Connecting to the heating system

Filling the heating system

After fl ushing the heating system the hot water cylinder must be fi lled fi rst
and then the heating system can be fi lled and pressurised.
The fi lling of the heating system is carried out via the supplied fi lling loop
sited externally to the unit.
It is recommneded that the DHW inner tank is fi lled and pressurised fi rst.
Pressure gauge
(0.5 – 1.5 bar)

Connecting to the power supply

Check that cables and printed circuit boards are intact. High and low
current cables should be routed separately in order to avoid interference
and give false readings on the sensors.

Sensors

Outdoor sensor T2
Locate the outdoor sensor T2 on a North facing wall approximately 2 m
from ground level.
Room sensor T5
Position the indoor sensor T5 to a good reference location inside the
house, away from direct sunlight and heating appliances.
The hot water cylinder must always be
fi lled and pressurised before the heat-
ing system is fi lled.
The installation must not, under any
circumstances, be switched on without
water.
Handle the circuit boards with great
care. They are sensitive to ESD (Elec-
trostatic discharge), which can cause
faults in electronic components.
