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. Ifa the 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 (230V# 10 %, 50 Hz) is supplied to terminals 4 and 5, at that phase (L) is determined by indicator and is con- nected to terminal 5, and neutral (N)- to terminal 4. Load (connecting wires from 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, 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 16 A. To protecta people against electric shock leakage is installed the SSD (safety shutdown device). This event is obligatory when installing floor heating in wet areas. The thermostat 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 thermostat in the mounting box. To this a front frame must be removed. Put the thermostat in the mounting box and tighten the mounting screws.

The thermostat terminals are designed for a wire with 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 no more than 3 mm. A screwdriver with a blade width more than 3 mm can cause mechanical damage to the terminals. This may result in the loss of right for warranty. The terminals should be tighten with torque 0,5 N·m.

From the mounting box with thermostat the mounting tube (metal tube 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).
