WIRING

Thermostat supports two types of sensors: analog sensor (thermal resistor) or digital sensor (DS18B20). Analog sensor R10 is connected to terminals 1 and 2. Wires’ colors are of no importance. The digital sensor is connected to terminal 1 using white wire and to terminal 2 using blue wire. If a thermo passes into the accidental regime of work of offloading by timer (D18) stat (Operating Instructions page ), try connecting to terminal 1 using blue wire and to the terminal using white wire. If, at both attempts, the thermo does not see the sensor, contact the Service CenterPower voltage (230 V ± 10 %, 50 Hz) is supplied to terminals 4 and 5, at that phase (L), is determined by indicator and is connected to terminal 5, and neutral (N) — to terminal 4. Load (connecting wires from the heating element) is connected to terminals 3 and 6. THE STAT IS MOUNTED AND CONNECTED after the installation and load testing THERMO IN THE CASE OF INCORRECT WIRING, which is the possible failure of the thermostat. make sure that the external sensor and mains voltage are connected correctly.

INSTALLATION

The stat is designed for indoor installation. The ingress risk of moisture or liquid into the place of installation must be minimized. When installed in a bathroom, toilet, kitchen, or swimming pool the stat should be installed at a place out of reach of casual spraying. The ambient temperature during installation must be between –5 … +45 °C. The installation height of the thermostat should be in the range 0,4…1,7 m above the floor level. To protect against short-circuit in the load circuit the circuit breaker (CB) has to be installed before installing the thermostat. The circuit breaker is installed in the gap of the phase conductor, as shown in the Wiring. It should be designed for not more than 16 A. To protect people against electric shock leakage is installed the SSD (safety shutdown device). This event is obligatory when installing floor heating in wet areas. The stat is mounted in the standard mounting box 60 mm in diameter, with mounting screws. For installation, you must:

• make a hole in the wall for box mounting and wall chase for power wires and the sensor;
• take the power wires of the heating system and the sensor to the mounting box;
• perform the compounds according to the passport data
• fix the thermo in the mounting box. To this, a front frame must be removed.
• Put the thermo in the mounting box and tighten the mounting screws.

The stat terminals are designed for a wire with a section not more than 2.5 mm. To reduce the mechanical loads on the terminals it is desirable to use a soft wire. The ends of the wires must be cleaned and crimped with ferrules with insulation. The wires are tightened in the terminals using a screwdriver with a blade width of no more than 3 mm. A screwdriver with a blade width of more than 3 mm can cause mechanical damage to the terminals. This may result in the loss of the right to warranty. The terminals should be tightened with torque 0,5 N·m. From the mounting box with the stat, the mounting tube (metal tube Ø 16 mm) is put into a zone heated by about 0 5 m. The curves and the length of the tube should ensure smooth movement of the sensor. The end of the pipe introduced into the zone, which is heated, must be carefully sealed to avoid ingress of the solution, for example, with tape. The sensor is introduced into the pipe after solidifying the screed.

If necessary is the acceptable reduction and increase (up to 20 m) of sensor connecting wires? Near the sensor connecting wires should not be the power cables, they maybe interfere. It is necessary that the thermostat commutes the current not more than 2/3 of the maximum power specified in the passport. If the exceeds 2/3 of the maximum current specified in the datasheet, the heating cable must be connected with a contactor (magnetic starter, power relay), which is designed for this current (wiring 3).
