II. INSTALLATION MANUAL

CAUTION! Power off the thermostat and the electronic device (e g heating cable) which will be connected and the electric source before installation and maintenance. It is highly recommended that the installation procedure is processed by trained personnel.

III. SENSOR INSTALLATION

Place the sensor with cable inside the corrugated pipe (diameter not less than 16mm). Bending radius of corrugated pipe not less than 5 cm (see Figure 1).
Plug one end of corrugated pipe via waterproof cork (to prevent the water or cement grout penetration inside); place the corrugated pipe with sensor in a hole between the nearest coils of heating cable.
It is recommended to place the end of corrugated pipe with the sensor inside as much closer as possible to the upper floor layer
Place the second end of corrugated pipe near with the connection box for thermostat.

There is a possibility to lengthen the cable for sensor until 10 m

THERMOSTAT INSTALLATION

Electronic thermostat Energy is restricted to be used in indoor only.
It should be mounted on an inner wall about 1-1.5m above the floor in easy of approach place with free air circulation (see Figure 1).
The thermostat is protected from steam condensate and could be mounted in bathroom. It is not recommended to mount the thermostat near with the equipment which could shed a warm (TV, refrigerator, heater) and also in a places where it will could be exposed to direct sunshine. It is prohibited to mount the thermostat in a places where it could be exposed of dripping or splashing.

ELECTRICAL CONNECTION

CAUTION! Turn off the electric source before wiring.
1. Place into the wall the standard plastic wall socket and lead inside the electrical wires of mains electricity 230V, heating cable and temperature sensor.
The length of leads without insulation layer must be as follows:
– for wires of mains electricity and electrical wires of heating cable 6 mm.
– for wires of temperature sensor – 8mm
The ends of multicore cable used to be soldered to avoid the possibility of short circuit.
2. Fix the electrical wires of temperature sensor in spring-loaded contacts (see Figure 2) of blue color SENSOR (using the yellow clips).
The polarity of these wires is equal.
3. Fix the ends of electrical wires of heating cable in inner screw joint contacts of green color Max.Load 14A.
4. Connect the outlets of screen from heating cable with the earth conductor of three-phase electrical network using the external terminal contact (not enter into the terminal block of thermostat)
5. Fix the electrical wires of neutral cable from main electricity in a green screw joint contact N.
6. Fix the electrical wires of load cable from main electricity in a green screw joint contact L.
7. Make sure that all connection are fixed enough strong and save.

MOUNTING

Press on the catch on the top edge of the top housing using the screw and take away the front plastic frame (see Figure 3);
Unscrew the two self-tapping screw (which fasten the top hosing to the bottom hosing) and take away the display block (do not take away the self-taping screws from the display block);
Take away the middle plastic frame from the bottom housing of thermostat (do not take away the inter block insulation gasket from the housing);
Place the bottom housing in a wall socket. Make sure that the wires are easily placed inside the wall socket to be sure that they will not be wedged between wall and thermostat. Fix the thermostat by the screws;
Place the plastic frame over the bottom housing;
Holding the plastic frame, place the top housing with display over the plastic frame, make sure that left and right grooving are in the correct position to the response holes of bottom housing and fix it to the bottom housing by the two self-taping screws;
Make sure that all part of thermostats fit to each other and have no backlash;
Place the front plastic panel over the display block, make sure that all buttons are correctly placed in the exact grooving, after that, lock the front panel on the display block by the catch on the top edge.

Normal mode.
Press and hold the key for three second (see Figure 4) – the orange light turns on, display goes to the Normal mode, on the display there will be indicated:

icon
current floor temperature
the heating cable ON or OFF status:
– if the floor temperature is lower than the set value (default set temperature value is 25°C) – the icon appears, the heating cable is ON;
– if the floor temperature is higher than the set value (default set temperature value is 25°C) – the icon disappears, the heating cable is OFF.

Caution! If the floor sensor is disconnected or damaged – the symbol appears, the icon disappears, the heating cable is OFF.

Temperature setting up.

At Normal mode press – the icon and the set temperature appears (default set temperature is 25°C);
Press to increase ( decrease) the set temperature value in step 0.5°C (press and hold the key or to fast advance the set temperature value in 4Hz).

Display returns to the Normal mode when no keys are pressed in 10 seconds, the icon disappears, the icon of the current floor temperature appears.

Thermostat operates as follows:

If the floor temperature is lower than the set value (default set temperature value is 25°C) the icon appears, the heating cable is ON;
If the floor temperature is lower than 0°C – the symbol LO and icon appears, the heating cable is ON;
If the floor temperature is higher than the set value (default set temperature value is 25°C) – the icon disappears, the heating cable is OFF;
If the floor temperature is higher than 40°C – the symbol HI appears, the icon disappears, the heating cable is OFF.

After the temperature value is set for the last program the display will return to Normal mode.

Early start.
Thermostat TK03 has an additional option called Early start that operates automatically:
the first program Morning will be started earlier (but no more than 60 minutes) based on last day’s actual performance so that the floor temperature should be reached the set temperature at the scheduled time.

Manual Override mode.
The Manual Override mode is using to override the program set temperature value temporary, it will be released until the next program:
