1. INTRODUCTION

Carefully study this user manual to learn how to correctly operate the EUROSTER 11/11C
central heating (CH) pump controller.

2. FIELD OF APPLICATION

EUROSTER 11/11C is an electronic controller used to automatically turn ON/OFF CH system
circulation pump depending on CH system water temperature. The pump may circulate water
through a system heated by a coal- or gas-fired boiler. Water temperature is sensed by a
sensor located at the CH system inlet.
The controller will also turn the pump OFF as soon as coal-fired boiler flame is put out. Water
should not be circulated unless it is heated by the boiler since chimney air draft cools down the
boiler water much faster than the radiator water.
Controller is equipped with a knob used to preset optimum CH system water temperature
(most often around 40ºC). If the controller cooperates with a gas-fired boiler, its set
point MUST BE LOWER than the boiler thermostat set point. Set the controller set
point higher than the dew point in order to prevent boiler sweat during the process
of heating the water up.
The EUROSTER 11/11C controller features the ANTY STOP
function that prevents idle pump rotors and valves against
seizing. Once the heating season is over, every 14 days the
function automatically turns ON the pumps and the valves for
30 seconds. To that end the controller must be left powered up.
