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.
