Danfoss ECtemp Next Plus Electronic Intelligent Timer Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Installation guide for Danfoss ECtemp Next Plus electronic intelligent timer thermostat.
• Page 2: Introduction Technical specifications Safety instructions Mounting instructions Symbols Settings Power ON/OFF Initial settings Advanced programmable timer Error codes
• Page 3: Danfoss ECtemp Next Plus is an electronic programmable timer thermostat for controlling electrical floor heating elements. The thermostat is designed for fixed installation and can be used for direct heating of the entire room or for comfort heating of the floor. Operation voltage ranges from 85-250V~, 50/60 Hz with a standby power consumption of 0.4 W. The relay supports a resistive load of max. 16 A / 3680 W @ 230 V and an inductive load of max. 1 A. The floor sensor is an NTC 15 kΩ at 25°C with specific sensing values at different temperatures. Control hysteresis is set at 1.0°C. The ambient temperature range is from -10°C to +60°C. Frost protection temperature is adjustable between 5°C to 9°C, with a default setting of 5°C.
• Page 4: Danfoss ECtemp Next Plus Temperature range: Room temperature: 5-35°C; Floor temperature: Max. 35°C. Sensor failure monitoring: The thermostat has a built-in monitoring circuit, which will switch off the heating if the sensor is disconnected or short-circuited. Cable specification max: 1x4 mm² or 2x2.5 mm². Ball pressure test temperature: 75°C. Pollution degree: 2 (domestic use). Storage temperature: -20°C to +65°C. Protection class: Class II. Dimensions: 86 x 86 x 16/40.5 mm (in-wall depth: 24.5 mm). Weight: 103 g. Electrical safety and Electro-Magnetic Compatibility for this product is covered by the compliance with the EN/IEC Standard “Automatic electrical controls for household and similar use”: EN/IEC 60730-1 (general).
• Page 5: Danfoss ECtemp Next Plus Safety instructions Make sure the mains supply to the thermostat is turned off before installation. 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. 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. Always connect the thermostat to continuous power supply. Do not expose the thermostat to moisture, water, dust, and excessive heat. Mounting instructions Please observe the following placement guidelines: Place the thermostat at a suitable height on the wall (typically 80-170cm).
• Page 6: Danfoss ECtemp Next Plus The thermostat should not be placed in wet rooms. 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. A floor sensor enables a more accurate temperature control and is recommended in all floor heating applications. Place the floor sensor in a conduit in an appropriate place where it is not exposed to sunlight or draft from door openings. The conduit should be flush with the floor surface - countersink the conduit if necessary. Route the conduit to the connection box.
• Page 7: 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. Always install the floor sensor in a conduit in the floor. The following symbols appear in the display: Room temperature, Away mode, Floor temperature, Child safety lock, Power ON/OFF, Temperature indication. Installation Guide

• Page 9: Danfoss ECtemp Next Plus Initial settings must be specified when the unit is activated for the first time. Press M button for 6 seconds to enter the parameter setting mode. The upper digits indicate the parameter number. Press M for parameter selection. Press < or > to set the parameter range. Complete all adjustments. Press to exit ECtemp Next Plus settings. To exit ECtemp Next settings, automatic wait approx. 30 seconds. The digits indicate the set value as follows: Parameter settings include working mode and temperature control modes.
• Page 10: Danfoss ECtemp Next Plus Maximum floor temperature 20-30˚C (only for 01 in P02). Frost protection options: Enable (01) or Disable (02) at 5-9˚C. Frost protection setpoint is 5˚C. Timer display option can be set to 24h (01) or 12h (02). Room temperature display option at shutdown: No display (01) or Display current temp. (02). Using only a room sensor is not recommended due to the risk of overheating the floor. Advanced Programmable Timer mode allows for a timer-controlled program for automatic comfort temperature. The function consists of two programs: P1 with 4 events in 5 days and P2 with 4 events in 2 days. Installation Guide.
• Page 11: Danfoss ECtemp Next Plus The display shows Sa. Su. Press and hold to display Mo. Tu. We. Th. Fr. Use < or > to select the start time. Press to accept the setting. Use < or > to select the temperature. Repeat the Event 1 procedure for programming Event 2-4. The thermostat will continue the 4-event program based on the present time and day. To set and change the room temperature temporarily, press < or > to change the desired temperature value. When releasing the < or >, the display returns to showing the actual temperature. A default program provides timer control if the customer does not create own programs.
• Page 12: Danfoss ECtemp Next Plus Changing of desired temperature - press < or >. SET is showed in the display. Adjustment is changed in steps of 0.5°C. When releasing < or > again the display returns to normal mode and shows actual temperature. It will be possible to set the maximum floor temperature up to 45°C. It would also be possible to use only one temperature sensor. This option is not recommendable as this causes an increased risk of overheating of the floor. Extending maximum floor temperature and setting into room only mode – See point 4.9 and 4.10. IMPORTANT: When the thermostat is used to control a floor heating element in connection with a wooden floor.
• Page 13: Danfoss ECtemp Next Plus Always use a floor sensor and never set the maximum floor temperature to more than 35 °C. Approximate setting for 25˚C floor temperature varies by flooring type. Examples of flooring include 8 mm HDF based laminate, 14 mm beech, and 22 mm solid oak plank. Max carpet thickness suitable for floor heating is according to EN 1307. To adjust time and weekday, press the appropriate buttons. Use < or > to adjust hours and minutes.
• Page 14: Danfoss ECtemp Next Plus Press again to shift to weekdays and use < or > for selecting right day. Finish timer setting by pressing any other button or wait for automatic exit after 6 sec. without operation. Press M and > simultaneously to enable safety lock. To release safety lock press M and > simultaneously again. Press M to get into Away mode. Changing the desired temperature in Away mode is done by pressing < or >. Adjustment in steps of 0.5°C. Press M to exit Away mode again. Press M and hold – Press < within 6 sec to display current floor temperature.
