2 Functionalities of the regulation
The TAC4 DG controller is mounted in the units of maxi-series.
The functionalities of this TAC4 DG control board are described in detail in the “Operating
instructions TAC4+RC” manual.
The TAC4 DG control board provides the following functionalities:
•
Control of supply and exhaust fans in constant air flow (CA), constant pressure (CPs) and
constant airflow linked to a 0-10V signal (LS) mode.
•
Management of 6 time slots.
•
Default, set point and pressure alarms.
•
Management of airflows in case of fire alarm.
•
BOOST function that helps to force the supply and exhaust airflows to a value set beforehand-
overriding all configurations and conditions.
•
Automatic management of the 100% bypass for free cooling.
•
Automatic management of the opening and closing of valves mounted on the suction side.
•
Anti-frost protection of the heat recovery exchanger by modulation of the supply airflow or by
regulating the power of the pre-heating electric coil (KWin).
•
Regulation of the post-heating water (NV) or electric (KWout) coils to maintain a constant supply
temperature.
The following options can be combined with the TAC4 DG control board:
•
Option SAT TAC4 BA/KW:
Regulation of 2 external heat exchangers (hot and/or cold).
•
Option RC TAC4:
Local remote control that can be used for the configuration, display and control of the TAC4 unit
to which it is connected.
•
Option SAT3:
Circuit with 2 relays for
- “Fans ON” and “Pressure alarm” signals (if in position O.R.1 / O.R.2)
or
"Circulator control” and “Bypass status signal” (if in position O.R.3 / O.R.4)
