4.6. The functions of EKOSTER 2
Use
The microprocessor temperature regulator for central heating boiler is designed to control the air
blow in wood-red boiler and to actuate the circulating pump in central heating system
The regulator performs the following functions:
• maintaining the set temperature of boiler by controlling air blow,
• smooths start-up of blower,
• setting the blower power (service mode),
• programmable boiler “blow-through”,
• automatic control switch-off after boiler burnout (extinguishes),
• blower disable when feeding the boiler,
• control of central heating circulating pump depending on its set operating temperature,
• „COMFORT SYSTEM”,
• protection against freezing or overheating of boiler,
• signalling of temperature sensor’s damage,
• regulating the brightness of display - increased during read out and change of regulator set-
tings,
• control panel connecting possibility,
• room thermostat cooperation,
• automatic turning off in case of wrong burning up in the boiler.
Regulator’s working description
After switching on, the regulator passes into state signalled by switching on of cor-
responding lamp. Operation commences after pressing button or automatically when
boiler’s temperature rises above operating threshold - that is, difference between set boiler
temperature and factory-set temperature difference “dt”. Automatic transition into state
occurs 30 minutes after boiler temperature drops below operating threshold. CONTROL recepta-
cle is for connecting remote control.
Pushbuttons and serve to change the settings. During normal operation, pressing them
causes display and change of set boiler temperature. Pressing and holding pressed causes
increase in speed of temperature setting change.
Pressing the button causes:
• with temperature below operating threshold: switching on or switching off control, signalled
by or indicators respectively,
• with temperature above operating threshold: blower disable signalled by pulsation of
indicator, enabling feeding of fuel into the boiler. Automatic return to operation .

NOTICE!
If the “Er” appears on the screen it means that temperature either raised over 99°C, it
decreased below -9°C or the sensor got damaged. To secure together the boiler and
installation up to the time of the sensor replacing pump should be continuously on till
that time.
