How to lock the thermostat in the app

In the app, choose “Detail”. Choose the settings icon and choose “thermostat lock”. Turn the lock on and off by choosing “Confirm”. The thermostat is now locked. 

The LED light on the control unit of a channel shows overload. Flashing red fast

Why: More than the max 2 thermo-actuators or other device connected to the output The power consumption of the device it too high

Solution: The connected device consumes too much power. Connect max. 2 thermal actuator to separate outputs of the CCU and max. 1 thermal actuator per channel of the EU-A. Check that the connected device operates with 24 V/DC with a load of no more than 1W/0.4 A. Replace the connected thermo-actuator in case of bad/damaged/broken wiring.

The LED display of the thermostat/sensor does not ‘awake’ at touching. Not responding

Why: No input of that particular room/zone to the control unit. Wrong type of BUS cable is used or BUS cable connected in a wrong way. The batteries are empty for the wireless room thermostats/ sensors

Solution: Fault in wired connection between the control unit and the wired room thermostat/sensor. Check for correct connections at the control unit and the wired room thermostat/sensor, and check if the wiring is of the correct type and in good condition (not twisted or damaged) and well connected to the control/extension unit. Replace the batteries.

Connection with thermostat/sensor lost / temporary interrupted.

Why: Fault in wired connection between the control unit and the room thermostat/sensor. Use of incorrect cable type. Weak wireless signal

Solution: Check for correct connections at the control unit and the room thermostat/sensor and check if the cable is connected correctly. Check for continuity from one end of the wire to the other end and make sure there is no short circuit between individual wires. Check that the room thermostat or control unit is not mounted on a metal surface or housing. Check for non-certified wireless products within the range of their control system. In case situation continues an external antenna is available to improve the signal strength.

Room thermostat/sensor cannot be enrolled/ connected to the control unit

Why: The control unit does not receive the link signal. The room thermostat does not send a link signal

Solution: Check that the LED light of the output channel indicates that the control unit is ready to be paired (Technical Handbook, paragraph 4.1.1). Place the batteries inside the wireless thermostat/sensor, check correct battery position and start enrolling proves (Technical Handbook, paragraph 4.4). See symptom “Connection with thermostat lost / temporarily interrupted”

One or more rooms become overheated

Why: Room thermostats/ sensors control the wrong outputs.

Solution: Reset incorrectly linked outputs and connect them to the correct room thermostat. Label the output on the manifold and check corresponding thermostats/sensors in the room.

Thermostat is showing a “no entry sign”

Why: Thermostat is in synchronization mode

Solution: Wait a little bit for the thermostats to initialize (Technical Handbook, paragraph 8.5)

Pump is not starting

Why: Pump delay is active Pump 2 is not assigned

Solution: Pump will be delayed so outputs can open first. Change pump delay in LCD commissioning tool System | Installer Settings | Hardware profile | Configure Outputs Assign rooms and outputs to pump 2 (default pump 1) in LCD commissioning tool System | Functions | HCC/ITC | Room Assignment

The Smart Radiator Thermostat is giving an error “installation incorrect”

Why: Calibration function did not detect valve

Solution: Make sure the the Smart Radiator Thermostat is connected to the radiator valve and re-insert batteries to restart the calibration function.

My control unit is showing white LEDs during installation?

Why: First Opening of Actuators function is active

Solution: This functions makes sure the actuators will close properly. Our actuators have an easy to install function, they are delivered half open, to close they will need to fully open first. Commissioning of the system can continue as normal, the FOA function will take about 10-20min. After that testing can be done if needed. There is no way to switch off this function. (Technical Handbook, paragraph 4.1)

Cooling blocked / room LED blinking blue on the control unit?

Why: Dew point protection is active. Inlet sensor missing, cooling not protected.

Solution: In cooling mode Sentio is protected against risk of condensation. Dew point is calculated per room and compared to the inlet temperature or floor temperature. If the inlet temperature would go below the dew point cooling will be blocked to avoid condensation. For cooling mode there is always a inlet sensor needed to ensure the system will be save. The function cannot be switched off but the safety margin can be changed in the LCD commissioning tool: Programs | Summer/winter mode| Cooling settings

The Control unit is showing purple room LED

Why: Room with only radiator control using Smart Radiator Thermostats

Solution: Room only has SRT (no actuator, PID control), there is no clear ON/OFF control. The radiators can be a bit open and still feel warm, although it is not expected to be fully heating. (Technical Handbook, Paragraph 4.4)

Warning message saying “Incompatible periphery detected please update software”

Why: Component firmware version is lower than control unit firmware version

Solution: Control unit should have firmware available to update all components to the same firmware version to avoid any unexpected issues. Activate the auto-update function to update components where needed, even without internet connection. (Technical Handbook, Paragraph 6.2)

Can Sentio work via an BMS? External thermostats via modbus?

Find more information: Modbus Manual in Appendix 8.8

Sentio can be connected as slave to a Building Management System via Modbus RTU and TCP/IP. The Sentio system itself will still be in charge of the underfloor heating. It is not possible for the BMS to take over Sentio’s outputs, that would take away the functionality of Sentio

Does the Smart Radiator Thermostat (SRT) need a room thermostat?

Find more information: SRT Manual in Appendix 8.4

Depends on the situation, the Smart Radiator Thermostat can work stand alone but requires the APP to set the temperature. In cases where it cannot accurately estimate the temperature a room thermostat can be added. When both are added to the same room the Smart Radiator Thermostat will automatically switch its control to the room thermostat.

How do I rename rooms?

Renaming rooms in the commissioning touch screen makes it easier for future maintenance and remembering where UFH loops go.

The set name will be imported to the APP. The end user can change the display name of the room as desired. Often there are some question marks when changing the name in the APP, it will not update the display name, this is because the two are separate names, to update the names the APP widgets will need to be removed and re-added with the new name.

What is the maximum number of components that can be added into one Sentio system?

Find more information: Technical Handbook, Paragraph 3.0

See the list for maximum components in paragraph 3.0 or the Sentio Quick Guide.
