Safety devices
The FAMILY CONDENS IS E boiler is equipped with the following
safety devices:
Safety valve that intervenes in the event of excessive hydraulic pres-
sure (max 3 bar).
Water circuit diagnosis which safeguards the boiler in the event of
insufficient circulation or lack of water. The electronics of the boiler,
by comparing the temperature read by the outlet and return sensors
(circulation analysis) and the rise rate of the output temperature (no
water analysis) ensures the safety lockout of the appliance.
Flue gas probe: this intervenes (putting the boiler in safety stop
mode) if the temperature of the combustion products exceeds the
maximum operating temperature of the discharge pipes.
Flue gas safety evacuation system incorporated in the pneumatic
operation of the gas valve subject to the premix burner The gas valve
is opened based on the quantity of air pushed by the fan.
This implies that, if the flue gases exhaust circuit
is blocked, the air flow is cancelled and the valve does not have the
ability to open.
Furthermore, the float present in the siphon prevents any passage of
the flue gases from the condensation discharge.
Condensate discharge obstruction safety device that via a con-
densate level sensor blocks the boiler if the level of condensate in the
heat exchanger exceeds the limit allowed
Over-temperature safety device on both the delivery and return
lines, with dual probe (limit temperature 95°C).
Fan safety that, through a Hall effect revolution counter, constantly
monitors the rotation speed of the fan.
The intervention of the safety devices indicates a boiler mal-
function, therefore immediately contact the Riello Technical
Assistance Service It is therefore possible to try and put the
boiler back in service after a short wait (see chapter on "First
commissioning").
The boiler must not be put in service, even temporarily, with
non-operating or tampered safety devices.
Replacement of safety devices must be performed by the Ri-
ello Technical Assistance Service, by exclusively using original
manufacturer components and referring to the spare parts list
accompanying the boiler. After carrying out the repair, perform
an ignition test.

Circulator setting
Circulator residual discharge head
The boilers is equipped with an already hydraulically and electrically
connected circulator, whose useful available performance is indicated
in the graph (fig. 1-2-3-4).
The circulator is factory set with discharge head of 6 meters.
The boiler is equipped with an anti-blocking system which starts
up an operation cycle after every 24 hours of stop, with the mode
selector in any position.
The "anti-locking" function is only activated when the boiler is
electrically powered.
It is strictly forbidden to operate the circulator without water.
Where there is the need to use a different curve, the desired level can
be selected on the circulator.
The main characteristics and how to set the desired operation are
described below.
User interface
The user interface is made up of a button (A), a two-coloured red /
green LED (B) and four yellow LEDs (C) arranged in a row (fig. 5).
The user interface allows to view the operating performance (oper-
ating status and alarm status) and set the operating mode of the
circulator.
The performance, indicated by LEDs (B) and (C) are always visible
during the normal operation of the circulator, while the settings are
made by pressing button (A).
Indication of the operating status
When the circulator is operating, LED (B) is green. The four yellow
LEDs (C) indicate the consumption of electric power (P1) as shown
in the following table

ed in the “Technical Data” table.
Indication of the alarm status
If the circulator has detected one or more alarms the bi-colour LED
(B) is red. The four yellow LEDs (C) indicate the type of alarm as
shown in the following table.

If there are multiple alarms, the circulator displays the highest
priority alarm only.
Display of the active settings
With the circulator powered, the active configuration of the circulator
can be viewed by briefly pressing the button (A). The LEDs indicate
the active settings.
No change to the configuration of the circulator can be made at this
stage. Two seconds after of pressing the button (A), the user inter-
face returns to the normal display of the operating status.
Key lock function
The key lock function is designed to prevent an accidental change of
settings or misuse of the circulator.
When the lock function is activated, the prolonged pressing of button
(A) is inhibited. This prevents the user from entering the setting sec-
tion of the circulator operating mode.
The enabling/disabling of the key lock function is made by pressing
button (A) for more than 10 seconds. During this step, all LEDs (C)
flashes for 1 second (fig. 6).
Variation of the operating mode
In normal operation the circulator operates with the factory setting or
the last setting made.
To vary the configuration:
- Make sure the key lock function is disabled.
- Press button (A) for more than 2 seconds until the LEDs start blink-
ing. Pressing button (A) briefly within a period of no more than 10
seconds, the user interface will display the next settings. The vari-
ous settings available will appear in a cyclic sequence.
- If the button (A) is not pressed, the last setting will be stored (fig. 7).
- Pressing button (A) allows to go back to the "display of the active
settings" and verify that LEDs (B) and (C) indicate, for 2 seconds,
the last setting made.
