Key

1 Heat pump

2 Systempro control unit

3 "Compact" hydraulic module

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

own single isolation)

5 Wireless outdoor sensor

6 Domestic hot water cylinder

7 EBUS boiler

8 Climapro2 RF programmable wireless room thermostat "zone 2"

9 Heating circuit "zone 2" (UFH shown, but can be underﬂ oor or

radiators)

10 2 port valve "heating zone 2"

11 Domestic hot water cylinder 2 port valve

12 Climapro2 RF programmable wireless room thermostat "zone 1"

13 Heating circuit "zone 1" (UFH shown, but can be underﬂ oor or

radiators)

Refer to the chapters “Hydraulic connection” and

“Electrical Connection” to connect the system.

DHW components only necessary with sealed

system or open vented installations. Hot water

production can be via a combi boiler instead.

This diagram shows the case of an installation with a

dual zone low temperature heating ﬂ oor

(= outlet temperature < 40°C).

Zones must be same temperatures.
