DEVI Devireg 550 User Manual page 9

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 configured 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 configured as master. The changes
will then take effect on all slave thermostats.
Please contact the electrician to find out if the
thermostats in the house are linked in a network,
and in case they are, which thermostat has been
configured as Master.
