4.3 Control, regulation and safety elements
The boiler regulator
serves for an automatic control of boiler activities and elements. It processes the input
data from the sensors and external control elements (see chap.8.1) and according to parameters set by the
manufacturer or user it controls automatically the boiler activity in required regimes.
The regulator also enables to operate the boiler manually which can be advantageously used to at boiler
commissioning.
A high variability in setting the limit and operating parameters makes it possible for both the manufacturer
and user to use fully and effectively the characteristics of automatic boilers for pellets it means an
economical boiler operation, controlled combustion process thus the toxicants content in flue gases
minimization.
Emergency thermostat
is installed in the regulator box and its function is to protect the heating system
against overheating. The manufacturer set it on 95 °C, it means the temperature higher than it can be set as
the required temperature at the boiler. In case that the emergency thermostat was switched off (the red
control lamp on regulator is on) the deblocking process must be done manually.
In case that the emergency thermostat was switched off repeatedly the boiler must be shut down and the
reason for repeated boiler overheating must be found out.
Programmable regulator
- digital programmable indoor device (like HONEYWELL CM 27) intended for
automatic heating regulation in cottages and flats.
-
7-day heating time programme
-
6 time sections during a day with individual temperature, setting range 5 – 30 °C with 0,5 °C step
-
programmable antifreeze protection for the season when the building isn’t used
-
information about the real and required temperature in the room
ATTENTION! For boiler control there can only be used the free potential-free contact, switching
voltage is 5 V DC.
Thermomanometer
serves for determination of heating water output temperature and its pressure in
heating system and it is installed in the upper part of boiler shells. The clack valve and the reservoir for
thermomanometer connection are situated in the upper part of rear boiler section.
Forced-draught fan
for combustion air is mounted directly in combustion chamber body. The combustion
air volume is regulated by a throttling flap. The flue gases flow from the boiler to the chimney can be reduced
by a smoke flap. This is controlled by a handle with a tow bar in the upper left part of boiler drum next to the
stoking door.
The air rose of stoking door
cannot be used at VIADRUS HERCULES ECO boiler with automatic
combustion of wooden pellets and it
must be permanently closed
.
Cleaning cover of the smoke adapter
positioned in its lower part serves for flue gases ways cleaning.
