Danfoss ECtemp Next Plus
The thermostat should not be placed in wet rooms. Place it in an adjacent room and use floor sensor only. Always place the thermostat according to local regulation on IP classes and use floor 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 floor sensor enables a more accurate temperature control and is recommended in all floor heating applications and mandatory under wooden floors to reduce the risk of over-heating the floor. · Place the floor 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 flush with the floor surface countersink the conduit if necessary.
· Route the conduit to the connection box.

Installation Guide

Danfoss ECtemp Next Plus
· 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 floor sensor in a conduit in the floor.

43 Advanced Programmable Timer

The Advanced Programmable Timer mode enables the setting of a timer-controlled program for automatic comfort temperature, and an energy-saving lower setback temperature if standard room comfort temperature is not required.

The function consists of 2 programs:

P1 with 4 events in 5 days (Mon. Tue. Wed. Thu. Fri.)

P2 with 4 events in 2 days (Sat. Sun.).
