SOLARFOCUS Distribution

Use cases

• Monitor flow temperatures and mixing valve positions of two heating circuits on a live cloud dashboard.
• Set target flow temperatures and operation modes remotely to adjust comfort levels without a site visit.
• Create an alert when buffer storage top temperature drops below a defined threshold for early fault detection.
• Log hot water storage temperature over time to verify domestic hot water performance and setpoint compliance.
• Combine this template with SOLARFOCUS heat pump or pellet boiler templates to supervise the full heating system.
• Release or disable cooling mode for individual heating circuits remotely during seasonal transitions.

Installation

1. 1Connect the SOLARFOCUS ecoManager-touch controller to your local network via Ethernet and note its IP address.
2. 2Wire the ModbusCloud gateway (MCG or MLP series) to the same local network, ensuring it can reach the controller IP.
3. 3In the ecoManager-touch settings, verify that Modbus TCP communication is enabled and confirm the default TCP port (typically 502).
4. 4Import the SOLARFOCUS Distribution template in the ModbusCloud platform and assign the controller IP address and port.
5. 5If external room temperature sensors are used, configure registers 32606 and 32656 as writable inputs in the template settings.
6. 6When combining with other SOLARFOCUS templates (heat pump, pellet, biomass), import those additional templates for the same gateway and verify there are no register address conflicts.

Things to watch for

01

Why do I need multiple SOLARFOCUS templates instead of just one?

The Distribution template covers heating circuits, buffer storage, and hot water storage only. Heat generation equipment such as heat pumps, pellet boilers, or biomass boilers each have their own register sets and require a separate dedicated template.

02

What are the writable room temperature registers (32606, 32656) used for?

These registers allow you to send an external room temperature value to the ecoManager-touch controller. If you have room sensors connected through the gateway rather than directly to the SOLARFOCUS system, write the measured value to these registers so the controller can use it for regulation.

03

The gateway connects but no data appears on the dashboard. What should I check?

Confirm that Modbus TCP is enabled on the ecoManager-touch and that the IP address and port (usually 502) match the template configuration. Also verify that no firewall or VLAN boundary is blocking traffic between the gateway and the controller.

04

Can I control cooling release remotely through this template?

Yes. The template includes Release Cooling registers for HC1 and HC2. Writing the appropriate value activates or deactivates cooling mode for each circuit independently.
