Description
1Introduction
Standard electromechanical control panel for heating installations
without a control unit or for those which include a boiler room control
cabinet.
Thecontrolpanelis used tocontrolboilerswith 1 or 2-stage burners.
The control panel S3 equips the boilers GT 330.
optional:
Flue gas thermometer (Package BP28)
2 Presentation
Control panel S3 includes:
- 2 Boiler thermostats
- 1 Safety thermostat
The boiler thermostat regulates the boiler operating temperature.
The safety thermostat with manual reset ensures that the boiler
operates safely.
In the event that there is an abnormal rise in the
temperature in the boiler 110° C. Advise your installation
engineer.
3 Operating principle
The boiler may be regulated:
- either by the boiler thermostats
If the boiler is fitted with a 2-stage burner, each thermostat is
assigned to the operation of one stage. The 2nd stage
thermostat must be set to a value at least 5°C lower than the 1st
stage thermostat.
- or by a control unit located in a cabinet
Operating security is provided by the safety thermostat with
manual reset.

Commissionning
The first start-up is to be performed by your installation
engineer.
Beforestartingtheboiler,checkiftheinstallationis filled with water.
Start the boiler in the following order :
•Boiler temperature regulation by means of the thermostats
`Set the boiler thermostats 3to the desired position. The 2nd
stagethermostatmust be set to avalue at least 5°C lower than
the 1st stage thermostat.
If there is no control unit, we advise you never to set the
boiler thermostat below mark 4 (approx. 40°C) in order to
avoid the risk of combustion products condensing on the
walls of the boiler.
`Ifnecessary, change the position of the maximim temperature.
• Moving the thermostat stop
A factory-set stop limits the maximum temperature to 75 °C.
To move the stop, proceed as follows:
`Pull the thermostat button out carefully (use pliers and a cloth).
`Remove the stop with the pliers.
`Put the stop in the hole of the desired higher temperature
(maximum 85°C).
• Control unit in boiler room electrical cabinet
See the instructions supplied with the control unit and any
remote control unit used.
•Check that safety thermostat 7 is properly set. To do so,
Unscrew the safety thermostat cover and press the reset button
using a screwdriver.
•Set the On/Off switch to 1.

Mounting - Connections
1 Control panel assembly
ZRefer to the technical and assembly instructions delivered with
the boiler.
2 Electrical connections
Only qualified professionnals may carry out electrical
connections, always with the power off.
As the electrical wiring has been carefuly checked in the
factory, the internal connections on the control panel must
not be changed in any way.
Electrical connections must match the electrical diagrams delivered
with the equipment and comply with the instructions in the manual.
Theequipmentmusthaveapowersupplyequipped witha omnipolar
switch with an opening distance above 3 mm.
The earth must comply with the NFC 15.100 (France) or the RGPT
(Belgium) standards.
3 Access to the connection terminal
All connections are made with the terminal boxes designed for
that purpose on the back of the boiler's command board.
Bringtheconnectingcablestothecontrolpanelthroughtheopenings
located on the rear panel of the boiler and 1 or 2 cable channels,
depending upon the type of boiler.
Attach the cables to the cable clamps provided for this purpose.
Keep to the polarity shown on the terminals : phase (L), neutral (N)
and earth 4.

4 Electricity supply - Flow controller
Make the electrical connection to the terminals 1, 2, 3.
Connection to the mains is done using a 3-wire cable with a cross
section of 0.75 mm² on the terminal block (terminals 1, 2, 3).

of 0.75 mm².
The flow controller contact is connected to the safety circuit in series
(between terminal 5on the terminal block and terminal L1 on the
burner, for example).
