UNTES URTP055 Instructions For Installation, Commisioning, Maintenance And Use page 43

COD DESCRIPTION
E
F10
Failure to ignite flame after 4 attempts
performed by the equipment.
F11 Ill-timed flame
F12
Failure of ignition; not visible.
The count, displayed in the historical
list, indicates whether the heater has
had problems with ignition.
F13
The TER equipment does not accept
the reset command from CPU-SMART
F14 Lack of communication between TER
equipment and CPU for more than 60
seconds
F15
The CPU-SMART PCB sent the igni-
tion signal to the equipment. After 300
seconds, the equipment has not yet lit
the flame.
F16 Generic equipment lockout
F17
Internal malfunction
equipment that does not accept reset
command from CPU-SMART
F20
Activation of safety thermostat STB
F21
Input ID1 open caused by:
NOT USED - Jumped
F30
Fan speed too low in start up phase
- VAG
F31
Fan speed too high in start up phase
- VAG
F32 Fan speed, during operation, outside
minimum and maximum set param-
eters - VAG
F41
Probe NTC1 error, intake air tempera-
ture
F51
The temperature of the air intake probe
NTC1>TH1
F60
Communication error between CPU-
SMART PCB and ModBus network,
SmartControl or SMART.NET
F75 No voltage during operation cycle
(ex- cluding stand-by);
the fault is not visible on remote
control but only counted.
F00
Internal malfunction of CPU-
SMART PCB
REASON
•
Phase and neutral reversed.
•
Grounding wire not connected.
•
Phase-phase connection without neutral.
•
Start-up electrode failed or badly positioned
•
Detection electrode failed or badly positioned
•
Detection electrode that moves or disperses to the
grounding system when hot.
•
Low CO value
TER has finished its 5 reset attempts in the period of
15 minutes.
TER equipment or CPU-SMART PCB broken
safety thermostat lockout at start up
•
No mains gas pressure
•
Live and neutral reversed.
•
No or faulty grounding terminals
•
TER equipment broken
TER equipment broken
of TER
TER equipment broken
•
Excess air temperature due to lack of air circulation
•
Safety thermostat broken or not connected
ID1 - IDC1 jumper missing
Burner fan broken.
FAN electrical cables broken or not connected
Absence of signal from probe or broken probe
•
The minimum heat output of the PCH heater module is
over-sized compared to the heat output required by
the environment.
•
Check the TH1 parameter - air intake set point.
•
ModBus network is disconnected.
•
The address of the PCB is wrong and/or not con-
figured in the ModBus network.
No voltage during operation
Perform a manual reset of the PCB; replace the CPU-
SMART if the problem persists.
