oxidation
from/on connections.
- After discharging system pressure and bringing
it to zero (read on the hydronic module pres-
sure gauge), make sure the expansion vessel
pressure is at 1.0 bar.
- Check that the system static pressure (with
system cold and after refilling the system by
means of the filling cock) is between 1 and 1.2
bar.
- Visually check that the safety and control
devices have not been tampered with and/or
short-circuited.
- Check the condition and integrity of the elec-
trical system and in particular:
- supply voltage cables must be inside the
fairleads;
- there must be no traces of blackening or
burning.
- Check ignition and operation.
- Check the operation of the appliance control
and adjustment devices and in particular:
- system regulation probes intervention;
IMPORTANT NOTE: in addition to yearly
maintenance, you must also check the heating
system and energy efficiency, with the frequency
and procedures that comply with the technical
regulations in force.
