DESCRIPTION<br />
The sophisticated digital thermostat controller provides display of water flow temperature, set point temperature<br />
and operating status of the boiler.<br />
TEMPERATURE DISPLAY<br />
The RED display indicates the flow water temperature from the boiler. The GREEN display indicates the boiler<br />
water flow set temperature.<br />
The controller is set to <strong>Hurlcon</strong> factory default settings at the time of manufacture. These settings are suitable for a<br />
wide range of applications but may require fine tuning depending on individual project specifications and<br />
characteristics. A detailed Siemens RWF 40 product manual is available on request which details how all settings<br />
are made and the auto tune function is activated.<br />
