2Introduction
Congratulation with the purchase of this
thermostat ModuLine 300.
The thermostat ModuLine 300 is intended for
operating and regulating the Nefit boiler in
your home.
The ModuLine 300 can be connected to all
boilers, which are listed in table 1.
Advice:
zHave the installer explain the thermostat.
zRead this manual carefully before use.
2.1 General
The ModuLine 300 thermostat is easy to
operate. At the right side of the display are
four buttons. These buttons allow to quickly
switch between the time program and manual
operation, or information be obtained of the
settings of the thermostat and the boiler.
At the bottom of the cover are a number of
buttons for the set-up of the thermostat
function. Usually, these settings only have to

During the navigating, there appear
accompanying texts on the display. By means
of "question and answer" can set-ups easily
be carried out.
Installation, maintenance en repairs
