General information

The ECdry floor heating system consists of a foam/carpet heating element with heating mats inside. The system must al ways be con-trolled with a ECtemp, as it is an important part of the safety and overheating protec tions system.
The ECdry floor heating system can be used under wooden floors such as parquet and laminate. Please check the specifications with your supplier of these products.

ECdry has been tested and approved with ooring materials with insulation values from 0,07 to 0,18 m² K/W.
For best performance of the floor heating sys-tem, keep the insulation value from the ECdry heating unit to floor surface as low as possible.

The ECdry floor heating system has been developed to the dry application area for underfloor heating.
It is applicable for wooden and concrete oor constructions with the two output ranges 55 W/m² and 100 W/m².

The maximum thermal resistance be-tween the ECdry element and the room is 0,18 m² K/W as shown in the table below.

The ECdry floor heating system is for indoor ap-plications in dry rooms only. As with any other underfloor heating system, it will be most effective if the underfloor is well insulated.
The following directions will guide you step-by-step through the installation process. Please read the directions and the safety precautions before you start the installation process.

Danfoss declares that ECdry is tested according to the standard

EN/IEC 60335-2-96. Household and similar electrical appliances. Safety. Part 2-96. Particular requirements for flexible sheet heating mats for room heating.

Designing the layout

Draw a floor plan of the room and determine the most logical location for the control system and the position of the floor heating mats. Consider the placement of the thermostat to get the most convenient access and make sure the necessary power supply is available.

The output cord from the control system will go into the right side of the heating element, so you should start laying the first heat element on the right side of the floor and work towards the left side. Remember to keep
at least 70 mm of free space between the skirting/wall and the first heating element for the plug-in connection between the floor heating element and the control system. Use the filler material to fill this space afterwards.
Examples of calculations are provided below to help you work out how many ECdry floor heating mats are required. All ECdry floor heating mats are one metre wide and the standard length varies from one to five me-tres. Reduce the length of the elements to the required size as shown in the table.

Example 1: When the area is 5 m wide and 6 m long, you will need 5 × 5 m ECdry floor heating mats, plus 5 square metres of filler material.

Example 2: When the area is 3.75 m wide and 7.10 m long, you will need 6 × 4 m ECdry floor heating mats. Cut the 4 m long elements down to 3.75 m. You will also need 0.38 square metres (buy 1 square metre) of filler material. A ECdry floor heating extension cord is available as an accessory. Use the cord in the event that you are unable to make a direct connection between two adjacent floor heating elements or between the 1st mat and thermostat kit. The extension cords must only be placed in the filler material and not on top of the heating ele-ment. The extension cords can be extended with each other if necessary (if you need 3 m extension cords you can use 2 m + 1 m extension cords).

Example 3: When placing the elements after each other you should always cut away the cold end (25 cm) of the element to avoid cold zones.

Installing Supply Cord or Extension Cords:
The cords must only be placed in the filler material and not over/in the heating element.
The filler material shall be cut so it envelopes the cords. The ECdry X can withstand maxi-mum 10 A.

1 m wide filler materials without heating (1, 2 and 4 m)

Make sure that no hot spots develop when using the floor heating system. Avoid hot spots by ensuring that the heat from the floor heating is homogeneously released to the area you wish to heat and that there is free space (ventilation) under the furniture.
When designing the layout, make sure not to install ECdry heating element under permanent or built-in cupboards or fire places/ovens. ECdry have to be separated from other heat sources such as chimneys. Instead ECdry filler material should be used.

Preparing the base
Before you start installing the product, please ensure that the floor is:

• Permanently inflexible
• Dry
• Flat and regular
• Dust- and fat-free
• Free from any sharp objects

Use a powerful vacuum cleaner to remove all dust from the floor.

Remember to install a 0,20 mm vapour barrier on the subfloor before rolling out the heating mats.

Calculating current limitations
The ECdry floor heating system should be connected in accordance with national standards and wiring rules.
Maximum current per ECdry system is 10 Ampere.

In the following tables you will find maxi-mum heated surface per ECdry Touch Kit and an overview of the total power output of the systems.

Connecting the ECdry elements

Bulges on the element may occur, but will disappear when the ECdry system is heated.

All elements are equipped with an end stop to insulate the connector and protect the connection against moisture. Remove the end stops with the special tool, just before making the connection with the next heat-ing mats. If all end stops are taken out at once, remember to leave the end stop in the last element.

