THIS MANUAL HAS BEEN MADE WITH GREATEST CARE.
HOWEVER, NO RIGHTS CAN BE DERIVED THEREFROM. WE RESERVE THE RIGHT AT ANY TIME
TO PARTIALLY OR ENTIRELY CHANGE THE CONTENT OF THIS MANUAL WITHOUT PRIOR
NOTICE.
This manual contains all the best for an assembly plant and a heat recovery unit (HRU) necessary
information. The manual also serves as a handbook for installation, maintenance and customer service
work. We recommend that any intervention in the appliance installation company should be consulted.
Subject of this operating manual is the control unit TAC4 with the operating unit GRC TAC4. Possible
accessories are only described insofar as it is necessary for the appropriate operation. Please see the
particular manuals for further information on accessories.
If you have any questions that have not been answered or have not been sufficiently answered in this
documentation, please contact the company Paul Wärmerückgewinnung GmbH. We will be glad to help
you.
1 Introduction
Safety
1.1
Please always observe the safety instructions in this operating manual. The non-observance of the safety
instructions, warning notices, notes and instructions can lead to injuries or damages to the maxi.
•Unless otherwise stated in this operating manual, only an authorised installer is entitled to install,
connect, put into operation and maintain the maxi;
•The installation of the maxi is to be performed according to the general local building, safety and
installation instructions of the corresponding local authorities, of the water works and electric
works and other official regulations and directives;
•Always follow the safety instructions, warning notices, notes and instructions described in this
operating manual;
•Please keep this manual during the complete life time of the maxi in proximity to the device;
•The instructions for the regular replacement of the filters or the cleaning of the supply and exhaust
air valves are to be strictly followed;
•The specifications stated in this document may not be changed;
•Any modification of the maxi is prohibited;
•In order to guarantee that the device will be regularly controlled, it is recommended to conclude a
maintenance contract. Your supplier can give you the addresses of authorised installers in your
area.
Used symbols
1.1.1
The following symbols are used in this manual:
Caution, special note!
Risk of: - injury of the user or the installer
- damages to the device
- impairment of the operation of the device if the instructions are not
carried out properly

2 Functionalities of the regulation
The TAC4 DG controller is mounted in the units of maxi-series.
This handbook describes the functionalities of the TAC4 DG when using a GRC TAC4 display. A
SAT MODBUS satellite (option) is used to connect the graphic remote control (GRC).
The TAC4 DG with GRC 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. CO2 sensor).
•Management of 6 timeslots.
•Alarms on defects, set points, overpressure.
•Fire alarm airflow management.
•BOOST function, allowing to force a pre-set airflow (supply/exhaust), overriding the assigned
airflow
•Automatic management of the 100% bypass to allow free cooling.
•Automatic management of inlet dampers (CT).
•Heat exchanger antifreeze protection system by modulation of airflow or with an intelligent pre-
heat electrical coil (KWin).
•Post heating management of water coil (NV) or electrical coil (KWout) battery to keep a set
temperature constant.
The following options can be combined with TAC4 DG controller:
•SAT TAC4 BA/KW Option:
Regulation of 2 external heat exchangers (electrical/water, hot and/or cold).
•SAT TAC4 MODBUS Option:
MODBUS RTU communication (please refer to TAC4 DG - MODBUS RTU installation and user’s
manual for detailed information).

To allow easier identification of the temperature sensors 4 different wire colors are used:
-T1 : black wire
-T2 : white wire
-T3 : blue wire
-T4 & T5 : green wire (not at maxi flat-series)

4 GRC wiring and funtionalites
The regulation is delivered fully factory pre-wired. Nevertheless, the TAC4 GRC (graphic remote control)
and the i/o signals if any must still be wired by the installer.
Installation of GRC
4.1
The GRC is designed for indoor use. For outdoor application, use a weatherproof
housing.
All the configuration data is enclosed in the TAC4 DG circuit. It is thus possible to
remove the GRC without disrupting the installation.
The GRC is delivered with attachments and fastening screws. Mounting panel thickness should not
exceed 5mm. The rectangular indent in mounting panel is 147x82mm.

On wall installation
4.1.1
This kit GRC includes a box with an opening in the lid where the GRC touchscreen fits perfectly.
Fix the GRC in the lid with the mounting brackets supplied in the GRC kit GRC.
The cable entry holes in the box will have to be done by the installer.
In wall installation
4.1.2
This kit GRC allows the touchscreen GRC to be flush mounted in a wall. It includes a box and a stainless
steel front panel on which the GRC can be fixed.
