INSTRUMENT CONTROL
The heat generator type LH is equipped with an
individual thermostat, it is located on the side wall of the
control panel on the side of the discharge fan.
Temperature scale of the thermostat: from 0 to 40 º C.
The automatic mode of operation of the device occurs
by turning on / off the device, which, depending on the
air temperature in the room in relation to the
temperature set on the device, turns on or off.
An external thermostat can also be connected to the
device. For a diagram of the connection of the external
thermostat, see. Appendix No2.
The device can operate in three operating positions :
-
VENTILATION
-
VENTILATION + HEATING
-
HEATING
VENTILATION:
Turning on the power supply of the device, press the
white button on the control panel with the inscription fan,
the device will start the fan, and will work in ventilation
mode, in which the light signal of the white button is
constantly lit. To turn off the ventilation mode, you must
press the white button again.
VENTILATION + HEATING:
Having turned on the power supply of the device, press
the green, then the white button on the control panel, in
this case the ventilation mode is constantly working,
and the heating mode is turned on periodically
depending on the air temperature in the room in relation
to the set on temperature device.
In this position, the light signal should be lit on both
buttons. When you press the white button again , the
ventilation mode is turned off, and the device will
operate in automatic heating mode.
It is possible that when you press the white button
again, the light signal will not go out, this is due to the
fact that the shutdown was made at the time when the
fan was started in heating mode.
HEATING:
After turning on the power supply of the device, press
the green button on the control panel, in this case the
heating mode is constantly running. If only the light
signal of the green button on the thermostat is lit , this
means that the air temperature is in a room higher than
the specified one. This is
will last until the air temperature in the room drops below
the temperature set on the thermostat and the
thermostat starts the heating mode, in which the light
signal of the white button should light up. After reaching
the set temperature in the room, the thermostat turns off
the heating mode, stops the fan and the light signal of
the white button goes out.
COMMISSIONING
Starting the device
If you have selected the above mode of operation of the
device, then press the button or buttons you need and
the device in accordance with this will launch the
program of your choice .
The ignition process starts from 30 seconds. Purge.
during this purge the airflow controller analyzes the
correct operation of the fan and its ability to create the
necessary airflow . if the airflow sensor detects the
correct operation of the fan then after the expiration
30 sec. the electronics will start the spark, at the same
time as the solenoid valve opens, opening the gas
access to the combustion chamber, where the gas-air
mixture is ignited by means of sparking. If the ignition
was successfully performed, the ionization controller
the flame detects the correct pattern of combustion, the
device begins to work and perform its heating functions.
In those countries where the installation of a minimum
gas pressure sensor is mandatory , the start of the
device will occur only if the pressure of the network gas
exceeds the specified minimum. If during the operation
of the device, there is a pressure drop in the network,
the minimum gas pressure sensor will turn it off.
Malfunctions (RESET)
During the operation of the device , malfunctions may
occur, controlled by the safety system of the device.
The basic model of the device is equipped with three
controllers:
-
ionization flame controller
-
Airflow sensor
-
overheating sensor
In some countries, such as Ukraine, Russia, etc. a
fourth sensor is required
–
a minimum gas pressure
sensor. The instruments supplied to these countries are
equipped with four sensors.
These sensors independently monitor the correct flow
