21 - REMOTE CONTROL
By connecting an interface to terminals 1-2 (fig. 7 or
8) it is then possible to:
- manually override the operation of the unit in man-
ual mode,
- activate a special short term pre-defined programme.
- remotely override the operation of the unit in
manual mode.
The set temperature refers to the last setting assigned
to the unit in MANUAL mode.
This temperature will be maintained until the unit
receives a remote deactivation command at which
point the TH450 will return to the status it was in prior
to activation.
It is possible to remotely exit MANUAL mode directly
from the machine by means of the key.
Remote MANUAL mode can be recognised by the
symbol which appears on the display next to the
symbol (fig. 75).
