Configuration

With the following plant types, the heating circuits are activated per default:
• Heating circuit 1 with plant types Hx-2, Hx-3, Hx-4, Hx-5, Hx-6, and Hx-7
• Heating circuit 2 with plant types Hx-4, Hx-5, Hx-6, and Hx-7
• Heating circuit 3 with plant types Hx-6, and Hx-7
Each heating circuit always has a mixing valve, pump and flow temperature sensor
preconfigured. Plant types H5-x and H6-x also have the return temperature sensor
preconfigured.
Heating circuit 1 is preconfigured based on the basic module or the RMZ782B heating
circuit module. Heating circuits 2 and 3 are always preconfigured on the RMZ782B
heating circuit module.
For more detailed information, refer to section 3.2 "Basic configuration".
