In all other cases, use the GHP probe supplied installing it down-
stream of the primary/secondary decoupling or the optional
buffer tank (see detail 1 Figures 3.5 p. 29 and 3.6 p. 29). This
probe must be connected to the AUX PROBE 1 input as shown
in Figure 4.8 p. 38, after disconnecting the factory wired one.

The outdoor temperature probe (available as OSND007 option-
al) must be connected to AUX PROBE 2 input, as shown in Figure
4.8 p. 38.
With reference to Paragraph 1.8
p. 21, this probe is recom-
mended for applications in which control type (2) or (3) is used
together with adjustment based on climatic curve.

5 FIRST START-UP
First Start-Up entails checking/setting up the combus-
tion parameters and may exclusively be carried out by a
Robur TAC. NEITHER the user NOR the installation tech-
nician is authorised to perform such operations, under
penalty of voiding the warranty.
The installer is obliged to carry out preliminary checks
described in Paragraph 5.1
p. 38.
5.1
PRELIMINARY CHECKS
Paragraph dedicated to the installer.
Preliminary checks for First start-up
Upon completing installation, before contacting the TAC the in-
staller must check:
▶
water-heating, 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 (methane);
▶
supply gas pressure complying with the values of Table
3.3 p. 32, with max tolerance ±15%;
▶
Power supply mains complying with the appliance's rating
plate data;
▶
appliance correctly installed, according to the manufactur-
er's instructions;
▶
system installed in a workmanlike manner, according to na-
tional and local regulations.
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:
▶
appliance installed inside a room;
▶
failed compliance with minimum clearances;
▶
insufficient distance from combustible or flammable mate-
rials;
▶
conditions that do not warrant access and maintenance in
safety;
▶
appliance switched on/off with the main switch, instead of
the control device provided (OQLT019, OCDS007, or external
request);
▶
appliance defects or faults caused during transport or instal-
lation;
▶
gas smell;
▶
non-compliant mains gas pressure;
▶
non-compliant flue gas exhaust;
▶
all situations that may involve operation abnormalities or are
potentially hazardous.
Non-compliant system and corrective actions
Should the TAC find any non conformities, the user/installer is
bound to perform any corrective procedures required by the
TAC.
After performing the remedial actions (the installer's responsi-
bility), if the TAC deems that safety and conformity conditions
are in place, "First start-up" may be effected.
