3.2 Function
Mode of operation
On the underside of the module, the heat from heat
producer (e.g.: buffer) reaches the primary side of the
heat exchanger. The speed-regulated primary pump
only conveys enough heating water from the buffer for
the feed temperature required by the heat consumer
on the secondary side to be achieved.
Fig. 3-1: Primary and secondary circuits
A high-efficiency pump is installed on the secondary
side for the heat consumer; its operating mode must be
set manually. The pump characteristic curves can be
viewed under
7 "Commissioning" .
Both temperature sensors constantly provide the
ETAtouch control system with information about the
feed temperatures of the primary and secondary sides.
All components have already been connected at the
factory. Power is supplied via a 230 V Schuko socket.
Only the CAN-bus connection to the ETAtouch con-
trol panel may be established.
Contact thermostats are required for underfloor
and wall heating in order to protect the second-
ary side against overheating. If the secondary side is
at risk of frost, an additional contact thermostat must
be installed for the primary side in order to prevent the
heat exchanger from freezing.
Details about contact thermostats can be found under
6.3 "Contact thermostat" .
Uncouple the module hydraulically
Run separate piping between the system separa-
tion module and the buffer, and do not install in the flow
between the heat producer and the buffer. Otherwise,
the heat exchanger of the module will be unintention-
ally heated.
