7.5.9.2 Ambient temperature reached
The intent of this output is to give a signal to a potential Fan coil system when the Room air temperature, measured
by the Remote controller, is reached, so that the Fan coils will stop. When the Fan coil system is restarted by the
predetermined Room air temperature hysteresis, transmission of the signal is halted.
This signal can be used like a window contact by the Fan coil to stop the Fan coils and/or water valves.
In case of Par0400=1, if the Room air temperature detected by the Remote controller has not reached the set
point, the Terminal47 will be closed.
In case of Par0400=2, if one of the Room air temperatures detected by Master or Slave Remote controller has not
reached the set point, the Terminal47 will be closed.
