2. Product Overview

The RT310 room thermostat switches the heating system on and off as necessary by sensing the air temperature. It turns the heating on when the air temperature falls below the thermostat setting and off once the set temperature is reached. It is recommended for controlling heating panels or electric heaters.

Turning a room thermostat to a higher setting will not make the room heat up any faster; heating speed depends on the system design (e.g., boiler and radiator size). Similarly, it does not affect how quickly the room cools down. Setting a lower temperature controls the room at a lower temperature, saving energy.

The heating system will not work if a time switch or programmer has switched it off.

To set and use your thermostat, find the lowest temperature setting you are comfortable with and leave it. The best approach is to set the thermostat to a low temperature (e.g., 18°C) and increase it by one degree each day until you reach your desired comfort level. Adjusting it higher will waste energy.

For boiler systems with radiators, a single thermostat usually controls the whole house. You can achieve different temperatures in individual rooms by installing thermostatic radiator valves (TRVs) on radiators. If TRVs are not present, choose a temperature suitable for the whole house. With TRVs, you can set a slightly higher temperature to ensure comfort in the coldest room, then adjust TRVs to prevent overheating in others.

Thermostats require free airflow to sense temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, or lamps can affect proper operation.

2.2 Proper thermostat location

[Diagram: Illustration showing recommended thermostat placement on a wall, indicating a minimum distance from the floor (e.g., 1.5m) and away from heat sources like radiators or direct sunlight.]

Please note:

The ideal position for thermostat mounting is about 1.5m above floor level, far from heating or cooling sources, and protected from direct sunlight or extreme conditions like drafts. Due to fire and explosion risks, the thermostat must not be used in atmospheres with explosive gases and flammable liquids (e.g., coal dust). If such dangers exist, additional protection measures like an anti-dust and explosive gases (tight cover) are required, or their formation must be prevented. Furthermore, the thermostat cannot be used in conditions of water vapor condensation or be exposed to water action.

9. Test the pairing process

It is important to place the receiver and transmitter in locations where nothing interferes with the radio signal. The range of communication between the transmitter and the receiver in an open area is up to 60m. Radio transmission is influenced by factors that can shorten the working distance, such as thick walls, drywall covered with aluminum foil, metal objects (cabinets), and general radio interference. However, the range is sufficient for most domestic use. It is recommended to test the radio transmission between devices before mounting the regulator on the wall. The test can be performed by changing the set temperature, i.e., by activating or deactivating the heating.

1. Press the [TEST/PAIRING] button to check the connection with the receiver.
2. The antenna icon ? will display. Test mode can take up to 9 minutes.
3. The green LED on the SR868 smart plug receiver will begin to flash.
4. Press the [TEST/PAIRING] button again to return to the main screen.
5. The SR868 will go back to normal work mode.

[Sequence of images: Step 1 shows pressing the button. Step 2 shows the antenna icon. Step 3 shows the receiver LED. Step 4 shows returning to the main screen. Step 5 shows the receiver returning to normal.]

If you purchased an SR868 or RT310TX and intend pairing with other devices in the 5x5 range, please refer to the Receiver Units manual or the relevant manuals available at www.salus-controls.eu.
