EUROSTER 11M – USER MANUAL

OPERATION WITH ROOM REGULATOR
In central heating circuit regulation mode the
EUROSTER 11M
controller can cooperate with
any room regulator which has a no-voltage output, normally open (NO) i.e. any EUROSTER
controller.
Regulator switch off (outlet divergence) will result in closing the mixing valve and subsequently
in switching the pump off.
Methods for connecting room regulator have been described in point 5.a.

ANTY-STOP
Pump anty-stop system switches the pump and mixing valve on immediately after each
controller switch on (also after restoring to factory default or change of backlight mode) and
then every 14 days. During its operation "AS" keeps pulsating on the screen.
In order to prevent the risk of circuit overheating, the procedure is as follows:
The pump is switched off and the mixer fully opened
The mixer is closed; after 50s the pump is switched on.
If during the activity period of the ANTY STOP system, an emergency situation (sensor
overheating or damage) occurs, operation of the ANTY STOP system will be interrupted.

TYPICAL DAMAGES AND REPAIR METHODS
Device is not working
Burnt fuse or memory software fault - send the device to service.
Screen and sensor symbol blinking, "Sh" or "OP" appears
Short sensor (
Sh
ort) or open sensor (
OP
en) - check sensor cable for which a symbol is
pulsating or send the device together with the sensor for service.
Pump or mixer is not working
Device switched off - make sure that relevant symbols on the device are visible. If not, check
the settings. Restore to factory settings (chapter 9).
Connection error - check.
Continuous mixer operation
Dynamics (setting 3.) set to a too high value - correct settings.
Hysteresis (setting 2.) set to a too small value - correct settings.
Knob works in an unforeseeable manner
Pulse generator damage - send device to service.
