IV.16. Defrost heater battery

The defrost heater batteries are single-phase units on all the models in the range with the exception of the INFINITE BC
series 1800 and 2500, on which are they are three-phase units.

IV.17. Fire protection function

Refer to parameter settings in section V.6.b.6
There are 2 ways to manage the fire safety function :
• Firefighter shutdown : To be wired between terminals 1 and 2 (volt-free NF 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 situ). An alarm appears on the « Fire alarm »
screen
1. "Shutdown": Total system shutdown
2. "Continuous operation": Startup or maintenance of the system in HS operation. 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/PV/GV)
4. "Blower fan only" Startup or maintenance of the blower fan in HS operation (recovery fan stopped)
5. "Recovery fan only" Startup or maintenance of the recovery fan in HS operation (blower fan stopped).
The digital input "Ext shutdown" has priority over the fire protection 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 protection input must be connected across terminals DI8 of the controller and 13 of the terminal
block (voltage-free contact mandatory)

IV.18. Dehumidification function

Refer to parameter settings in section V.6.b.7
It is possible to associate with the system a COMBIBOX CONCEPT
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.
Function not available in DIVA mode
!
Connect the coils/batteries as indicated sections IV.12, IV.14
Position the humidity sensor in the ducting at the point of supply or recovery, according to your humidity control mode.
In the case of ambient humidity control for single flow system with recycling, position an ambient humidity sensor in the
building. This must be installed in a neutral position (where it is not affected by external agents)
Connect the humidity sensor as follows:
