Installation Guide4
Danfoss ECtemp Next Plus
Standard “Automatic electrical controls for household and
similar use”:
• EN/IEC 60730-1 (general)
• EN/IEC 60730-2-9 (thermostat)
1�2 Safety Instructions
Make sure the mains supply to the thermostat is turned o
before installation.
Important: When the thermostat is used to control a oor
heating element in connection with a wooden oor or
similar material, always use a oor sensor and never set the
maximum oor temperature to more than 35°C.
Please also note the following:
• The installation of the thermostat must be done by an
authorized and qualied installer according to local
regulations.
• The thermostat must be connected to a power supply
via an all-pole disconnection switch.
• Always connect the thermostat to continuous power
supply.
• Do not expose the thermostat to moisture, water, dust,
and excessive heat.
5Installation Guide
Danfoss ECtemp Next Plus
2 Mounting Instructions
Please observe the following placement guidelines:
Place the thermostat at a suitable height on the wall
(typically 80-170cm.).
The thermostat should not be placed in wet rooms.
Place it in an adjacent room and use oor sensor
only. Always place the thermostat according to local
regulation on IP classes and use oor sensor only.
Do not place the thermostat on the inner side of an
exterior wall.
Always install the thermostat at least 50 cm. from
windows and doors.
Do not place the thermostat in a way that it will be
exposed to direct sunlight.
Note: A oor sensor enables a more accurate
temperature control and is recommended in all oor
heating applications and mandatory under wooden
oors to reduce the risk of over-heating the oor.
Installation Guide6
Danfoss ECtemp Next Plus
• Place the oor sensor in a conduit in an appropriate place
where it is not exposed to sunlight or draft from door
openings.
• Equally distant and >2cm from two heating cables.
• The conduit should be ush with the oor surface -
countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm.
Connect the thermostat according to the connection
diagram.
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 oor sensor in a conduit in the
oor.
