Description

The HVAC with Blower Speed Control category focuses on managing any heating, ventilation, or air conditioning devices that feature adjustable blower speeds. Similar to fan coil systems, this category includes various HVAC units where blower speed is critical for regulating airflow and maintaining comfort levels.

    1.    Blower Speed Control:
    •    These HVAC units allow for adjustable fan speeds, offering precise control over the airflow to suit different cooling or heating requirements. The Pierre system can manage these speeds based on real-time temperature data, ensuring efficient climate control.
    2.    On/Off and Speed Adjustments:
    •    In addition to on/off functionality, Pierre enables control of multiple blower speed levels, allowing the system to adjust between low, medium, and high speeds as needed to optimize airflow and energy usage.
    3.    Temperature Sensor Integration:
    •    By integrating with temperature sensors, the system ensures that the blower speed adjusts dynamically to maintain the desired temperature in the room, improving energy efficiency and comfort.
    4.    Compatibility with Various HVAC Devices:
    •    This category covers a range of devices beyond fan coils, such as air conditioners, ventilators, and other units with variable blower speeds. Pierre provides a unified control interface for all these systems.
    5.    Wireless and Wired Control:
    •    The Pierre system supports both wireless (Zigbee) and wired control options, offering flexibility for installations in new buildings or retrofit scenarios.

By offering precise blower speed control, Pierre enhances the performance of HVAC units, ensuring efficient and flexible operation for a wide variety of heating and cooling devices

Troubleshooting
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.
 

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:

  1. 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).
  2. 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.
