PARAMETER DESCRIPTION SETTING VALID RANGE DEFAULT RANGE
4.40
UNIT ID CODE: unequivocally identifies each machine
connected in a CAN network; it is to be set with a different
value on every nit, regardless of the type of unit and the
systems on which it works.
The value to be set for this parameter is the
numeric code assigned to the current machine. 0 to 478 For single unit = 0
For Link= from 0 to 4
4.150 SYSTEM CODE – HOT MODULE:
unequivocally identifies the system on which the unit (hot
module) works, if present.
The value to be set for this parameter is the
numeric code assigned to the system on which
the hot module of this unit works, if present. 0 to 15 0

You will need: the appliance connected to the gas and electricity supply: switched off
and with the gas cock closed; front panel removed.
Check the dynamic gas mains pressure
Connect the manometer to the gas intake (see detail D, Figure 6.1 Gas 1.
valve → 49).
Open the gas valve and check that the grid static pressure complies to the value 2.
reported in Table 2.4 Network gas pressure → 12 (with a tolerance of ±15%).
If the static mains pressure is greater than 50 mbar DO NOT switch on the
appliance!
Give the consent signal for operation.3.
After some seconds of operation, check that the grid dynamic pressure complies 4.
with the value reported in Table 2.4 Network gas pressure → 12 (with a tolerance
of ±15%).
