The time-programmable thermostat, when coupled with the Radio
Transceiver Base Station (figure 4.1), offers additional dedicated
function menus for the configuration of the system, which can be
accessed irrespective of the current thermostat operating mode.
Recognition of the Radio Base Station is signalled by the icon

The first time-programmable thermostat used for configuring the
system is identified as the Primary Thermostat (LOGICAL_ID 01).
All subsequent thermostats are iden-
tified as secondary thermo-
stats. For examples of
types of installations
