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.
