    1. FUNCTIONALITIES OF THE REGULATION The TAC4 DG controller is mounted in the units of series HRglobal, HRup and HRflat. This handbook describes the functionalities of the TAC4 DG when using an RC TAC4 display. The TAC4 DG with RC TAC4 controller provides the following features: Monitoring of the fans (exhaust and supply) in chosen working mode: constant airflow (CA), constant pressure (CPs) or constant airflow linked to 0-10V signal (LS) (e.g.

    Installation and user’s manual TAC4 DG + RC 3.14. Fan failure alarm It is possible with a SAT3 mounted on the TAC4 DG (option) to provide the fan status (control if actual delivered airflow > 20% of airflow assignment) or if they are stopped, using the R3 relay of one of the SAT3 (O.R.2). This feature provides an increased safety with regard to the start instruction control, because there is a control on the fact that the fan is actually running (closed loop principle).

    3.15. Actual airflow / pressure output signals A 0-10V signal representing the actual airflow or the actual pressure delivered by one of the selected fans with a linear relation is a standard feature. The output signals are located between terminals OUT1/OUT2 and GND on the TAC4 DG circuit. Default setup: OUT1 = airflow fan 1 (supply fan) and OUT2 = pressure fan 1 (supply fan).
