The Pierre controller works seamlessly with Modbus thermostats to provide precise control over heating and cooling systems. Through the Modbus protocol, the thermostat communicates with the Pierre controller, allowing users to regulate temperature efficiently across various zones or systems.
Key Features:
1. Temperature Control: The Modbus thermostat sends real-time temperature data to the Pierre controller, which adjusts heating and cooling accordingly. This allows for smooth on/off control of HVAC systems or more precise management through frequency regulation.
2. Automation: The Pierre controller can automate the thermostat’s functions based on conditions like time, external temperature, or user preferences. This ensures that heating and cooling are adjusted automatically for comfort and energy efficiency.
3. System Flexibility: The integration supports various heating and cooling setups, such as floor heating, fan coils, and other Modbus-compatible systems, offering wide versatility in different environments.
By combining the power of the Pierre controller with Modbus thermostats, users can enjoy flexible, precise, and automated climate control in their homes or offices
Does MODBUS Thermostat work without PIERRE?
If not: Is it energetically well-connected and is there power?
What color mean what on Controller LED?
Green – Online:
The controller is online and connected to the network, functioning as expected.
Red – Offline:
The controller is offline, indicating a disconnection from the network or that there is no internet access.
Light Blue – AP Mode:
The controller is in Access Point (AP) Mode, meaning it is broadcasting its own network, allowing devices to connect directly to the controller for setup or configuration.
Dark Blue – AP Mode with Pierre Partner:
The controller is in AP Mode, and it is actively being managed through the Pierre Partner system. This mode is used for more advanced setup or partner-level configuration.
Purple – Searching for IP Address:
The controller is attempting to obtain an IP address from the router or network. It is searching for an internet connection.
Orange – Firmware Update:
The controller is in the process of downloading a firmware update, ensuring that the system stays up-to-date with the latest software and features.
These LED color indicators provide essential information about the controller’s current status, making it easy to monitor its connection, operation mode, and maintenance activities.
Has the device been added to the configuration?
If not: Add it in the PIERRE Partner application.
Are the GND and OUTPUT cables properly connected and does the LED on the relay board light up?
If not: Check the polarity of the relay, maybe they are reversed. To rule out the relay issue, provide 12VDC directly from the power supply to the relay signal wire instead of the output.
Are the wires connected to the relay?
If not: Check all connections of the relay. Does the Line (L) connected? Are the correct wires connected?
If manually heating the thermometer doesn't increase its value?
If not: Let's check what might be wrong with the thermometer.
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:
- 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.
