2.1 HEATING MODE
CONTROL
RANGE
35°C
85°C
Temperature readout can be viewed from screen 4
second long, each time heating button is
manipulated.
Pump is powered 7 seconds after the 3-way
valve, with a view at avoiding surge in system.
Request for Heating
3-Way Valve
powered
Pump powered
The request for heating can be initiated by :
- a room thermostat ,
- a room sensor,
- a programmer or
- an Expert Control
The character appears in this moment on the
screen.
The temperature read by the sensor on the
primary start can be viewed on the screen.
Sanitary mode is the rest position for the 3-way
valve.
When a heating request is active, the motor
driving the 3-way valve is energized for shifting
to heating mode.
The stem of the valve is then in « retracted »
position.
Extractor powered
Before activating the extractor, a check of
pressure switch status is carried out (contact
shall be in open position, otherwise default code
symbol
6 07
is displayed on the screen).
The extractor is power-supplied (model FF only).
Page 13

Training manual :PIGMA Gal Evo
Burner ignition
Flame detection
Ignitor and gas valve
powered
When pressure switch contact is set to closure, the
gas valve and the igniters are power supplied.
A permanent check of flow rate is developed with the
aid of 2 primary sensors (Forward & Return).
Flow rate Control
Gas valve is fed by the ignition power (adjustable by
parameter 2 20).
Flame detection is obtained by the ionization
electrode. In the event that the ionization sensor does
not sense any current during the ignition phase (8
seconds maximum), the boiler turns into safety state
and code symbol 5 01 is displayed on the screen.
Model FF only: a functional test of extractor is
performed by use of air pressure switch. If no signal is
detected after 20 seconds, the boiler turns to stand-by,
and code symbol
6 P1
is displayed on the screen.
Testing air pressure
switch
Flame detection enables the gas valve and the
extractor to carry out modulation of flame intensity
according to heat request.
Heating system output is adjustable by parameter 2
31 in operating ranges
Minimum output can be controlled directly by acting
on the gas valve.
Burner flame turn-off will take place at the following
T° values:
In the 1st min after flame detection:
T°off = set point T° + 8°C
In the 2nd min after flame detection
T°off = T° set point T° + 6°C
After the 3rd min after flame detection:
T°off = set point T° + 4°C
This logic of operation allows to avoid possible
occurrence of delayed ignitions and extinctions by
Modulation of burner
flame
Overheat Control
Overheat control is provided through a thermostat
(102±4°C) located at the outlet of the primary heat
exchanger. Resetting to be effected manually from the
control panel.
Default 1 01 is shown on screen. Reset possible when
temperature reads 87°C.
Notice. Primary start sensor (NTC1) is to control that primary temperature may not exceed set value
88°C; in this occurrence, the sensor interdicts the burner to start ignition.
If flow circulation in the heating sytem is not sufficient to fulfill the purpose, an automatic by-pass valve
can open (maximum capacity = 350 l/h).

2.1.1 Assembly view of system in heating mode
Notice.
The primary start sensor (NTC1) checks to ensure that the primary circuit heat level
may never exceed 88°C in temperature; in this state, the sensor interdicts the burner
to start flame ignition.
When the circulation flow in the heating system is not enough to comply with the need ,
an autonatic by-pass valve can open ( maximum flow rate 350 l/h).

Wilo INTMTSL 15/6.7 HE-2: ( 32 kW).
The P.C.B. controls modulation of the circulation pump at two different speeds V2 (55w) and V3 (80w).
On “sanitary” the pump always works on V.3 to allow excellent heat exchange
On “heating” the circulating device has 2 speeds that are operated by the heating del-ret ΔT control.
Operated as follows:
ΔTdel-ret < ΔT – 2°C → V2;
ΔTdel-ret > ΔT → V3;
where: ΔT= 20°C (default value, which can be set by parameter 2 39 between 10 and 30°C).
Speed switching is performed with a 5 minute delay (value that cannot be set) up or down.
It is possible to exclude the pump modulation with the parameter 2 38:
- 0: speed 2 fix;
- 1: speed 3 fix;
- 2: modulating.

4.7 BY-PASS VALVE
The boiler is equipped with an automartic by-pass valve allowing protection from the occurrence of a poor
flow rate from the system, which may be originated for instance from some closures of the thermostatic
cocks.
This DP is governed by a valve and a spring which open more or less for an extent depending on applied
load.
The by-pass valve ensures, in the main heat exchanger, a minimum flow rate of 50l/h. It is mounted
behind the main valve with 3 bar rating.
4.8 PRIMARY HEAT EXCHANGER
Primary heat exchanger is made from cupper metal. It is coated with an aluminum and silicone base paint
with high temperature resistant property.
The function of this exchanger consists in transfering heat from products of combustion to water flowing in
the heating circuit lines or in the sanitary heat exchanger.
The exchanger is rack-mounted in the upper part of the combustion chamber. It is held in positiin by two
screws secured to the side panels in the chamber.
4.9 PRESSURE PICK-UPS (FF ONLY)
Pressure pick-ups are to verify in real time the pressure
availabe in the primary circuit.
Contact closed > 0,6 b
Contact open < 0,4 b

