EUROSTER 11WB – USER MANUAL
MANUFACTURER: P.H.P.U. AS, ul. Polanka 8a/3, 61-131 Poznań, Poland
1. INTRODUCTION
In order to ensure proper operation of the controller and of the CH and DHW systems, please
read this manual carefully.
2. APPLICATION
EUROSTER 11WB is a state-of-the-art microprocessor-based controller designed for
interoperation with Central Heating (CH) coal- and pulverized coal-fired boilers in systems
equipped with furnace blowers and a domestic hot water (DHW) tank.
The controller measures the temperature in the boiler and in the DHW tank. Depending on
these temperatures, it adjusts the air flow to the furnace and controls the operation of the CH
and DHW circulation pumps.
EUROSTER 11WB controller is equipped with an Anti-Stop function that prevents seizing of an
idle pump rotor. It automatically turns the pumps on for 30 seconds every 14 days when the
heating season is over. Keep the controller turned on to allow the function operation after the
heating season.
