1.0 Installation Overview
2.0 System Overview
Please Note:
This product should only be installed by a qualified electrician or
competent heating installer and should be in accordance with the
current edition of the IEEE wiring regulations.
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 differential
temperature between the solar collector and the tank bottom.
If the differential temperature is higher than the preset start-up
temperature differential, 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 differential is below 2°C.

Fit the temperature sensors in the immersion pockets - in the solar
collector and at the bottom of the hot-water tank. The cables are 3 m,
but can be extended as required by 2 x 0.75 mm2double-insulated
cable. EMC approved for 50 m cable length.
4.0 Operation
4.1 Function Test
The regulator is ready for operation when connected the mains. The
display becomes active and current temperatures are shown.
Display updates once per minute. Pressing the INFO button causes
the display to update immediately.

1.0 Installationsanweisung
Bitte beachten Sie:
Dieses Produkt darf nur von einem qualifizierten Elektriker oder
Heizungsinstallateur gemäß der aktuellen Version der IEEE
Verkabelungsvorschriften installiert werden.
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 Temperaturdifferenz zwischen dem Solarkollektor
und dem Warmwasserspeicher geregelt. Die Pumpen-
Anlauftemperaturdifferenz ist einstellbar. Um überflüssigen
Pumpenbetrieb zu vermeiden, empfehlen wir die Einstellung
einer Anlauftemperaturdifferenz 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
Temperaturdifferenz auf unter 2 K gefallen ist.
