tekmar 482 tN4 Gateway - Manual (Page 10)

© 2012 D 482 - 01/12 10 of 12
Before connecting the tN4 Gateway to a tekmarNet ® system,
it is recommended that the system be fully completed, with
no tekmarNet
® thermostats being added or removed at a
later date. Also, each tekmarNet ® thermostat is automatically
assigned a tekmarNet ® address when connected to the
system. When using a Gateway, each device requires a
manual address. This address should be written down
together with the room location for future reference using
the Job Record J 482 and will be required in order to name
the room on the home automation equipment.
