he Pierre system offers precise and flexible control for fan coil units, ensuring optimal indoor climate management. Fan coils are essential components in HVAC systems, providing heating or cooling through forced air circulation. Here’s how Pierre enhances fan coil control:
1. On/Off Control:
• Pierre provides simple on/off functionality for fan coil units, ensuring they are activated only when needed, based on temperature demands or scheduled automation.
2. Speed Control:
• The system allows for multiple fan speed adjustments, offering fine control over airflow. This enables the fan coil to operate at low, medium, or high speeds, depending on the room’s cooling or heating needs.
3. Temperature Adjustment:
• Pierre integrates temperature sensors to automatically adjust the fan coil’s output, ensuring consistent comfort. It regulates the temperature based on user preferences or environmental conditions.
4. Integration with Other HVAC Systems:
• Fan coil units can be seamlessly integrated with other HVAC components, such as recuperators and air conditioning systems, allowing for unified control within the Pierre system.
5. Protocol Support:
• The system supports protocols like Modbus and 0-10V, enabling smooth communication and control over fan coil systems, ensuring flexibility and compatibility across various fan coil models.
By combining on/off control, speed regulation, and temperature adjustment, Pierre provides efficient fan coil management, enhancing both comfort and energy efficiency in residential or commercial environments.

How do I ensure proper speed control with relays in my system?
Make sure that the relays are adjusted properly to control the fan speed from the slowest to the fastest setting. This will ensure smooth and effective fan speed regulation across the system.
What happens if there is a power outage?
If the power goes out, smart devices will retain their last state and resume functionality when power is restored. For critical devices, battery backups can be used to maintain operation during an outage.
Is a thermostat required?
No, a classic thermostat is not necessary. Instead, a temperature sensor integrated with the PIERRE system can monitor the room’s temperature and manage the heating/cooling devices accordingly.
Does Pierre have its own thermostat?
Yes, PIERRE offers its own smart thermostats, which can be found in the thermostat product category.
If I remove an old thermostat, can I replace it with a PIERRE display for heating control?
Yes, you can replace an old thermostat with a PIERRE display, as long as the display includes a temperature sensor for temperature monitoring.
Can a display work as a thermostat?
Yes, most Pierre displays have built-in temperature sensors and can control heating/cooling systems just like a thermostat. All displays have relays that can send signals to heating/cooling devices to turn them on or off.
How can heat quantity measurement be solved with the PIERRE system?
To measure heat quantity, a PIERRE Pro Controller and an Intesis Mbus to Modbus converter are required. The heat meters are connected in series to the PIERRE Controller.
Can I adjust different temperatures in different rooms?
Yes, you can control the temperature room by room.
In a multi-apartment system, how should the circulation pump be controlled?
The circulation pump’s operation is based on automation, so if the valve in any apartment’s floor heating system is activated, it simultaneously activates the circulation pump. If separate control is needed, it can only be handled locally within the apartment.
Regarding heating and cooling, how can I set it up later to ensure the requested hot or cold water reaches each apartment? How can I start the circulation pump per apartment?
Starting from the apartments, the process works as follows: humidity and temperature values are measured in the apartments. To reach the desired temperature, we control the distribution manifolds in the apartments. The circulation pumps for each floor are turned on when any apartment’s distribution manifold valve is open.
Can we program PIERRE so that the valve opens at a given temperature and the pump starts in the valve open position?
Yes, this can be solved per manifold. Alternatively, PIERRE can be programmed so that the valve opens at a certain temperature and the pump starts when the valve is in the open position.
How will the heat pump be connected to the PIERRE system?
The heat pump can be controlled by PIERRE in two ways:
- Winter and summer modes can be switched via a potential-free contact, and a similar contact can be used for starting and stopping the heat pump (start/stop function).
- Modbus RTU communication. It’s important to consult the manufacturer or distributor in advance about the Modbus register addresses and required documentation based on the heat pump model to ensure the proper control process.
Which types of fan coil units can be integrated into the system?
The simplest fan coil units to control are those that can be turned On and Off via relays, with each speed level controlled by separate relays. There are also fan coils that can be controlled using a 0-10V signal, which can also be integrated into the system. Additionally, Modbus communication is possible, but in this case, it is important to consult the manufacturer or supplier in advance regarding the Modbus register addresses and the necessary detailed documentation to ensure the control process is implemented correctly.
What equipment can be controlled by the PIERRE system for starting heat pumps, hot water tanks, and motorized valves in underfloor heating zones?
The motorized valves for underfloor heating zones can be controlled without any issues by the PIERRE system, whether they are On-Off or 0-10V valves. In the mechanical room, the PIERRE system handles the following controls: winter-summer mode switching via a potential-free contact, circulation pump control, hot water circulation pump control, and 0-10V mixing valve control with supply water temperature measurement.
