Controller types

If only a pump or twin pump is configured, the primary controller consists of system
pump control. A control loop is only obtained when configuring a mixing valve (or other
valve) so that the flow can be controlled.
If a main controller with mixing valve is used with a boiler, it must be determined
whether or not flow through the boiler is to be ensured.

Primary controller type 1:
With mixing valve or 2-port valve

Flow temperature sensor (* = optional, for display only)
B7
Return temperature sensor (* = optional, for display only)
M1
Main pump / system pump (can be a twin pump)

Mixing valve or 2-port valve
Primary controller type 1 with mixing valve or heat exchanger with 2-port valve offers
maximum limitation of the return temperature while primary controller type 2 only
provides control of a system pump depending on demand.
