Other bushings PG9, PG7 are for other signals of the
room thermostat and the 3-ways valve.
3.4.2 Installation of the room thermostat
Connection of the room thermostat is necessary to do
with twin core cable with recommended diameter min.
Cu 0,5 mm2 and length to 25 m.
The cable for the room thermostat is not allowed to be
placed in the same way with supply cord or another
electric or industrial installation. Minimal separation is
10 cm.
The switch board for the room thermostat connection
(24V) is placed in the right part of the control unit from
the front face, the clamp with marking TER, the room
thermostat has clamps with bridge from the factory
setting.
3.4.3 Installation of mode TUV (heating of
sanitary water) and the storage water tank
If you want to heat TUV (heating of sanitary water), it is
necessary to connect through the electric boiler with
TUV connection set and extend the control unit with
TUV mode.
The complete set consists of:
mode TUV
sensor TUV
3-ways valve
connection cable of TUV mode to the control unit
connections parts and materials
instruction manual
Connection of TUV mode is carried on with the flat
conductor to the connector on the left side of the control
unit (marked TUV). It is necessary to connect a phase 230
V to switchboard X2 according to the circuit diagram with
the conductor enclosed.
Connection of phase conductors of 3-ways valve is carried
on to the switchboard on the TUV mode. Connection of
“working zero” is carried on to the switchboard X2, the
sensor of TUV temperature is connected to the
switchboard on the TUV mode.
More detailed description is enclosed in the TUV
connection set (package).
TUV mode connection through is able to
carry on only responsible service
person.
3.4.4 Installation of GSM mode control
If you want to use the GSM control of the electric boiler
then it is necessary to extend the control unit with GSM
mode.
The GSM mode consists of:
GSM modem (with basic type of aerial)
flat conductor for connection through
connections parts and materials
instruction manual
GSM modem connection is carried on with the flat
conductor to the switchboard GSM on the left part of the
control unit. The flat conductor has to be pulled through
the inlet of upper cover of the boiler. GSM modem is
necessary to screw or to fix another way to the cover of
the boiler to avoid its dismantling. For GSM modem
mounting use inlets on the upper cover of the boiler. If you
have a not strong GSM signal from network then it is
possible to buy additional external aerial determined for
GSM modem SIEMENS.
Aerial parameters:
Frequency scale: 900/1800 MHz (Dual-band)
Impedance: 50 Ohm
Connector: SMA (male)
More detailed description is enclosed in the TUV
connection set (package).
3.5 Heating system
The pipe system of heating system has to be made to
avoid forming of air bubbles and to make easy the process
of deaeration. Deaeration valves have to be placed on
each highest heating system place and on all radiators.
We recommend making the heating pipe from copper.
Plastic pipes have to fulfill requests of heating resistance
and have guaranteed heat resistance have not to loose
parts in the heating water to avoid paralysation of
regulation and safety function components, including the
pump.
The boiler has to be installed in opened or closed heating
system according to the normative conditions
(overpressure of heating system, maximal volume of
heating system).
The boiler could be used for underfloor heating, minimal
temperature of heating water is 30°C. The boiler has not
equipped by the sensor of maximal temperature of
heating water for underfloor heating,, it has to be carried
on by external thermostat connected by its clamps to the
electric boiler.
Using of defrost mixture
We don´t recommend to use defrost mixtures due to their
characteristics, some of them are not convenient for the
boiler operation, concretely reducing of heat
transmission, big volume elasticity, ageing, breakdowns of
rubber parts. It is necessary to think about to use them
inevitable. Regarding inevitable situation it is allowed to
use the defrost mixture Alicol Termo according to
experience of the producer that the boiler operation is not
reducing.
If you are not able to use this defrost mixture and you will
protect your heating system with another defrost mixture
then guarantee claim will not be accepted
3.6 Expansion vessel
The expansion vessel has these parameters:
Total volume 8 dm3
Overpressure of nitrogen filling 1,2 bar
Size 8 l
The expansion vessel eliminates warm elasticity of
heating medium (water) in the heating system therefore
it is necessary to have its sufficient volume. The size of
expansion vessel is projected by a responsible person
technician of heating system project. Below mentioned
is a graph for your basic orientation knowledge of
dependency.
