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

Refer to the chapters “Hydraulic connection” and
“Electrical Connection” to connect the system.
i DHW components only necessary with sealed
system or open vented installations. Hot water
production can be via a combi boiler instead.
b 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.