Connect the plug-in connection of the second element into the plug-in connection of the first element. Put the male and female connector together by hand before using the connector tool to push the elements tight together. Check that the plug-in connection fits correctly and permanently. Continue with the subsequent elements in the same manner.

Make sure that all plug-in connections fit straight and without any mechanical stress. Discontinue the floor heating installation process in the event of damage to one or more components. Incorrect installation may cause problems and/or defects to the floor heating mats. Please take precautions not to drop sharp objects on the heating mats.

Use the enclosed aluminum tape to fix mats to each other in order to secure connections and to avoid movement of mats. Place aluminum tape in two positions: directly on connections (between mat connections and in the opposite end of the mat). In addition fix 1st mat connection and output cord from ECdry Touch Kit.
Make sure that the end stop in the last element is in place before the floor covering is laid. Keep the end stops if you intend to remove/reposition your floor heating system later.

Cutting the ECdry floor heating element to size
Each end of the ECdry heating element consists of 25 cm without electrical parts inside. The ECdry heating element may only be cut at the far ends where there are no electrical parts inside as marked on the product below.
Markings and symbols have been printed on the ECdry heating mats:

To cut the element to size:
Carefully measure the piece you wish to cut ff and simply cut with a sharp knife.

Filling up the remaining space

At this point all connections between the elements should be aligned and connected and as much of the floor as possible should be covered with ECdry elements. The space without ECdry heating mats should be covered with the ECdry Filler Material to ensure an even and homogenous floor surface.
A knife, a lineal (to cut along) and a wooden plate (behind the ECdry element) can be used when cutting the ECdry Filler Material to avoid cutting into the electrical parts and ensuring a straight cut.

To be certain that the distribution of the floor heating mats in your room is correct, we suggest you make everything fit before you secure the elements permanently. It is most important to make sure that all plug-in connections are perfectly aligned to allow the flow of electricity from one element to the next. Put the floor heating mats plus any filler materials down as shown in the layout. Once you have correctly positioned all floor heating mats and you have cut the filler material to size, you can proceed with the permanent installation as explained in the following steps.

Fit the output cord
Cut a piece of material from the filler material to embed the output cord between the ECdry Controller and the ECdry heating mat.

Mounting the ECtemp Thermostat

The electrical installation must be done by an authorised electrician. Mount the ECtemp thermostat to the wall. The ECtemp should be installed in accordance with the instruction manual supplied with the thermostat and the ECdry Touch Kit.
Cut a piece of material from the filler material to make room for the ECdry Supply Cord between the ECtemp thermostat and the ECdry Touch element.
Make sure not to fold and/or squeeze the cord between the thermostat and the floor heating element but make room for the cord in the filler material. Minimum bending diameter is 5 cm.

To place the sensor in the right spot, remove the cut-away area in the ECdry Touch heating element and place the sensor down into the groove.
Fix the sensor to the heating mat with the enclosed aluminium tape.

Checking the ECdry floor heating system

Check that all work has been carried out in accordance with directions before testing the ECdry floor heating system. Testing may commence when everything has been correctly connected. Read the directions for the control system before you proceed. Set the temperature at maximum 35 °C. After a short while you will notice the ECdry floor heating mats are warming up.

If the floor heating mats are not warming up to the same temperature, the plug-in connections should be checked once again. Remember to switch off the ECdry system before checking.

Laying the top floor
Please consult the floor manufacturer to ensure that the floor covering is suitable for floor heating. The final floor covering (laminate or parquet) can be laid when the ECdry heating system has been tested.

According to ISO 13732-2, the comfortable floor surface temperature depends on the flooring material.| Soft wood (pine)

22.5 – 28°C

---|---

| Hard wood (oak)

24.5 – 28°C

However, observe the maximum floor surface temperature according to the flooring manufacturer. For most wooden floor products, the temperature is usually around 27 °C. All temperature settings must be set some degrees higher to compensate for the heat resistance in the top flooring.

Thermal resistance [m²K/W]| Examples of Flooring| Details| Approximate setting for 25°C floor temperature
---|---|---|---
0,07| 11 mm HDF based laminate| > 800 kg/m³| 28°C
0,10| 14 mm beech parquet| 650 – 800 kg/m³| 31°C
0,13| 22 mm solid oak plank| > 800 kg/m³| 32°C
0.18| 22 mm solid fir planks| 450 – 650 kg/m³| 35°C
