External enable signals can be configured directly in Configuration/1:
For more details on input configuration, see ANALOG AND DIGITAL INPUT MULTIPLEXER.
Heat/Cool enable channel
This parameter allows you to specify which digital input of the System is used as external signal for enabling the Heating and/or Cooling function.
If the enable signal is configured, it contributes, together with other factors, to the activation of the system (see SYSTEM ACTIVATION AND SEASONAL CHANGE).
System enable channel in Summer
This parameter allows you to specify which digital input of the System is used as external signal for enabling the system in cooling mode (summer).
Closing the contact also sets the system’s Current Season to Summer, and therefore the System will operate in Cooling mode.
If the Summer mode enable signal is configured, it contributes, together with other factors, to activate the system and determine the Current Season (see SYSTEM ACTIVATION AND SEASONAL CHANGE).
System enable channel in Winter
This parameter allows you to specify which digital input of the System is used as external signal for enabling the system in heating mode (winter).
Closing the contact also sets the system’s Current Season to Winter, and therefore the System will operate in Heating mode.
If the Winter mode enable signal is configured, it contributes, together with other factors, to activate the system and determine the Current Season, (see SYSTEM ACTIVATION AND SEASONAL CHANGE).
Select Season Channel
This signal allows you to specify which digital input of the System is used as external signal to determine the system’s Current Season.
If the Current Season selection signal is configured, it contributes, together with other factors, to determine the Current Season (see SYSTEM ACTIVATION AND SEASONAL CHANGE).
Canale per l’abilitazione della VMC
Questo parametro permette di specificare quale ingresso del Sistema viene utilizzato come segnale esterno per determinare l’abilitazione della funzione VMC (Ventlazione Meccanica Controllata).
Per maggiore informazioni sulla funzione VMC vedere EN_FUNZIONE VMC CON OROLOGIO E/O SENSORE VOC.
Attenzione
Una volta definiti canali di abilitazione esterni per l’ON/OFF dell’impianto e/o per il cambio stagionale, non sarà più possibile fare il cambio stagione o l’accensione dell’impianto dai touch screen, da app o via Web.
Nota
Anche l’ACS ha il suo comando di abilitazione da segnale esterno (vedere DHW SET POINT)
