1. INTRODUCTION
In order to guarantee correct operation of central heating controller and installations one
should familiarize oneself with the present user manual.
2. INTENDED USE
EUROSTER 11M is a modern, microprocessor controller for regulating temperature with the
use of mixing valve, equipped in limit switches.
Depending on configuration, it regulates temperature in heating circuit (e.g. floor heating) or
boiler return temperature. It also controls central heating pump operation by switching it off
when the boiler is damped.
Temperature is regulated with the use of PI algorithms (proportional - integral) which allows
for fast and accurate regulation for varied loads.
In temperature regulation mode for the heating circuit, the controller can cooperate with any
room regulator which has a no-voltage output, normally open (NO) i.e. all EUROSTER
regulators).
The EUROSTER 11Z controller has been equipped in an ANTY STOP system to prevent
formation of deposits on motors of unused pumps. After finishing heating season it
automatically launches the mixer and the pumps every 14 days. In order for the system to
work out of season, the controller must be left on.
3. CONTROLLER FUNCTION
 keeps constant water temperature: in the central heating circuit or in boiler return
 possibility of connecting room regulator
 Anty-Stop function to protect pumps and valve against stoppage
 frost protection
 pump operation test
 temperature reading correction
