3. EUROSTER 1100M USER MANUAL 1 EUROSTER 1100M 1 FUNCTION EUROSTER 1100M is a processor based unit used for controlling the operation of actuated 3 way valves equipped with limit switches installed on hydronic heating systems In heating systems supplied by a coal fired boiler EUROSTER 1100M controls the operation of the valve and maintains the return water temperature at a constant level With the return temperature set at an optimum level the boiler does not sweat during heating up of system water Moreover this has a positive effect on the boiler life The temperature is measured by a digital sensor installed on the return pipe EUROSTER 1100M is equipped with ANTI STOP system to prevent seizure of the valve in idle periods Throughout the non heating season it automatically cycles the valve for 30 seconds every 14 days with the temperature below 30 C For this function to be operational the thermostatic controller must not be switched off at the end of heating season Valve status indication opening movement Valve status indication closing movement Hysteresis and temperature adjustment Response speed temperature On off mains switch Temperature sensor Valve supply 230 V AC Controller supply 230 V AC Sow Se 2 INSTALLATION DANGER Prior to installation by a qualified electrician make sure that the unit has been disconnected from power supply to avoid the risk of electric shock Units with
