25. FIRE MODE
It is possible to assign a digital input to the FIRE function. After receiving the signal from an external fire control unit, a
predetermined behavior of the heat recovery unit fans will be forced .
Input signal type: Voltage-free contact.
SLIM control panel is supplied with a bridge to avoid the appearance of the alarm (contact open = Alarm) See section
"14.2. Corrigo controllers", and check “CONTROLLER 2” wiring diagram for details. As you can see, Fire Alarm input is
placed in terC2 & 27. It is possible to look for this information in section "14.3.5. Inputs & Outputs", too.
Regarding the Fire Mode function, it is possible to assign the following fire alarm strategies:
Strategy Description
Continuous
run Supply air fan will run at maximum speed while the extract air fan will:
a) follow the “normal” set point if the unit was running at “normal speed” or “reduced speed”
before the activation of the fire function
b) follow the “extra” set point if the unit was running at “extra speed” before the activation of the
fire function
• The unit will continue running no matter any other alarm appears (no unit autoprotection).
• The unit will not respond to “OFF order”. The unit will stop only by switching off the supply.
Normal
running Similar to Continuous run but the unit will respond to “OFF order”.
• The unit will continue running as long as no type-A alarms appear (see section "34.3. Failure
list", for details about type A alarms).
Only extraction Continuous run
with the supply air fan being stopped while the extract air fan will:
a) follow the “normal” set point if the unit was running at “normal speed” or “reduced speed”
before the activation of the fire function
b) follow the “extra” set point if the unit was running at “extra speed” before the activation of the
fire function
• The unit will continue running no matter any other alarm appears (no unit autoprotection).
Only supply
(by default) Continuous run
with the supply air fan running at 100% and the extract air fan being stopped.
• The unit will continue running no matter any other alarm appears (no unit autoprotection).
Stop extraction
and supply Unit stopped.
In all cases, upon activation of the alarm, the display shows ALARM message. Here’s, how to configure the fire mode
function:
26. SMOKE MODE
It is possible to assign a digital input to the SMOKE MODE function. After receiving the signal from an external smoke
control unit, a predetermined behavior of the heat recovery unit fans will be forced.
Input signal type: Voltage-free contact.
SLIM control panel is supplied with a bridge to avoid the appearance of the alarm (contact open = Alarm) See section
"14.2. Corrigo controllers", and check “CONTROLLER 1” wiring diagram for details. As you can see, Smoke Alarm input
is placed in terminals
+C1 & 24 . It is possible to look for this information in section "14.3.5. Inputs & Outputs", too.
When the alarm is activated (contact open), the unit will follow the only extraction strategie (see section "25. FIRE
MODE", for further details). This strategie will be active as long as the contact remains open, no matter if any alarm is
active (no unit autoprotection).
