Product Information

Smart Control of Heating

• The Smart Control of Heating is a thermostat designed for indoor installation that allows you to control an electric heating cable or heating film and water floor system with a normally closed electrothermal actuator. The supply package includes a thermostat, frame, temperature sensor with connected wire, technical data sheet, installation, and operation manual, and warranty card.
• The thermostat has an adjustment range, maximum load current, rated load capacity, input voltage, and weight in the complete set. The basic mounting dimensions are also provided, along with the length of the sensor-connected cable, number combinations under heat and without heating, temperature hysteresis, and degree of protection GOST14254.
• Before installation and operation of the device, it is important to read the installation and operating instructions to avoid possible danger, mistakes, and misunderstandings.

Product Usage Instructions

1. Ensure that the external sensor and mains voltage are connected correctly after installation. Incorrect wiring may cause the failure of the thermostat.
2. The thermostat is designed for indoor installation. When installed in a bathroom, toilet, kitchen, or swimming pool, it should be installed at a place out of reach of casual spraying. The installation height of the thermostat should be in the range of 0.4…1.7 m above the floor level.
3. The thermostat is mounted and connected after the installation and load testing. 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. It should be designed for not more than 16 A.
4. To protect against electric shock leakage, the SSD (safety shutdown device) is installed. This event is obligatory when installing floor heating in wet areas. For working SSD, the heating cable screen must be grounded (connected to the protective conductor PE) or, if there is a two-wire network, it is necessary to make protective neutral earthing. That is to connect the screen to a zero before SSD.
5. The thermostat is mounted in the standard mounting box 60 mm in diameter, with mounting screws.
6. The sensor is introduced into the pipe after solidifying the screed. If necessary, it is acceptable to reduce and increase (up to 20 m) sensor connecting wires. To increase the length, it is unacceptable to use two conductors of a multi-wire cable that is used to power the heater. The best solution would be a separate cable to the sensor, mounted in a separate tube. Near the sensor connecting wires should not be the power cables, they may interfere.

The thermostat turned RTP is designed to maintain a constant temperature of 10…40 °C in underfloor heating systems based on:

1. Electric heating cable or heating film.
2. Water floor system with a normally closed electrothermal actuator, operating voltage 230 V.

• The temperature is controlled at that point where there is a temperature sensor. The sensor supplied as part of the package is designed to be placed in the mounting tube (reinforced-plastic pipe Ø 16 mm). The pipe is located in the sand cement screed. If necessary the sensor should be easily drawn out of the mounting tube.

TECHNICAL DATA

WIRING

• Without a sensor, the thermostat will not work.
• The temperature sensor is connected to terminals 1 and 2.
• The supply voltage (230 V ± 10%, 50 Hz) is applied to terminals 5 and 6, and the phase (L) is determined by the indicator and is connected to terminal 6, a zero (N) —on terminal 5.
• To terminals 3 and 4 is connected the load (the connecting wires from the heating element).
• THE STAT IS MOUNTED AND CONNECTED after the installation and load testing THERMO
• IN THE CASE OF INCORRECT WIRING, is a possible failure of the thermostat. make sure that the external sensor and mains voltage are connected correctly.

INSTALLATION

• After installation make sure that external sensor and mains voltage are connected correctly. In the case of incorrect wiring, is possible failure of the thermostat.
• 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. range 0,4…1,7 m above the floor level.
• The thermostat is mounted and connected after the installation and load testing.
• 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 2. It should be designed for not more than 16 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. For working of SSD the heating cable screen must be grounded (connected to the protective conductor PE) or, if there is two-wire network, it is necessary to make protective neutral earthing. That is to connect the screen to a zero before SSD. In Wiring 2 protective neutral earthing is shown with dotted line.
• 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 by slipping it from the side with a screwdriver inserted into the slot (Fig.1). Put the thermostat in the mounting box and tighten the mounting screws.
• The thermostat terminals are designed for a wire with 2 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. The 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.
• The couplings with heating wire are poured in the screed. Mounting of the sensor must be performed so that it was possible to easily replace it. 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. To increase the length is unacceptable to use two conductors of a multi-wire cable that is used to power the heater. The best solution would be a separate cable to the sensor, mounted in a separate tube. Near the sensor connecting wires should not be the power cables, they may be interfere.
• If you purchased a heating cable and its labeling hasn’t its rated power, then before connecting the thermostat (to avoid breakdown of the thermostat due to the excess of its certified values) power (P) must to be calculated.
• For this to measure the current (I) consumed of the heating cable (using the ammeter with corresponding measurement limit) and multiply by the supply voltage (U). Or to measure the resistance of the heating cable (R) with ohmmeter, divide the mains voltage (U) to the obtained resistance and multiply by the main voltage (U).
• P = U × I (V) P = U × (U / R) (V)
