IV.15. Fire protection function
Refer to parameter settings in section V.8
There are 2 ways to manage the fire safety function:
Firefighter shutdown: To be wired between terminals 1 and 2 (volt-free NC contact). Total shutdown of the system control.
•
(plus no selections available)
Fire alarm: This function allows the supply and recovery fans to be controlled in accordance with the 5 modes available
•
in the control parameters (this function can be enabled in the parameters). An alarm appears on the «Fire alarm»
screen
1.
“Shutdown”:
Total system shutdown
2.
“Continuous operation”:
Startup or maintenance of unit operation in HS mode. The fire protection function will
have priority over all other alarms.
3.
“Normal operation”:
System operation maintained in accordance with parameters defined on site
(Shutdown/LS/HS)
4.
“Blower fan only”:
Startup or maintenance of the blower fan in HS operation (restart on shutdown)
5.
“Recovery fan only”:
Startup or maintenance of the blower fan in HS operation (blowing on shutdown).
The digital input “Ext. shutdown” has priority over the fire safety function.
This function is not suitable for the French market and, in any case, must be approved by an authorised inspection
body.
The digital fire alarm input must be connected across terminals
DI8 of the controller and 13 of the terminal block (voltage-
free contact mandatory)
IV.16. Dehumidification function
Refer to parameter settings in section V.8
It is possible to associate with the system a COMBIBOX CONCEPT
®
module: cooling coil (water or cooling-only DX), followed
by a heater battery (water, electric or DX heater). In this case the controller will automatically control the heat/cold ratio
required for dehumidification, while maintaining a optimal operating temperature. During a request for cooling, temperature
control has priority over dehumidification.
Connect the coils/batteries as indicated sections IV.12 to IV.14
Position the humidity sensor in the ducting at the point of supply or recovery, according to your humidity control mode.
Connect the humidity sensor as follows
