1. INTRODUCTION
In order to guarantee correct operation of central heating and hot usable water controller and
installations one should familiarize oneself with the present user manual.
2. INTENDED USE
EUROSTER 11Z is a modern controller that independently controls operation of two pumps:
central heating circulating pump and hot water tank loading pump with the possibility of
prioritizing hot water pump.
The controller switches off central heating pump if temperature of the heating boiler falls below
a predefined value.
If tank temperature falls down, tank loading pump will be switched off. Moreover, the controller
protects the tank against cooling down in case of low temperature of boiler extinction. Hot
water priority function allows for the fastest possible way of heating the tank.
3. CONTROLLER FUNCTION
• prevents boiler sweat
• keep constant temperature in the tank
• switches on the hot water priority function
• blocking function against tank cool down
• anti-stop function to protect pumps against stoppage
• frost protection
• pump operation test
• temperature reading correction
The EUROSTER 11Z controller has been equipped in an ANTY STOP system to prevent seizing
of rotors of unused pumps. After finishing heating season it automatically launches the pumps
for 30 seconds every 14 days. In order for the system to work out of season, the controller
must be left on.
