  • As an accessory, filter replacement kit with G4 filters (coarse 65%) at extraction and F7 (ePM1 60%) on the air inlet.

TAC5 DM control unit ready to connect
  • Complete regulation allowing 3 operating modes:
SETTING THE FLOW RATES RECOMMENDED APPLICATIONS
LS MODE - VARIABLE FLOW RATE
Fan speed variation by 0-10V signal
Flow rate setpoint according to a 0-10 V signal from an external sensor (CO2, temperature, hygrometry, etc.). Single-zone installations, requiring adaptation of ventilation according to occupancy
AC MODE - CONSTANT FLOW
Fan speeds defined according to a precise flow rate
3 maximum constant flow setpoints, input of values with reading on display.
Switching between the different setpoints carried out manually from the remote control or automatically by clock (not supplied) or presence detection.
Installations requiring the control of one or more precise flow rates.
CPs MODE - CONSTANT PRESSURE
Automatic variation of fan speed to maintain constant pressure
Flow automatically modulated in order to maintain a constant pressure value measured by an external probe (pressure probe as an accessory). Multi-zone ventilation systems, associated with modulation of terminal airflows.

  • The operation of the exhaust fan is slaved to the supply fan. Its flow rate corresponds to a percentage of the flow rate of the supply fan (generally 100%).

Regulation accessories
  • HMI TACtouch 4.3 ”touchscreen, IP20, for parameter setting, control, visualization.
  • SAT3
    • Signals the actual operation of the fan via a potential-free contact (relay normally open) (relay R3)
    • Ex: authorization of operation of an external battery (post-ventilation function that can be programmed).
    • Signals the alarm on a pressure variation (relay R2).
  • SAT TAC5 BA / KW
    • Modulates the power of the batteries in order to maintain the supply temperature equal to the setpoint.
    • Provides antifreeze protection for water coils.
    • Gives a control contact for the circulator.
    • Manages the hot / cold passage via a digital input.
    • Allows the batteries to be switched off via a digital input.
