6.3.17 Application 16, Type 2 Only
System diagram 16A
Two separate heat circuits. Hot-water circuit with indirect control via heat ex-
changer.
Note:
ECL 2000 Type 2 must be used to control this application.
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 motor valve M2 controls the flow temperature, which is measured by the sen-
sor S4. The return temperature measured by the sensor S5 can be limited. The cir-
culation pump P2 is running when the reference flow temperature is above 20 °C
or the outdoor temperature is below 2 °C.
Hot-water circuit
The motor valve M3 controls the hot-water temperature, which is measured by the
sensor S10. The return temperature measured by the sensor S11 can be limited.
The circulation pump P3 is controlled according to the ECL 2000’s 7-day program
and the hot-water temperature (the pump is active when the reference hot-water
temperature is above 20 °C).
