central heating (CH) pump.
Before you start using the controller, please read this instruction
carefully.

APPLICATION
AURATON S03 RTH is intended for automatically switching on and off
circulation pumps depending on the temperature. The controller-
pump assembly forces the water to circulate in the central heating
system with a coal-fired boiler or a gas boiler. The controller's sensor
measures the temperature of the water on the supply side of the CH
system. In a CH system with a coal-fired boiler, the controller switches
off the circulation pump after the flame in the boiler is extinguished.
Pumping of water is not recommended when the flame is extinguished
because the air draft into the chimney causes faster cooling of the
water in the boiler faster than in the radiators. The optimum
temperature can be set on the controller's scale (most often 40 °C).
In a CH system with a gas boiler, the temperature set on the controller
must be lower than the temperature set on the CH boiler. If the
temperature is set on the controller above the dew point, it prevents
condensation in the boiler during the heating of the water in the CH
system.
The AntyStop (AS) system installed in the Auraton S03 RTH controller
prevents seizure of the rotor of an unused pump. Also, a built in
processor starts the pump every 14 days for 30 seconds after the
heating season is over. In order for the system to work after the heating
season, the controller must be switched on with the AS function active
at all times.
