5.3 Every 12 months

1. For rotary heat exchanger (RX) units, check the brush seals
on the rotary heat exchanger along the perimeter in contact
with the frame:
If necessary, bring the brush seals closer to the exchanger to
ensure good sealing.
2. For RX units, check the tension of the driving belt on the
rotating heat exchanger. If there is no tension or if the belt is
damaged, please, contact the service department for a belt
replacement.
Ideally the heat exchanger should be cleaned using vacuum
cleaner with a soft nozzle to prevent damaging the air
passages in the rotor. Turn the rotor by hand to enable you to
vacuum clean its entire surface. If the heat exchanger is
substantially fouled, it can be blown clean with compressed air.
3 For plate heat exchanger (PX) units:
• Clean the drain pan
• Clean the inside of the bypass. To access the interior of the
bypass it is necessary to force it open, proceed as follows:
place a jumper between terminals IN3 and +12V on the
TAC circuit board. The bypass is now open, regardless of the
temperature conditions.
• Remember to remove the jumper between terminals IN3
and +12V once cleaning of bypass is done.
• Always clean against the direction of the airflow.
• Cleaning must only be done by blowing with compressed
air, vacuum cleaning with a soft nozzle or through
wet cleaning with water and/or solvent. Before you begin
cleaning, cover adjacent functional sections to protect
them. If cleaning solvent is used, do not use solvent that
will corrode aluminium or copper.
4. Fan maintenance:
Check again whether the power supply is shut down and
fans are not running.
5. Check seals on the unit:
Ensure that the side access panels are fully closed and that
the seals are intact. Replace if necessary.

6. Troubleshooting

The TAC control board generates and reports 22 types of alarms.
The alarms are subdivided into auto resetting and non-auto resetting alarms. For the latter, a reset will be
necessary once the problem has been resolved.
For each type of alarm, a full text description will be displayed on the user interface depending on the alarm type, together with
a symbol indicating its level:
highest level 3: severe alarm
level 2: warning
information symbol for level 1 and 0: information. Lowest 0 level alarms may be hidden thanks to the parameter «Hide
low level alarms» in Settings/TACtouch setup. Level 0 information have not associated type, so they will not appear in
the description here below.
- Activation of alarm output (see point 4.1, figure 2)
- Activation of pressure alarm output in case of pressure alarm (see point 4.1, figure 3).
- "Alarm" activated LED's on control board
- Alarm on user interface
- Alarm communication with networking modules provided that an optional communication module
(Modbus RTU, MODBUS TCP/IP, and KNX) is installed on the TAC control board.
- In addition, beside the alarms generated by the TAC controller, the TACtouch gives also its own alarm in case of
communication error: "No communication with TAC".
In this case, follow these steps to diagnose the problem until that the communication has been recovered:
- The cable is well connected to TAC board on connector RJ1.
- If an extender cable is used, try to invert the 2 communication wires A+ and B- , and, if there is still no
communication, eventually try with the original cable.
- Upgrade to last version (instruction manual and last version are available on Swegon web site).
- Configuration check: Go in menu Settings/TACtouch and check that Parameter "TACtouch master" =
"No" and Parameter "Slave Address" = "2". This is the default configuration, however, for installation
where the TACtouch is master for the communication or where it has to use a specific address as slave,
then enter the correct values for the corresponding parameters.
- Check that the contacts of the green connector at TACtouch back cover are well screwed.
- Replace the TACtouch or the control board TAC6: test the communication if possible with another
TACtouch, or, in alternative, with TACsimulator software and adapter cable connected to RJ1 (see
dedicated sheet in user wiring diagram on web site). Check that the communication is correct, if yes,
the problem was linked to the original TACtouch which would need to be replaced, otherwise, so still no
communication, then the control board TAC6 has to be replaced.
