Display and Condensate Error Checklist
ERROR
REMEDY
PV displayed as flashing UUUU
Printer turned off or not initialized.
Temperature Sensor Loom between Printer and
TCM disconnected. Check connections.
SV not reached within 40
minutes.
PV not maintained within +/- 1°C
of SV.
Check that the Printer side safety covers are fitted.
Check/replace TCM discharge filter.
Check Air In and Air Return ducting is correctly
fitted.
Check all Printer covers are fitted and closed.
Check Controller PV is not displayed as UUUU (see
above).
Check SV is set to a value within +/- 8°C of ambient
temperature.
Check ACU condenser grills are not blocked or
obstructed.
No beacon and/or Controller display (see electrical
faults section).
TCM fails to move PV towards SV. Possible fault
with ACU, Heater, or Control Module. ESCALATE
Check supply voltage has not dropped below 207V
ErEP displayed on Controller
Possible anomaly of the Controllers EPROM
memory. Press the P key.
Blue and Red Beacon
(TCM Shutdown)
Condensate Container Full and approaching
Overflow condition. Empty Condensate Container.
Condensate on Lower Tray. Drain condensate from
tray and ensure Condensate Container is in place,
drip tray plug is removed, and container is not
leaking.
