FIELD OF APPLICATION

EUROSTER 11Z is a modern microprocessor-based controller used to control central heating
(CH) system circulation pump and utility hot water (UWH) tank pump. The controller may be
turned in the UHW priority mode.
The controller will turn the CH system circulation pump OFF if the boiler temperature has
dropped below some defined preset temperature. The controller will turn the UHW tank pump
ON if the tank temperature has dropped below some defined preset temperature. Additionally
the controller protects the UHW tank against chill-out in case temperature of the heat source is
too low (e.g. since the boiler is extinct).
The UHW priority mode may be used to heat the UHW tank up as soon as possible.
The EUROSTER 11Z controller features the ANTY STOP
function that prevents idle pump rotors against seizing. Once
the heating season is over, every 14 days the function
automatically turns ON the pumps for 30 seconds. To that end
the controller must be left powered up.
