3. EUROSTER 1100Z USER MANUAL 1 EUROSTER 11002 Euroster 1100Z is a processor based electronic temperature controller designed to control DHW and heating water circulating pumps It operates with two sensors and according to two independent temperature settings When incorporated in hydronic heating systems supplied by coal or gas fired boiler it controls forced circulation of heating water The function of EUROSTER 1100Z is to maintain the temperature of water at a constant level on the hot water cylinder or on the DHW circuit The unit features cylinder cooling protection to avoid excessive drop of temperature on the hot water cylinder following the decrease of heating boiler temperature and DHW priority option EUROST ER gt sadi EUROSTER 1100Z is equipped with ANTISTOP system to prevent seizure of pump rotor in idle periods Throughout the non heating season every fortnight the integral processor of EUROSTER 1100Z will automatically cycle the pump for 30 seconds For this function to be operational the thermostatic controller must NOT be switched off at the end of the heating season Status indication DHW mode Status indication heating mode DHW heating mode switch temperature adjustment up DHW heating mode switch temperature adjustment down On off switch for continuous pump operation on DHW heating circuits On off mains switch Power supply to DHW pump 230 V AC Temperature sensor on DHW circuit Temperatur
4. ating water sensor has risen by 2 C above the setpoint and it is switched off when the temperature has dropped by 3 C below the setpoint With active DHW priority the heating water circulating pump will be switched on only when the DHW pump is Off Cooling protection off heating of water in the cylinder is governed solely by the temperature measured by the DHW sensor The pump is switched on when the temperature has dropped below the setpoint and switched off when it has risen by 1 C above that setting The operation of the heating water pump is the same as described for operation with active cooling protection EUROSTER 1100Z USER MANUAL 4 h continuous operation mode e set the toggle switches and gt to position I e green LED is on to indicate that the heating water circulating pump operates continuously irrespective of the selected operating mode DHW heating temperature setpoint and the current temperature as measured by the sensor e set the toggle switch to position I and toggle switch gt to position II e red LED is on to indicate that the DHW circulating pump operates continuously irrespective of the selected operating mode DHW heating temperature setpoint and the current temperature as measured by the sensor 4 COMPLIANCE WITH STANDARDS AND CONFORMITY CERTIFICATES EUROSTER 1100Z is in compliance with the following EU directives EMC LVD The CE certificate of conformity is posted on our website
