The Pierre system leverages advanced communication protocols like MODBUS, 0-10V, and MQTT to offer precise and flexible control over heating and cooling systems. These protocols ensure that HVAC units are integrated smoothly, allowing for detailed management and automation.
1. MODBUS (Serial Communication Protocol):
• MODBUS is ideal for controlling complex HVAC systems, offering precise real-time adjustments of parameters like temperature, humidity, and fan speed. It is widely used to control heating systems, air conditioners, and ventilation units, providing reliable performance in both residential and commercial applications.
2. 0-10V:
• The 0-10V protocol allows for smooth, incremental control of heating and cooling equipment. It’s commonly used for fan coils and other HVAC devices, enabling the adjustment of speeds and output based on voltage levels. This provides more granular control over temperature and airflow.
3. MQTT (Message Queuing Telemetry Transport):
• MQTT is a lightweight IoT protocol used to ensure efficient communication between multiple devices, such as temperature sensors and HVAC controllers. It is perfect for large systems where data from various sensors needs to be processed in real-time, ensuring that the heating and cooling systems respond dynamically to environmental changes.
By using these protocols, Pierre enables seamless integration and precise control over heating and cooling systems, enhancing energy efficiency and user comfort
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.
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.
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.
