2.5 Mounting and installation of the thermostat
*TPI is a built-in energy-saving control algorithm that ensures a
stable temperature in the rooms.
**The NSB function is only available if the system is equipped with
at least one weekly programmable thermostat (master). There is no
need to remove the jumper in case there is no master thermostat.
***If a programmable thermostat (master) is connected to the
system and the NSB function is active, the HTR-RF(20) thermostat
will automatically adjust the temperature decrease value according
to the jumper settings.
