GENERAL INFORMATION
INTRODUCTION
The boiler operation control unit ESTYMA control M RS is a modern
microprocessor system which controls not only the boiler, but also the central
heating system in weather-compensated and hot tap water modes.
The unit controls the amount of the fuel fed through on and off operation of the
motor of the fuel feeder, and the amount of the air supplied to the combustion
process. Thanks to solid state relays (SSRs), the blower has variable speed
control and the reliability of the unit controlling the feeder motor has been
greatly increased.
Automatic fuel ignition. The M RS ESTYMA control unit provides automatic
fuel ignition in the retort.
Measurement of waste gas temperature. The control unit measures waste
gas temperature which is an essential parameter in a boiler with automatic start
up. Waste gas temperature readouts are also very useful when inspecting the
boiler and adjusting its operation.
Weather-compensated control ensures highest thermal comfort because the
temperature of the heating medium is controlled depending on the outdoor
temperature. Control is effected through the mixing valve actuator.

Thanks to an advanced operation algorithm and the possibility of controlling
numerous parameters, the unit can be very flexibly adjusted to the needs of
the heating system.
The controller has an output testing function. The function is available in the
MAINTENANCE MODE and it allows to check the correctness of electrical
connections and the working order of the controlled equipment (pumps, blower,
feeder, mixing valve actuator) prior to starting the boiler.
A large alphanumeric display facilitates communication between the unit and
the user and the interface is very easy to use.
A new intuitive menu in several languages: Polish, English, German, French,
Lithuanian, Russian.
A Lambda sensor ensures optimum supply of air to the combustion process,
thereby simplifying the work of the operator; it also reduces fuel consumption
and improves combustion, reducing emissions of harmful substances to the
environment (optional boiler equipment).
The pneumatic fuel feeding control system allows the boiler to operate for long
periods of time without the need to add fuel.
The heat exchanger cleaning control system ensures that the boiler retains
high efficiency without the need to clean the exchanger.

SAFETY PRECAUTIONS
Warning – risk of electric shock.
Before assembly or disassembly of the unit, disconnect the power supply in the
switchgear.
Read this operation manual carefully and thoroughly before using the unit.
Keep this operation manual and refer to it whenever you work with this unit in the
future.
Apply all the rules and heed all the warnings included in the unit operation manual.
Make sure that the unit is not damaged. In case of any doubts, do not use the unit and
contact the supplier.
In case of any doubts concerning the safe operation of the unit, contact the supplier.
Pay special attention to all warning signs on the unit casing and its package.
Use the unit as intended.
The unit is not a toy. Do not allow children to play with it.
Under no circumstances children should be allowed to play with any parts of the
package of the unit.
Access to small parts such as clamping screws or bolts should be secured against
children. Such elements may be delivered with the unit and may result in choking when
swallowed by a child.
Do not make any mechanical or electrical changes to the unit. Such changes may cause
the unit to malfunction and fail to meet the relevant standards, leading to an adverse
impact on the performance of the unit.
Do not insert any objects into the unit through openings (e.g. ventilation grills), as this
may cause short circuiting, electric shock, fire or damage to the unit.
Do not allow water, humidity or dust to enter the unit, as this may cause short
circuiting, electric shock, fire or damage to the unit.
Provide adequate ventilation of the unit, do not cover or block the ventilation grills, and
ensure that there is free flow of air around the unit.
The unit should be installed indoors unless it is adapted for outdoor operation.
Do not expose the unit to mechanical impacts and vibrations.
When connecting the unit to power supply, make sure that the parameters of the
supply network are within the unit’s operating range.
In order to avoid the risk of electric shock, connect the unit to a socket with an
earthing pin. The socket must be properly earthed by a licensed electrician.
When connecting the unit, make sure that it does not overload the electrical circuit.
Avoid connecting the unit to one circuit with motors and other equipment that causes
impulse interference (e.g. washing machines, fridges, ...)
It is absolutely necessary to cut off power supply before connecting any cables or
peripherals to the unit.
Remove the plug from the socket in order to completely de-energize the unit, especially
if you do not intend to use the unit for a longer period of time.
Protect the power lead against damage; it should be laid in a way that ensures that
nobody treads on it; no objects should stand on the power lead.
All electrical connections must be as shown in the electrical assembly drawings and
must comply with national and/or local regulations concerning electrical connections.

This unit contains no parts that may be replaced by the user. All maintenance work
except for cleaning, fuse replacement (when the unit is de-energized), and function
setting, should be performed by an authorized service provider.
Before doing any maintenance work, you must cut off the power supply to the unit.
Do not clean the casing of the unit with petrol, solvents or any other chemicals that
may damage the casing of the unit. Using a soft cloth is recommended.
If the power lead is damaged, the unit must not be used. The damaged lead must be
replaced by a maintenance service provider, with a new one having the same
parameters as the original lead.
DISPOSAL OF OLD EQUIPMENT
This electronic equipment is made of materials which are partly
recyclable. Therefore, when the equipment has reached the end of
its service life, take it to an electrical and electronic equipment
recycling centre or to the manufacturer. The equipment must not
be disposed of with other household waste.
APPLICABILITY OF THE MANUAL
This instruction manual is applicable to M RS ESTYMA control units with software
versions up to 9.1. The software version is displayed in the welcome message
after connecting the unit to the power supply. Description of changes in higher
versions is available on the manufacturer’s website at: www.estyma.pl
