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.
Digital sensor (D18) is connected to terminal 1 using white wire and to terminal 2 using blue wire. If a thermostat pass into accidental regime of work of offloading by timer (Operating Instructions page 12), try connecting to terminal 1 using blue wire and to terminal 2 using white wire. If, at both attempts, the thermostat does not see the sensor, contact the Service Center.
Power voltage (230 V ± 10 %, 50 Hz) is supplied to terminals 3 and 4, at that phase (L) is determined by indicator and is con-nected to terminal 4, and neutral (N) — to terminal 3.
The load connection wires are connected to terminal 5 and to the neutral terminal block (not included).

THE THERMOSTAT IS MOUNTED AND CONNECTED after the installation and load testing
IN THE CASE OF INCORRECT WIRING, is possible failure of the thermostat. make sure that external sensor and mains voltage are connected correctly.

INSTALLATION

The thermostat 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, swimming pool the thermostat should be installed at the 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 phase conductor, as shown in the Wiring 1. It should be designed for not more than 32 A.
To protect a people against electric shock leakage is installed the SSD (safety shutdown device). This event is obligatory when installing floor heating in wet areas.
To install the thermostat you should:

fix the thermostat on the mounting rail (DIN);
supply power, load and sensor wires;
perform the compounds according to the passport data.

The thermo stat terminals are designed for a wire with 2 section not more than 16 mm . To reduce the mechanical loads on the terminals it is desirable to use a soft wire. The wires are tightened in the power terminals with a screwdriver with a bit width of not more than 6 mm, and in the terminals for the sensor — of not more than 3 mm. A screwdriver with a bit width of more than 6 mm for power terminals (more than 3 mm for sensor terminals) can cause mechanical damage to the terminals. This may cause to the loss of the warranty. Tighten the power terminal with moment of 2.4 N·m and sensor terminal — 0.5 N·m. Poor tightening can lead to poor contact and overheating of terminals and wires, and excessive tightening to damage of terminals and wires The use of aluminum inot desirable.

From the mounting box with thermostat 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 a tape. The sensor is introduced into the pipe after solidifying of screed.
If necessary is acceptable reduction and increasing (up to 20 m) of sensor connecting wires. Near the sensor connecting wires should not be the power cables, they may be 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 data sheet, the heating cable must be connected with a contactor (magnetic starter, power relay), which is designed for this current (wiring 3).
