1 Introduction

ECtemp 330 is an electronic thermostat to be installed in

electric cabinets with DIN rail attachment. The thermostat

must be installed via an all-pole disconnection switch. Ei-

ther a ﬂoor sensor or an external room sensor must be used

to measure and control the desired temperature.

The thermostat has a button to adjust the temperature

setting with a scale from +5 to +45°C. An LED indicator

shows standby periods (green light) and heating periods

(red light).

1.2 Safety Instructions

Make sure the mains supply to the thermostat is turned oﬀ

before installation.

IMPORTANT: When the thermostat is used to control a

ﬂoor heating element in connection with a wooden ﬂoor or

similar material, always use a ﬂoor sensor and never set the

maximum ﬂoor temperature to more than 35°C.

Please also note the following:

• The installation of the thermostat must be done by an

authorized and qualiﬁed installer according to local

regulations.

• The thermostat must be connected to a power supply

via an all-pole disconnection switch.

• The sensor is to be considered as live voltage. Have

this in mind if the sensor must be extended.

7Installation Guide

The screen of the heating cable must be connected

to the earth conductor of the power supply cable by

using a separate connector.

Note: Always install the ﬂoor sensor in a conduit in

the ﬂoor.

3. Turn on the power supply.

3 Settings

If a ﬂoor sensor is used, please be aware of the following:

• The ﬂoor temperature is measured where the sensor

is placed.

• The temperature of the bottom of a wooden ﬂoor can

be up to 10 degrees higher than the top.

Installation Guide8

• Floor manufactures often specify the max tempera-

ture on the top surface of the ﬂoor (usually 27-28˚C).

• Always use a ﬂoor sensor to control ﬂoor heating.

Without a ﬂoor sensor, the temperature control may

be less accurate and you risk overheating the ﬂoor.