4.11 HEATING EXPANSION VESSEL
Expansion vessel consists of two distinct parts assembled, made from metal sheet 1,8 mm thick. Inside, the
tank is separated through a SBR rubber membrane (see, pictures shown below).
The expansion vessel is located in the frame behind the boilere. Inflating pressure is 1 bar. Maximum
capacity of the system is about 175 litres.
A valve allows the u technician to make a yearly check of inflating pressure in the expansion vessel.
4.12 SANITARY FLOW RATE
When set to sanitary mode, because water flow rate is higher than 1,6 litres minute, the turbine fitted inside
the sanitary flow meter transfers through a « reed » relay the command to the electronic PCB to initiate the
ignition sequence.
A sanitary filtre is embodied in the flow meter with a view at protecting the turbine and the sanitray
exchanger from penetration of impurities. To prevent any delayed start up caused by surge arising in the
cold water pipe network, a time control can be organised through parameter 2 52 within 0.5 sec and 20 sec
( 0.5 sec by default). With the aid of parameter 8 25 and key INFO it is possible to have a reading of sanitary
water flow rate.
Operation check data of turbine by measuring voltage on CN14 of the electronic PCB is :
- 0Vdc = no flow rate
- 5Vdc = no flow rate
- between 2Vdc and 3Vdc = flow rate

5 GAS LINE
5.1 GAS VALVE TYPE SIT SIGMA 845
The gas valve installed in the boiler is type SIT 845 SIGMA embodying 2 solenoid safety valves supplied
from a 230 Vac source and a pressure modulation valve, 24 Vdc, for control of flow to the burner.
Flow modulation management is obtained through the electronic PCB, by an output data reading from the 3
temperature sensors.
This sort of gas valve can operate both with natural gas and liquid gas as well. In case gas quality needs be
changed , it is simply necessary that also injectors in the gas storage tank be changed. Highest allowable
pressure to the valve is 60 mb.
An igniter typeNAC504 is secured to the gas valve body.
This gas valve allows to control :
► maximum power to burner
► minimum power to burner

5.5 FLUE EXHAUST PORTS (SUCTION TYPE MODEL)
On the boiler top there is installewd an outlet socket (60/100) for connection with suction type exhaust pipes .
Two pressure ports allow measuring quality of combustion during the COMBUSTION ANLYSIS mode as well
as 2 pressure taps are provided for pressure switch tests.
5.6. AIR PRESSURE SWITCH (SUCTION CAP TYPE DESIGN)
The boiler is fitted with an air pressure switch to check the vacuum state in suction caps and the extractor
for regular functioning.
25kW: Off = 50Pa/0,50 mbar
On = 60Pa/0,60 mbar
30kW: Off = 74Pa/0,74 mbar
On = 89Pa/0,89 mbar
The pressure tap (-) of the pressure switch is jointed to the pressure tap in the extractor.
The pressure tap (+) is measured directly in the casing of the air pressure switch.
A measurement of Dp is taken during every sequence of ignition. If the read value is correct, the burner can
ignite a flame.
In thepresence of any trouble, faults of 2 types are likely to be found:
6 07 : pressure switch contact closed while extractor is not powered yet.
6 P1 : pressure switch contact remains open while extractor is being energized.
For preventing condensation risks from occuring in the pressure switch tube, a regenerator for
condensate is fitted in the tube.

5.7.1.POST-VENTILATION
Different cycles of post ventilation according to the cases
of figures:
during a setting to safety 5 01 : 40 seconds
during a setting to safety linked to water circulation 1 03, 1 04, 1 05, 1 06 or 1 07 : 20 seconds
during a fault in water flow circulation 1 P1, 1 P2 or 1 P3 : 10 seconds
►Post-ventilation after a heating request:
parameter 2 43= 0 5 seconds ( at each burner firing stop)
parameter 2 43= 1 3 minutes ( at each burner firing stop)
►Post-ventilation after a sanitary request:
parameter 2 54= 0 T°Dép<75°C = No post-ventilation; start T°>75°C = 3 min
parameter 2 54= 1 fix 3 min (at each burner flame out).

5.6.1 SPOTT UNIT ( MODEL CF)
The SPOTT unit is to control the flue stack for a good thermal draught. This valve is located in the antibackflow device.
This is a sort of thermal contact that opens when temperature is 75±3°C Its opening causes the burner to
flame out, and it brings the boiler to stop; code symbol 6 01 is displayed on screen. Reset takes place
automatically 12 minutes after flame out.
5.7 FLUE EXHAUST / MODEL CF
The boiler is equipped with an anti-return
device measuring 130 mm in diameter in
its upper part and 125 mm in lower part.
Installatiom of the flue stack must be in
compliance with the regulations in force in
the country concerned.

8 ERROR CODES
8.1 BOILER PROTECTION SYSTEMS.
There are two types of errors for malfunctions:
- Shutdown (solved by resetting);
- Safety stop (No Reset: the boiler will start working again properly when the cause is removed).
There is a third type of error code that is used to indicate a malfunction that does not stop the boiler which
continues to work properly (Indication).
8.1.1 Error codes
The error codes are divided in six different functional units, in other words the first figure indicates which
functional unit of the boiler is involved in the error:
