The energy-saving controller registers the cooling mode via the C/O IN input and can control the individual thermal circuits accordingly.
Auto-inverting
In the app you can set whether the room thermostat signal should be inverted. With "Auto-inverting", the room thermostat automatically detects whether the system is in cooling mode and automatically carries out signal processing (prerequisite: c/o out of the energy-saving controller is connected to the master room thermostat).
Non-inverting
With "Non-inverting" there is no connection between the c/o out and the room thermostat, or the room thermostat does not have a corresponding remote station. In this case, the controller inverts the room thermostat signals when switching to cooling mode (signal from cold source at c/o in).

10.3. Functions
To set or activate the functions, the energy saving controller must be connected to a tablet or smartphone via the Flamconnect app.
10.3.1. Flushing function
The flushing function is usually required by the installer when the heating system is commissioned. During flushing, the air from the heating circuits is flushed and separated. The heating water is pumped through the heating circuits in series at maximum speed to flush air bubbles out of the pipes. The automatic flushing process must be started in the app and will then run automatically and independently of the app.
At the end of the flushing process, the flushing function must be terminated in the app again. Only then does the energy-saving controller go into normal operation mode.

Supply line
Aer commissioning, the "Screed protocol" function can be activated.
The supply line temperature is recorded at regular intervals. The data can then be used to create the screed heating log.
This function can be activated even if no actuators have yet been installed. However, it must be ensured that all valves including all supply line and return valves are open.
If the actuators are already installed, they must be removed and the valve opened manually. The sequence of the actuators must not be confused ifcommissioning has already been carriedout.
Otherwise, the actuators will have to be reassigned.

10.3.3. Valve and pump protection function
To ensure operational safety, the valves and the pump of the fixed-value control set are moved automatically during longer periods of inactivity. Aer a power failure, an automatic reference run is performed. We therefore recommend keeping the unit permanently under power.
10.3.4. Function of switching valve
This function enables individual control of a switching valve via the 0-10 V output. The configuration takes place in the app under "Advanced Function".
10.3.5. Function of radiators
If radiators are connected to the heating circuits, they can be parameterised with dierent properties:
a. Radiators without thermostatic valve: These are controlled similarly to surface heating circuits via the respective room thermostat. b. Radiators with thermostatic valve / thermostatic head on the radiator: In this case, no room thermostat is assigned to the circuit.
Thevalve of the corresponding heating circuit is permanently opened and hydraulically balanced. The control is based on the design value [W]. The heating circuit is opened by means of the thermostatic valve / thermostatic head.

10.4. Function monitoring
10.4.1. Supply line temperature
If the maximum permissible supply line temperature (factory setting 55 °C) is exceeded in heating mode, all valves are closed.
In cooling mode, all valves are closed if the minimum permissible supply line temperature of 15 °C is not reached.
10.4.2. Comparison of supply line / return line temperature
During heating operation, the spread between supply and return line temperature is constantly monitored. If the temperature in the return line rises above the supply line temperature, the corresponding valve is closed.
10.5. Data export
The values set or recorded in the energy saving controller can be conveniently exported via the Flamconnect app and then used for further logging purposes such as the commissioning log or the screed heating log.
For this purpose the exported file can be imported into the respective template.

Secos - Simplex Energy Control System
13. FAQ
1. What is Secos?
Secos means Simplex Energy Control System and is a highly
innovative control system for surface temperature control.
2. How does Secos work?
Due to a constant volume flow and temperature measurement
in each heating circuit the hydraulic balancing values are optimally and immediately adjusted.
3. How does the commissioning take place?
When the Secos energy-saving controller is connected for the
first time with the "Flamconnect" app, you will be prompted toperform the commissioning.
You will be guided step by step through the required process.
4. Do you need to set more?
The hydraulic adjustment starts to work at the point of input
ofthe above-mentioned values. However, all settings can be modified and additional functions specified later.
5. Can conventional room thermostats be used?
Secos is very flexible and can be used with all 230V room
thermostats which generate an analogue signal such as a two-point or PWM signal.
6. Do the valves stick?
No, the ceramic disc valves are designed, and the material
selected, to ensure that the valves remain free, durable and reliable. Additionally, any longer downtimes of individual valves will be detected and the valves moved at periodic intervals, to maintain freedom.
7. How sensitive are the Secos multisensors?
The Secos multisensors do not contain any moving parts.
Theyare therefore wear-free and function even with dirty water.
8. What happens in the event of a defect or fault?
In such an event, the Secos Energy Saving Controller will
register a warning signal. Then, the smartphone or tablet which is connected via the Flamconnect app to the Secos energy saving controller can be used to carry out a detailed analysis.
9. How does flushing take place?
There is an automatic flushing program, which can
conveniently be started after connection (e.g. using flushing equipment) via the "Flamconnect" app. The automatic flushing program flushes the heating circuits separately and automatically until a reliable and constant volume flow isdetected by the Secos multisensors.
10. Can I also shut off heating circuits without a Secos actuator?
Yes, the Secos disc valves can be manually opened and closed
in the supply and return lines.
11. Is Secos compatible with other laying systems?
Secos is compatible with all commercially available underfloor
heating laying systems such as staple, nub plate, hook and loop, drywall, support matting and renovation systems
12. Can all underfloor heating pipes be used?
All commercially available underfloor heating pipes can be
used. These are connected with the Secos system manifold using Eurocone compression fittings.
