Key

1 Overheating safety (if underfloor heating)

2 Heating circuit "zone 1" (UFH shown, but can be underfloor or

radiators)

3 Climapro2 Rf programmable wireless room thermostat "zone 1"

4 2 port valve "heating zone 1"

5 Hydraulic module

6 Heating circuit "zone 2" (UFH shown, but can be underfloor or

radiators

7 Climapro2 Rf programmable wireless room thermostat "zone 2"

8 2 port valve "heating zone 2"

9 Systempro control unit

10 Wireless outdoor sensor

11 ebUS boiler

12 Heat pump electrical supply + protection (This must have it's

own single isolation)

Refer to the chapters “Hydraulic connection” and

“Electrical Connection” to connect the system.

This diagram shows the case of an installation with a

dual zone low temperature heating floor

(= outlet temperature < 40°C).

Zones must be same temperatures.
