This device is an analogue control unit for controlling thermal solar panel systems.
Equipped with 2 on/off relay outputs and 3 inputs for NTC temperature probes, it is able to configure and manage up to 5 different types of solar systems. The solar control unit has been designed to be able to manage the temperature differential between the collector and the boiler and to trigger an integrative source (if the function is activated) when the temperature in the boiler is lower than the integration temperature set. The antifreeze function can be set on 3 levels via an internal connector.
Using the two LEDs located on the right side of the control unit, it is possible to view whether the control unit is powered and the activation/deactivation of the collector pump.
