ECtemp Next Plus HW

1 Introduction

ECtemp Next Plus HW is an electronic programmable timer thermostat used for controlling domestic hot water temperature. The thermostat is designed for ﬁxed installation only and can be used for both temperature maintenance and legionella mitigation (above 55 °C), using timer and external sensor features.

• Correct wiring is essential. Use instrument to conﬁrm L and N before wiring is recommended.

• Don’t remove too much of the insulation cover from the wire to avoid short circuit, caused by the naked wire touching the metal 86 mm. sized mounting wall box.

• Don’t let the screw press or touch the wire when using screw to ﬁx room thermostat in wall box. A short-circuit risk exists if the wire insulation cover is damaged by the screw, and if the naked wire connects with the screw.

• If walls must be painted, mount the room thermostat after painting, to avoid dust or paint material penetrating the room thermostat and thus damaging the PCB.

• The max load of relay is <16 A (resistive) or <6 A (inductive). The relay will be damaged if the load exceeds the limit.

• Don’t cover the thermostat, for instance by hanging towels directly in front of it.

Should you, against all expectations, experience a problem with your Danfoss product, you will ﬁnd that Danfoss oﬀers a 5 year warranty from the date of purchase on the following conditions:

During the warranty period Danfoss shall oﬀer a new comparable product or repair the product in case the product is found to be faulty by reason of defective design, materials or workmanship. Repair or replacement shall be carried out solely at Danfoss’s discretion. Danfoss shall not be liable for any consequential or incidental damages including, but not limited to,

ECtemp Next Plus HW

1 Einführung

Der ECtemp Next Plus HW ist ein elektronischer, programmierbarer Timer-Thermostat zur Regelung der Trink warmwassertemperatur. Der Thermostat ist ausschließlich für eine feste Installation ausgelegt und kann sowohl für die Temperaturerhaltung als auch für die Legionellenreduzierung (über 55 °C) verwendet werden, wobei Timer und externe Fühlerfunktionen verwendet werden.

• Eine ordnungsgemäße Verdrahtung ist unerlässlich. Es emp-

ﬁehlt sich, L und N vor der Verdrahtung mit einem Messgerät zu überprüfen.

• Nicht zu viel von der Isolierung des Drahts entfernen, da der Kon-

takt zwischen dem nicht isolierten Draht und dem metallischen Wandkästchen (Größe 86 mm) zu einem Kurzschluss führen kann.

• Bei der Verwendung von Schrauben zur Befestigung des

Raumthermostats im Wandkästchen darf die Schraube den Draht nicht berühren oder auf den Draht drücken. Wird die Isolierung des Drahts durch die Schraube beschädigt, kann bei Kontakt zwischen nicht isoliertem Draht und Schraube ein Kurzschluss ausgelöst werden.

• Muss die Wand gestrichen werden, ist der Raumthermostat erst

nach dem Streichen einzubauen, da sonst Staubpartikel oder Farbmaterial den Raumthermostat durchdringen und so die Leiterplatte beschädigen können.

• Die maximale Last für die Relaisausgänge beträgt <16 A (ohmsch)

bzw. <6 A (induktiv). Bei einer Überschreitung dieser Grenze wird das Relais beschädigt.

• Den Thermostat nicht abdecken, z. B. durch Handtücher, die

direkt vor dem Thermostat aufgehängt werden.
