Summary of Contents

• Page 1: Installation guide for Danfoss ECtemp Smart. Intelligent electronic timer thermostat with Wi-Fi connectivity and app control.
• Page 2: Introduction ECtemp™ Smart is an electronic programmable timer thermostat used for controlling electrical floor heating elements. The thermostat is designed for fixed installation only and can be used for both direct heating of the entire room and for comfort heating of the floor. Among others, the thermostat has the following features: Installation Guide
• Page 3: Danfoss ECtemp™ Smart features a touchscreen display with light and an easy-to-follow menu-driven programming and operation. It includes an installation wizard with room/floor type-specific setup, which requires an app. The system supports multiple frame systems and is compatible with several third-party NTC sensors. Thermostat settings can be specified before installation and imported using a web-generated code or copied from a similar installation. Smart access to thermostat settings is available after installation through a web code interface for easy setup or remote troubleshooting. Up to 10 smart devices, such as smartphones or tablets, can be connected to one thermostat. Two smart devices can be in contact with the thermostat simultaneously. The ECtemp™ Smart requires working Wi-Fi to function.

• Page 5: Danfoss ECtemp™ Smart Ambient temperature: 0 ° to +30 °C Frost protection temperature: 5 °C to +9 °C (default 5 °C) Temperature range: Room temperature: 5-35 °C; Floor temperature: 5-45 °C Max. floor temperature: 20-35 °C (if unrecovable seal is broken then up to 45 °C) Min. floor temperature: 10-35 °C, only with combination of room and floor sensor 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 Ball pressure test temperature: 75 °C Pollution degree: 2 (domestic use) Storage temperature: -20 °C to +65 °C Protection class: Class II
• Page 6: Danfoss ECtemp™ Smart Dimensions: 85 x 85 x 20-24 mm (in-wall depth: 22 mm) Weight: 127 g Electrical safety and Electro-Magnetic Compatibility for this product is covered by compliance with the EN/IEC Standard “Automatic electrical controls for household and similar use.” 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. Installation Guide
• Page 7: Danfoss ECtemp™ Smart 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. This thermostat can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities if they have been given supervision or instruction concerning use of the appliance in a safe way. Children should be supervised to ensure that they do not play with the thermostat. Cleaning and user maintenance shall not be made by children without supervision.
• Page 8: Danfoss ECtemp™ Smart Mounting instructions Please observe the following placement guidelines: Place the thermostat at a suitable height on the wall (typically 80-170 cm). The thermostat should not be placed in wet rooms. Thermostat must be placed outside zone 2. Always place the thermostat according to local regulation on IP classes. Do not place the thermostat on the inner side of a poorly insulated exterior wall. Always install the thermostat at least 50 cm from windows and doors, due to draft. Do not place the thermostat in a way that it will be exposed to direct sunlight.
• Page 9: Danfoss ECtemp™ Smart A floor sensor is recommended in all floor heating applications and mandatory for thin mats under wooden floors to reduce the risk of overheating the floor. Place the floor sensor in a protecting plastic conduit in the floor construction in an appropriate place, where the floor is not exposed to sunlight or draft from door openings. Equally distant and more than 2 cm from the heating cables on both sides. The conduit should be flush with the floor surface; countersink the conduit if necessary and possible. Route the conduit to the connection box. The bending radius of the conduit must be a minimum of 50 mm.
• Page 10: Danfoss ECtemp™ Smart Follow the steps below to mount the thermostat. Unpack the thermostat. 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. Fasten the thermostat firmly to a flush mounted wall box or an exterior wall box by driving the screws through the holes in each side of the thermostat. Add the frame before assembling the top part to the snap locks/bottom part. Click the front part module in place.
• Page 11: Danfoss ECtemp™ Smart Important: Do NOT press in the center of the display screen. When mounting and reassembling the thermostat. Press your fingers under the side of the front part and pull toward you until it releases from the snap lock. To ensure that the batteries are fully charged, the thermostat shall be connected to main supply for minimum 15 hours. The current time and day is kept for 24 hours if mains supply is off. All other settings are stored permanently.
• Page 12: Danfoss ECtemp™ Smart Display symbols The top part main functionalities are to support user interface through display and hold all the controller logic. Display main functionalities are to show the current status of the thermostat and recognize the user actions from the buttons. Display consists of different buttons, numbers, and symbols.

• Page 16: Danfoss ECtemp™ Smart Error types and descriptions include connection to sensor lost, sensor disconnected, sensor short-circuited, and thermostat overheated. The thermostat requires a restart to operate again in case of certain errors. Contact service for issues related to sensor disconnection or short-circuiting. The thermostat will start heating when the temperature is lowered after overheating. An unrecoverable error indicates that the room temperature sensor value is too high or too low. Installation guide is provided for further assistance.

• Page 18: Danfoss ECtemp™ Smart Configuring Download the Danfoss Smart™ App from App Store or Google Play. Find WiFi name and password for the WiFi network. Identify your floor sensor type (in kOhm). Identify your installed heating output (in W). Power on the thermostat, and it will show “-” in the display. Open the Danfoss Smart™ App and follow the instructions. The Danfoss ECtemp™ Smart shows “–” indicating that power is ON, but still needs to be configured. Installation Guide
• Page 19: Danfoss ECtemp™ Smart Select whether only a floor sensor or a combination of room and floor sensor should be used. A room only option is available but requires breaking the small plastic seal on the back of the display module. It will be possible to set the maximum floor temperature up to 45°. Using only a room sensor is not recommendable due to an increased risk of overheating the floor. Installation Guide
• Page 20: Danfoss ECtemp™ Smart 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 contact the floor supplier before changing the maximum floor temperature. The floor temperature is measured where the sensor is placed. The temperature of the bottom of a wooden floor can be up to 10˚C higher than the top. Floor manufacturers often specify the max. temperature on the top surface of the floor.
