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 qualied 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.
