INTRODUCTION
MURELLE HM ErP
are premixed gas con-
densation thermal modules that employ
a microprocessor-based technology to
control and manage all the functions.
The wide field of modulation of the heat
power (from 10% to 100%), decreases the
switch-on and off cycles and, in case of
integration with solar systems, guaran-
tees maximum D.H.W. comfort.
For optimum installation and operation,
always follow the instructions provided in
this manual.

Murelle HM 25 T - 35 T ErP (fig. 1)
ATTENTION:
The “25 T - 35 T ErP” version is
designed for the connection of
a remote boiler, to use it as a
boiler ONLY FOR HEATING it is
necessary:
- to disconnect the D.H.W. sen-
sor (SB)
- set the PAR 2 to 5.
All modules are designed to be
used by qualified technical per-
sonnel.
