Windhager Best Heating Technology Log Wood Boiler

Use cases

• Monitor boiler temperature and buffer tank levels on a live cloud dashboard for residential heating customers.
• Create an alert when remaining maintenance hours drop below a threshold to schedule proactive service visits.
• Adjust comfort setpoints for HK1 and HK2 remotely without traveling to the installation site.
• Track pellet consumption and operating hours over time to optimize fuel purchasing and boiler efficiency.
• Activate the party timer remotely when a customer needs temporary heating outside the normal schedule.
• Log hot water temperature deviations from setpoint to diagnose domestic hot water performance issues.

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the Windhager LogWIN2 boiler via Ethernet.
2. 2Ensure the InfoWIN Touch display is updated to Modbus TCP software version V3.1.0 or higher by contacting Windhager Customer Service if needed.
3. 3Verify that the LogWIN2 boiler runs Software V1.00 or higher (available from April 2025).
4. 4Configure the Modbus TCP IP address and port on the InfoWIN Touch display so the gateway can reach the boiler.
5. 5Import the Windhager LogWIN2 log wood boiler template in the ModbusCloud platform and assign it to the connected gateway.
6. 6Confirm that sensor readings such as boiler temperature and buffer tank temperatures appear correctly on the ModbusCloud dashboard.

Things to watch for

01

Which Windhager models are supported by this template?

Only the LogWIN2 DELUXE and LogWIN2 EDEL are supported. The boiler must run Software V1.00 or higher. MES+, MES Infinity, and Infinity-TA systems are not compatible.

02

Do I need to update the InfoWIN Touch display before using Modbus TCP?

Yes. The InfoWIN Touch display must be updated to software version V3.1.0 or higher. Contact Windhager Customer Service to order the free update.

03

What data types and scaling are used for temperature registers?

Temperature values use int16 or uint16 data types with 1-degree Celsius resolution. No decimal scaling is applied. Time registers are expressed in hours or minutes.

04

Can I connect the gateway over Modbus RTU instead of TCP?

No. This template uses Modbus TCP only. The LogWIN2 boiler must be connected via Ethernet on a local network accessible by the ModbusCloud gateway.
