The Ateneo pro thermostat with two air and floor temperature sensors is designed to maintain a comfortable temperature in the room according to the weekly schedule. Savings of up to 50% are ensured due to the fact that the underfloor is heated only when it is needed. The thermostat provides 3 modes of maintaining a comfortable temperature: air with floor restriction, floor, and air.
Electric and water-heated floors are controlled using data from temperature sensors. The basis of electric floor heating can be a heating cable or film. Water heated floor should be controlled by a normally closed or normally open electrothermal actuator with an operating voltage of 230 V.
Control of electric convectors, infrared panels, and other electric heaters or coolers is carried out using the built-in air sensor. In case of no voltage, the wall thermostat and heating schedule settings are kept in the non-volatile thermostat storage. In case of no voltage, the wall thermostat and heating schedule settings are kept in the non-volatile thermostat storage.
For the durable operation of the power relay and the reliability of its contacts, the following is provided:

Thermostat supports two types of sensors: analog sensor (thermal resistor) or digital sensor (DS18B20). The Analog sensor (R10) is connected to terminals 1 and 2. The digital sensor (D18) is connected to terminal 1 using white wire and to terminal 2 using blue wire. Be sure to select the type of sensor in the functional menu of the thermostat when using a digital sensor: d18 (see page 10 menu item «Type of sensor»). Power voltage (230 V ± 10 %, 50 Hz) is supplied to terminals 4 and 5, at which phase (L) is determined by indicator and is connected to terminal 5, and neutral (N) — to terminal 4. Load (connecting wires from heating element) is connected to terminals 3 and 6
When connecting via a contactor, turn on the Contactor function in the menu «Settings → Common settings
MOUNTING OF THE SENSOR MUST BE PERFORMED SO THAT IT WAS POSSIBLE TO EASILY REPLACE IT.
THE THERMOSTAT IS MOUNTED AND CONNECTED after the installation and load testing.
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, or swimming pool the thermostat should be installed at a 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. It should be designed for not more than 16 A. To protect people against electric shock leakage is installed the SSD (safety shutdown device). This event is obligatory when installing floor heating in wet areas (Wiring 1 The thermostat is mounted in the standard mounting box 60 mm in diameter, with mounting screws. For installation, you must:
The thermostat terminals are designed for a wire with a section not more than 2,5 mm2. To reduce the mechanical loads on the terminals it is desirable to use a soft wire. The wires are tightened in the terminals using a screwdriver with a blade width of no more than 3 mm with torque 0,5 N·m. The use of aluminum is not desirable. A screwdriver with a blade width of more than 3 mm can cause mechanical damage to the terminals. This may result in the loss of the right to warranty. From the mounting box with the 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 tape. The sensor is introduced into the pipe after solidifying of screed If necessary is the acceptable reduction and increase of sensor connecting wires. Near the sensor connecting wires should not be the power cables, they may be interfere. It is important to remember that it is desirable to place them on the inner wall of the room. It is recommended to store the thermostat from direct sunlight and drafts (Fig. 1). It is necessary for the thermostat to switch the current to no more than 2/3 of the maximum current specified in the specification. If the current exceeds this value, the load must be connected through a contactor (magnetic actuator, power relay), which is optimized for this current (Wiring 2).
MAIN SETTINGS
We recommend that you do the first set of the thermostat through the «Setup Wizard», which sets the basic parameters of the device. It starts automatically when you turn it on for the first time or after resetting the device to factory settings. You can enter the «Setup Wizard» in the following way
Menu → Settings → Setup Wizard
Choose the language (factory setting — Ukrainian)
Set date/time
Function use DST (factory setting — disabled
Select work control
The thermostat will maintain the temperature of the air, while not allowing the floor to overheat or cool down excessively. For this mode, enter the minimum and maximum floor temperatures
The main screen in Air with floor restriction mode will display the FLOOR icon and the floor temperature when floor restriction is triggered
Select the heating or cooling mode of the thermostat, depending on the load it controls: heater or cooler (factory setting — heating)
The Battery Saving function (factory setting — disabled) automatically turns off the thermostat at the end of the season. To do this, enter the date of the beginning and end of the season (by default — April 15 in heating mode, October 15 in cooling mode). When the thermostat reaches 00 hours and 01 minutes at this date, it will automatically turn off the battery and shut down. This will prolong the life of the internal battery, which keeps the clock running when the power is not supplied.
Be sure to set the power of the connected load for the correct statistics and air temperature measurement (factory setting 2000 W, range 100–3000 W)
If you want to maintain one set temperature, then disable the Schedule (factory setting — enabled
Main screen
Schedule
If you disabled the schedule in the «Setup Wizard», then you need to enable it.
Schedule setup
Set up a weekly schedule for the selected day according to your rhythm of life. By default, 4 periods are available during the day, it is possible to add up to 16. The schedule can be entered manually, or you can use the «Copy schedule» function
Holidays
If you spend the holidays at home, set up a separate holiday schedule (factory setting — disabled). To ensure the convenience of setting holidays, we have developed a template of public holidays for the following countries: Ukraine, Moldova, Romania, Poland, Germany, Czech Republic (factory setting — Ukraine). Select your country and then edit the holiday template we have prepared if you wish. It is possible to set up to 16 holidays.
It is also possible to set holidays in the following format:
Date/time
The stopwatch function provides for disconnecting the battery, for example, at the end of the heating season. This will turn off the thermostat completely and save battery
Away
Adjust the temperature and the Away period so that comfort is restored by the time you return. To deactivate the mode, select «away reset
Statistics
Reset the statistics before the start of the heating season to find out the estimated load energy consumption in kW*h for the selected period. For statistics, you need to set the load power.
Setup Wizard
Use it when turning on the device again or if you are not sure that you have set all the basic parameters for the operation of the thermostat.
Temperature setup
Here you can change the minimum/maximum floor temperature (for the «Air with floor limit» mode) entered through the «Setting Wizard».
Floor temperature correction/air temperature correction (factory setting 0 °С, range –10…+10 °С). You can use the correction if the temperature readings on the screen mismatch with the temperature of your reference device.
Floor hysteresis (factory setting 1 °С, range 0,1–10 °С, step 0,1 °С). A smaller hysteresis value allows more accurate maintenance of temperature, a larger one saves on energy consumption and increases the life of the relay by reducing the number of loads switching
Common settings
Sensor type (factory setting — 10K OM). The thermostat is compatible with floor sensors from most manufacturers, which allows you to replace another thermostat with a turned pro
Open Window function (factory setting — disabled) provides additional energy savings by shutting down the load for 30 minutes when the room temperature drops sharply
Рreliminary heat/cool (factory settings — disabled) use it so that the desired temperature has already been reached by the beginning of each period. According to the factory settings, the thermostat will undergo self-learning and will independently calculate the time for which you need to turn on the heating. If you prefer economy, disable this function.
Reduce to factory reset. After the reset, reconfigure the thermostat using the «Setup Wizard».
Display the device faults if any and also to display the firmware version, the total number of the relay switching, the total working time of the relay, and the number of thermostat starts
Enabling / disabling
To turn off the thermostat for a short period of time, hold down the « » button for 5 seconds. In case of a long break in the operation of the device, for example, at the end of the heating season, we recommend that you stop the clock and turn off the circuit breaker
Button blocking
It is used if the thermostat is available to children or it is installed in a public place. You need to press the leftmost and the rightmost buttons simultaneously and hold them for 5 seconds to enable/disable the lock function
