The boiler is switching off by the command of the “Outlet” sensor in the following
cases:
•
Circulation pump stop by reason of power network connecting wire break or
rotor clogging.
•
Presence of the air locks in the heating system.
•
Leakage of portion of heat-transfer agent by reason of the heating system
depressurization.
•
Freezing of part of the heating system because of using water as a heat-
transfer agent.
•
Filter plugging.
The “Outlet” sensor comes into action only in case of emergency or malfunction of
the heating system.
The “Istopnik-103” electronic room temperature indicator and the “Istopnik-203”
electronic programmable room temperature indicator are used only in conjunction with the
“Navigator” control unit.
Relative to the “Inlet” and “Outlet” sensors of the “Navigator” control unit which are
installed on the pipeline, the “Istopnik-103” and “Istopnik-203” temperature regulators are
mounted directly in the heated premises. This increases the effectiveness of the heating
system and makes the heated premises more comfortable. Set up the required
temperatures in accordance with the operation manuals of these devices.
Contrary to the “Istopnik-103”, the “Istopnik-203” is a programmable device by
means of which it is possible to program or to specify the required room temperature
changes by hours of the day or by days of the week.
The “Galan-GSM” cellular monitoring system of the heating equipment makes it
possible to specify and maintain the necessary temperature indoors. This system makes it
possible to connect four additional sensors (security sensor, gas leak sensor, water flooding
sensor, etc.).
The “Galan-GSM” cellular monitoring system of the heating equipment is used in
conjunction with the “Navigator” control unit. Perform the installation in accordance with the
“Galan-GSM” and “Navigator” operation manuals.
Electromechanical model of the automatics. Preparation and putting into
operation.
Connect the boiler to a power network in accordance with the type and power of the
boiler (Diagram 1 or Diagram 2). The “Inlet” temperature sensor, as a rule, is installed on
the pipeline. The “Outlet” temperature sensor is installed on the pipeline coming from the
boiler at 30 cm. from the boiler outlet.
The sensors connecting is performed by means of the copper cable wire with cross
section of 0,5 – 2,5 sq. mm.
A circuit breaker is an automatic safety device which comes into action on current
overload. It is used for switching on and switching off the power supply of the boiler.
A button which is located on the automatic tripping contactor case is used for
switching on and switching off the thermal relay. Under normal operation of the power
supply diagram of the boiler, this button is always in the “on” (pressed) condition. The
actuating of this button signifies that consumption current exceeds the nominal current
because of the malfunction of the boiler (or the power supply diagram) or because of the
water electrical resistance is equal to 3100 Ohm/cm at temperature of +15
º
C. The thermal
relay can be switched on by pressing the button.
Set up a value of the required temperature on the outlet of the boiler (+ 65 ÷ +75
º
C).
Set up a value of the required temperature on the inlet of the boiler. This value
depends on the size of the heated space, quality of the thermal protection of the apartment,
etc. and ranges, as a rule, from +35 to +45
º
C.
