1 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:
- A touchscreen display with light.
- An easy-to-follow menu-driven programming and operation.
- An installation wizard with room/floor type-specific setup (requires an app).
- Support for multiple frame systems.
- Compatible with several 3rd party NTC sensors.
- Thermostat settings can be specified before installation and imported to the thermostat using a web-generated code, or copied from a thermostat in a similar installation.
- Smart access to thermostat settings after installation by using a web code interface, for easy setup or remote troubleshooting.
Regarding Connectivity:
- 10 smart devices (like Smartphone or Tablet) can be connected to 1 thermostat.
- 2 smart devices can be in contact with the thermostat at the same time.

3 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.
Please also note the following:
- 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 or lack of experience and knowledge, if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved, by a person responsible for their safety.
- 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.
4 Mounting Instructions
Please observe the following placement guidelines:
[Thermostat on wall icon] Place the thermostat at a suitable height on the wall (typically 80-170 cm.).
[Wet room icon] The thermostat should not be placed in wet rooms. Thermostat must be placed outside zone 2. Place it in an adjacent room and use floor sensor only. Always place the thermostat according to local regulation on IP classes.
[Interior wall icon] Do not place the thermostat on the inner side of a poorly insulated exterior wall.
[Window/door icon] Always install the thermostat at least 50 cm from windows and doors, due to draft, when using regulation in: floor and room mode or room alone mode.
[Sun icon] Do not place the thermostat in a way that it will be exposed to direct sunlight.
Note: A floor sensor is recommended in all floor heating applications and mandatory to 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 >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 min 50 mm.
[Conduit installation diagram] Showing conduit installation with minimum bending radius of 50 mm and flush mounting.
Follow the steps below to mount the thermostat:
- Unpack 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.
[Connection diagram] Showing NTC sensor, L, N, and earth connections, mains power, and load output.
Note: 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 of top part to the snap locks/bottom part.
- Click the front part module in place. Pay attention, in relation to the female header, in not to bending the connectors. Press carefully until the frame is fixed against the rubber gasket.
When mounting and reassembling the thermostat.
Important: Do NOT press in the center of the display screen.
[Thermostat release diagram] 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.

7 Settings
IMPORTANT DURING SET-UP
Select whether only a floor sensor or a combination of room and floor sensor should be used. A "room only" option is also available, but requires that you have to break the small plastic seal on the back of the display module, e.g. using a screwdriver; it will be possible to set the maximum floor temperature up to 45 °C. Furthermore, it will be possible to use only a room sensor. However, this option is not recommendable due to an increased risk of overheating the floor.
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.
Note: Please contact the floor supplier before changing the maximum floor temperature and be aware of the following:
- The floor temperature is measured there, 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 manufactures often specify the max. temperature on the top surface of the floor.
