It is necessary to use the connection diagrams specified in the Operation manual to
connect the “Galan-GSM” cellular monitoring system of the heating equipment, “Navigator”,
“Istopnik-103” and “Istopnik-203” electronic temperature regulators. Follow exactly the
instructions of operation, installation, and safety control.
The “Inlet” temperature sensor is installed on the pipeline (return pipe). The “Outlet”
temperature sensor is installed on the pipeline coming from the boiler (vertical standpipe) at
30 cm. from the boiler outlet (boiler connection).
The recommended optimal operating temperatures of the heat-transfer agent on the
inlet and outlet of the boiler are specified in the “Introduction” section of the given
Operation manual. The observation of these temperature modes assures the greatest effect
of using the electrode boiler.
The range of thermoregulation of the “Navigator” temperature regulator on an outlet
of the boiler stretches from +10 to +90° С (“Outlet” indicator). The range of
thermoregulation of the “Navigator” temperature regulator on an inlet of the boiler stretches
from +10 to +60° C (“Inlet” indicator).
When employing the “Istopnik-103”, “Istopnik-203”, and “Galan-GSM” temperature
regulators the temperature is measured directly in the heated premises. The usage of these
devices increases the effectiveness of the heating system and makes the heated premises
more comfortable.
Use a copper wire with a value of cross section lying in the range between 0,5 to 2,5
sq. mm for installation of the automatic control unit of the heating system. A wire make-up
should be specified in the project documentation of your heating system and in the
automatic control unit operation manual. In case of applying copper stranded wire use a
thimble but do not tin an end of the wire because it may bring into existence a bad contact.

In the course of starting-up and adjustment tasks and on the basis of the specific
situation the following temperatures are set on the “Navigator” temperature regulator:
•
Temperature on the outlet of the boiler (a value belonging to the
recommended optimal operating temperatures range which stretches from
+65 to +75
º
C) at which the boiler is switching off obligatory in any condition
(temperature which is set on the boiler outlet). As a rule, this temperature is
equal to +70
º
C.
•
Temperature on the inlet of the boiler (a value belonging to the recommended
optimal operating temperatures range which stretches from +35 to +45
º
C)
at which the boiler is switching off obligatory in any condition (temperature
which is set on the boiler inlet).
A hysteresis setting (specific number of Celsius degrees by which the temperatures
on the inlet and outlet of the boiler should be decreased in comparison with the specified
temperatures in order that the temperature sensors on the inlet and outlet of the boiler
(“Inlet” sensor and “Outlet” sensor) should send commands for switching off the boiler) is
also set on the “Navigator” temperature regulator.
A value of the hysteresis setting belongs to the temperature range of the adjustable
hysteresis of the “Navigator” temperature regulator. This temperature range stretches from
1 to 9
º
C.
A hysteresis setting for the “Outlet” sensor, as a rule, is equal to 9
º
C.
A hysteresis setting for the “Inlet” sensor is strictly individual for every heating
system. It is defined both by the objective factors (for example, match between the heat
losses of the heated premises and the power of the heating system) and by the subjective
factors (for example, requirements on the comfort of the heated premises, requirements on
the operating economy of the heating system).
With the exception of particular cases, in the course of the cold season the hysteresis
settings, as a rule, are not changed.
The boiler is switching off, as a rule, by the command of the “Inlet” sensor.
In case of emergency or malfunction of the heating system (in consequence of
deterioration of the heat-transfer agent circulation or increase of temperature on the outlet
of the boiler) the boiler is switched off by the command of the “Outlet” sensor.
