About the thermostat
Network set-up with a controlling
master thermostat
If more Devireg 550™ thermostats have been
installed in the house, the electrician may have
chosen to link them together in a network with
one thermostat serving as master unit control-
ling various settings on the other thermostats in
the network (also called slaves). In that case the
following settings are controlled by the thermo-
stat that has been congured as master:
• Time
• Weekday
• Economy set-back
If the thermostats are linked in a network, any
changes of time, weekday and/or periods with
lowering of temperature must be made on the
thermostat congured as master. e changes
will then take eect on all slave thermostats.
Please contact the electrician to nd out if the
thermostats in the house are linked in a network,
and in case they are, which thermostat has been
congured as Master.
