wall.
By following the above guidelines, unwanted
starting and stopping of the system can be avoided
and optimal comfort in the heated space can be
guaranteed.
4.4.5.2 0-10 V input
Control via 0-10 V signal is alternative to control via
DDC panel or external request.
The 0-10 V signal connection is only available on AY 35
and AY 50 models.
Either the water temperature setpoint or the power value
can be communicated alternatively via a 0-10 V analogue
signal.
The meaning to be given to the 0-10 V input is chosen by
appropriately configuring the boiler board parameters
(Paragraph 5.3 p. 31).
The 0-10 V signal should be connected to the 0-10
terminals as shown in Figure 4.10 p. 30.
The cable may not be longer than 30 metres.

5 FIRST START-UP
First start-up entails checking/setting up the com-
bustion parameters and may exclusively be carried
out by a Robur TAC. NEITHER the user NOR the in-
stallation technician is authorised to perform such
operations, under penalty of voiding the warranty.
5.1 PRELIMINARY CHECKS
5.1.1
Preliminary checks for first start-up
Upon completing installation, before contacting the TAC
the installer must check:
▶
Water, electrical and gas systems suitable for the re-
quired capacities and equipped with all safety and
control devices required by the regulations in force.
▶
Absence of leaks in the water and gas systems.
▶
Type of gas for which the appliance is designed (natu-
ral gas or LPG).
▶
Supply gas pressure complying with the values of
Table 3.3
p. 21.
▶
Correct operation of the flue exhaust duct.
▶
Power supply mains complying with the appliance's
rating plate data.
▶
Appliance correctly installed, according to the manu-
facturer's provisions.
▶
System installed in a workmanlike manner, according
to national and local regulations.
5.1.2 Abnormal or hazardous installation
situations
Should any abnormal or hazardous installation situations
be found, the TAC shall not perform first start-up and the
appliance shall not be commissioned.
These situations may be:
▶
Failed compliance with minimum clearances.
▶
Insufficient distance from combustible or flammable
materials.
▶
Conditions that do not warrant access and mainte-
nance in safety.
▶
Appliance switched on/off with the main switch, in-
stead of the provided control device.
▶
Appliance defects or faults caused during transport or
installation.
▶
Gas smell.
▶
Non-compliant mains gas pressure.
▶
Non-compliant flue gas exhaust.
▶
All situations that may involve operation abnormali-
ties or are potentially hazardous.
5.1.3
Non-compliant system and corrective
actions
Should the TAC find any non conformities, the user/install-
er is bound to perform any corrective procedures required
by the TAC.
After performing the remedial actions (the installer's re-
sponsibility), if the TAC deems that safety and conformity
conditions are in place, first start-up may be effected.
5.2 HOW TO ACCESS THE BOILER
For all control and maintenance operations, it is necessary
to remove the front panel of the boiler as described below.
The other panels cannot be removed as they are structural.
Remove the front panel of the boiler as follows:
1. Open lock A with the triangle key supplied with the
appliance.
2. Remove front panel B by tilting it outwards and pulling
it upwards.
