System diagram 14A
Common primary heat exchanger for one heat circuit with mixing valve, one heat
circuit without and a hot-water circuit with indirect control of storage tank.
Heat circuit 1
The motor valve M1 controls the flow temperature, which is measured by the sen-
sor S1. The return temperature measured by the sensor S2 can be limited. The cir-
culation pump P1 is running when the reference flow temperature is above 20 °C
or the outdoor temperature is below 2 °C.
Heat circuit 2
The mixing valve M2 controls the flow temperature in the mixing circuit, which is
measured by the sensor S4. The flow temperature measured at S4 in heat circuit 2
influences the temperature level at S1 in heat circuit 1. The return temperature
measured by the sensor S5 can be limited. The circulation pump P2 is running
when the reference flow temperature is above 20 °C or when the outdoor tem-
perature is below 2 °C.
Hot-water circuit
The hot-water circuit is connected to the secondary side of the heat exchanger, in
parallel with both heat circuits. The charging pump P3 is used to perform on/off
control of the storage tank temperature, which is measured by the sensor S6. The
circulation pump P4 maintains circulation through the storage tank but is not con-
trolled by the ECL 2000. The controller can be set up to stop P1, P2 and M2 dur-
ing tank charging.
