Sample circuits
The switching power of the relays on the NEO is 5 amperes. This means that if
consumers with a power rating in excess of 1100 W are to be connected, a
contactor should be used, otherwise the relays could be destroyed.
A dotted box may be illustrated in the circuitry. This is
a branch box. The power line enters this branch box
from above, while the line to the consumers exits from
below it. From the side, another line goes to NEO to
retrieve the relay contact.
10.1. Controlling the accumulator change pump
The accumulator charge pump is connected directly to the "PUMP OUT" output.
The connector and the cable housing are provided. Two further PT1000 sensors
are required. One must be installed in the fireplace and be connected to PT1
while the other (top) must be connected to the buffer storage unit as PT2. Relay
1 must be assigned the "Differential temperature" function. Everything else is
already pre-set.
Use of cable housings, see chapter 3.4. !
