ENGINEERING SPECIFICATIONS:
The SunEarth Solflux control has a compact designer housing allowing universal use. The SESF-3221 has extensive functionality for control of solar water heating systems and provides additional system monitoring functionality. When used in conjunction with an external pressure sensor, the “System pressure monitoring” controller function provides additional system monitoring and security. An additional controller output that can be individually customized for additional controller functions is also provided.
The variable input voltage range allows universal use of the device worldwide. The SESF-3221 has two powered outputs, that can also be configured along side s 0-10 VDC or PWM output for controlling high efficiency pumps and a non-powered relay switched output for additional controller functions of devices up to 20amps. The equipment is rounded off by three inputs for recording temperatures.
The integrated heat energy measure system allows the acquisition of numerical information on the solar yields of the system. For more demanding requirements, this can be expanded using an external pulse encoder or an additional Grundfos Direct Sensors™. All controller data is available for Two-way communication via web or mobile application.
Five pre-programmed systems enable universal usage. The Solflux SESF-3221also provides important monitoring and safety functions such as special error messages to quickly troubleshoot faults.
