Below there is a description of system reaction when
switching from the operation into standby mode
(heating).
System I – system is stopped,
System II – system is switched on for operation, fans and
heat/cool exchanger are started, master temperature is
adjusted (in this case Tsup – air supply) up to the set tem-
perature 22°C
System III – the system is stopped, supplied air tempera-
ture and room temperature is decreasing.
Before the user starts the system, the control
