◆ Emergency Operaon
Space Heang:
Enable or disable emergency
operaon for space heang.
Only available in case “Heang
source” on “1.8.2.7 Complementary
Heang conguraon” contains
“Electrical heater or boiler” opon
DHW:
Enable or disable emergency
operaon for DHW. Only available
when electrical heater for DHW is
enabled (by DSW).
Mode:
Selecon of the emergency operaon
mode:
• Manual: Emergency operaon is acve
when is manually enabled (by DSW4
pin 4 ON). The emergency mode uses
the heater (space heang or DHW) to
provide the required heang.
• Automac: Emergency mode operates
when there is an event of outdoor
unit failure and Demand ON of space

energy consumpon calculaon.
• ECO C1 + C2: Switch both Circuit 1 and Circuit 2 to ECO mode when input is closed.
• ECO C1 (by default in input 2, if there is circuit 1 in the installaon): Switch Circuit 1 to ECO
mode when input is closed.
• ECO C2: Switch Circuit 2 to ECO mode when input is closed.
• Forced O: Forbid DHW, space heang and space cooling.
