• Frost protection function when the air temperature drops below 5°C.

  (When the thermostat is off, when the room temperature drops below+5C °, the heating relay automatically turns on and turns off when the air temperature reaches+10C °).

• • Floor overheating protection - shutdown when the floor temperature exceeds 45°C.

• Saving settings after disconnecting the network.

• Resumption of the operating mode after a temporary power outage with the saved control parameters.

  __________

* In the case of a complete set with an external temperature sensor.

2. PREPARATION FOR WORK

ATTENTION! TO PREVENT ELECTRIC INJURY, ALL SWITCHING IS CONDUCTED ONLY WITH THE POWER SUPPLY DISCONNECTED TO THE CONNECTED CIRCUIT!

If the Device is used in a place of temporary (seasonal) residence, it should be connected through a separate automatic fuse (so-called "AUTOMATIC") in order to avoid unwanted spontaneous activation of the frost protection function, and as a result - unnecessary consumption of electrical energy.

The device is connected according to the figure on the body.

Pin assignment:

1. Phase wire of the mains

2. Neutral wire of the mains

3. Heater neutral wire

4. Heater phase wire

5. Floor temperature sensor contact *

6. Floor temperature sensor contact *

    

* The instrument is shipped with a jumper on pins 5 and 6. When the jumper is installed, only the internal sensor is used to monitor the temperature. To use an external floor temperature sensor, the wire of the external temperature sensor is connected instead of a jumper.

After power is applied to the Product input, the red LED on the front panel lights up. The device is ready for use.

3. ORDER OF WORK

The appearance of the device and the liquid crystal indicator.

3.1. Press the power button (red) to turn on the instrument.The device will click the relay, connect and disconnect the load. This will illuminate the green LED on the front panel, then turn off. The indicator will show one or two indicators of the displayed temperature (SET, RT, FT) in degrees Celsius.

3.2. Press the "↑" or "↓" arrow buttons to set the desired air temperature. The indicator will show the set temperature (SET). Correct this temperature if necessary. After 5 seconds, the device automatically switches to operating mode with indication of room temperature(RT).

3. When the Product is used with a floor sensor connected, its indicator in normal operation mode shows two temperatures: the air temperature in the room (RT) and floor temperature(FT) alternately at intervals of 5 seconds.The device is set to automatically disconnect the load when the floor temperature in the sensor area is reached≥ 45° C.
