3.11.2 Connection of a room regulator with Op communication
The intelligent room regulator is connected similarly as the connection of the traditional spatial thermostat. The regulator is
connected to the same terminal. It is not possible to connect two types of regulators at the same time!
Technical recommendation during the connection of the regulator with Op communication with the boiler
The connecting cable supplies the regulator for the transfer of the signal of the mutual communication by the protocol
Op between the automatic system of the boiler and the regulator.
Number of conductors in the line :
2
Maximum length of the line
:
50 metres
Maximum resistance of the line :
2 x 5 Ohm
Polarity
:
non polarized connection (conductors can be exchanged)
To prevent the resolution of the communication, it is necessary to use a pair or a shielded pair of conductors!
The connecting cable must not run in parallel or cross the power lines! The cable shielding must be mutually
interconnected and grounded to the faston grounding to the automatic boiler system (the shielding must not
be grounded to the body in several places!). For example, a SYKFY cable is recommended.
Construction:
C
13
- axial horizontal variant
with termination to the
peripheral wall. The
piping can be double,
the termination is either
concentrical or closely
located (location inside
the square with the side
50 cm), so it is affected
by the same atmospheric
conditions.
C
33
- Coaxial vertical variant
with termination on the
roof. The piping can be
double, the termination
is either concentrical or
closely located (location
inside the square with
the side 50 cm and the
distance between the
areas of two holes must
be less than 50 cm) so it
is affected by the same
atmospheric conditions.
C
43
- Separated connection to two pipes of the common shaft. The termination of shafts is either concentrical or closely
located (location inside the square with the side 50 cm), so that it is affected by the same atmospheric conditions.
C
53
- Separated pipe with termination to the peripheral wall or on the roof, in different pressure zones, but under no
circumstances to two opposite peripheral walls.
C
83
- Separated connection with the collection of burnt gases from a separate or common chimney. Supply for the combustion
gas is from the peripheral wall.
