Network installation
If more ECtemp 550 thermostats have been installed, they
may be connected in a network. If so, one of the thermo-
stats is defined as the master unit controlling the time, day
of week and lowering of temperature during economy peri-
ods for the other so-called slave units. This means that
changes to these settings must be made on the master
thermostat and will then automatically take effect on all
"slave" thermostats.
Please contact the electrician to find out if the thermostats
in your house are linked in a network and, if so, ask which
thermostat is configured as master unit.
