Operating instructions of the Deluxe control panel
Regulation of the boiler:
The boiler is controlled either by the boiler thermostats or by
the SV-matic weather compensator (in option).
For boilers fitted with an SV-matic weather compensator the
temperature of the boiler is controlled by the action of the
regulator on the burner according to the external
temperature. The boiler thermostats will be then set to maxi.
Operating safety is ensured by the safety thermostat with
manual reset.
For boilers fitted with an SV-matic weather compensator
acting on a valve, heating temperature is adjusted by the
regulator on a motorised mixer valve according to the
outside temperature.
Regulation of domestic hot water
With SVR option or SV-matic type B:
The temperature of the domestic hot water is adjusted by a
rheostat 12 located on the SVR or SV-matic weather
compensator. When the domestic hot water is heated, the
burner and load pump start while the heating accelerator
stops; the temperature of the boiler is then regulated by the
limit thermostat incorporated in the SV-matic weather
compensator or mounted on the SVR option (this thermostat
is pre-set from factory at 80°C)
Once the hot water demand is satisfied, the burner stops
and the load pump continues to operate for 4 minutes (timing
adjustable from 30 seconds to 15 minutes). This enables the
residual calories within the body of the heater to be used,
and to complete the heating of the calorifier particularly in
summer.
Start up
Before starting the boiler, check that the installation is
properly filled with water.
Make the start up adjustments in the following chronological
order:
Put the boiler thermostats 5 to the desired position
(altering the position of the stop if necessary).
Important: For boilers fitted with an SV-matic weather
compensator adjust the boiler thermostats to max.
Put the domestic hot water thermostat 12 to the desired
temperature (SVR or SV-matic options). The temperature
of the hot water thermostat must always be lower than
the setting on the first stage boiler thermostat (or the limit
thermostat in the unique case of the SVR option).
Put switch 3:
Either on manual position : Boilers not fitted with an
SV-matic weather compensator.
Or on automatic position “AUTO”: Boilers fitted with an
SV-matic weather compensator.
Check that the safety thermostat 9 is not tripped. To do
this, unscrew the hexagonal cap and using a suitable
screwdriver, press on the reset button.
Put the burner/accelerator switch 2 on winter position
IMPORTANT: In the absence of other settings. it is advised
never to set the boiler thermostat under mark 4 (40°C) so as
to avoid all risk of condensation inside the boiler.
