2.0 System Overview
T1 : Temperature sensor in solar collector
T2 : Temperature sensor in hot-water tank
: Circulation pump
: Solar heat regulator
The SH-E01 regulator is used for controlling utility water installations
consisting of a solar collector circuit and a hot water tank, where the
utility water is heated by solar energy.
The solar heat circuit circulation pump is controlled by the diff erential
temperature between the solar collector and the tank bottom.
If the diff erential temperature is higher than the preset start-up
temperature diff erential, the circulation pump will run.
To avoid unnecessary pump operation the temperature of the solar
collector has to be higher than 15°C before the pump starts operating.
The pump will run until the temperature diff erential is below 2°C.

2.0 Anwendung
T1 : Temperatursensor im Solarkollektor
T2 : Temperatursensor im Warmwasserspeicher
: Umwälzpumpe
: Solarwärmeregler
Der Regler SH-E01 wird zur Regelung in Warmwasseranlagen
mit einem Solarkollektorkreislauf und Warmwasserspeicher
eingesetzt, in denen das Warmwasser durch Solarenergie
aufgeheizt wird. Die Umwälzpumpe des Solarheizkreislaufs wird
durch die Temperaturdiff erenz zwischen dem Solarkollektor
und dem Warmwasserspeicher geregelt. Die PumpenAnlauftemperaturdiff erenz ist einstellbar. Um überfl üssigen
Pumpenbetrieb zu vermeiden, empfehlen wir die Einstellung
einer Anlauftemperaturdiff erenz von 15 K, d.h. die Pumpe läuft an,
wenn die Temperatur im Solarkollektor die Speichertemperatur
um mehr als 15 K überschreitet und wird gestoppt, wenn diese
Temperaturdiff erenz auf unter 2 K gefallen ist.
