The TEH light oil control and safety pro-
grammer controls and monitors the blown
air burner. Thanks to the programme
managed by the microprocessor, extremely
stable times can be obtained, regardless of
the mains voltage oscillations or the ambient
temperature.
The control and safety programmer is
designed for safe use in low voltage condi-
tions. If the mains voltage falls below the
minimum required value (170 V), the control
programmer deactivates without signalling
any error. As soon as the voltage rises
above 178 V, the programmer restarts auto-
matically.
R - Reset Locked status
signal LED.
RJ45 - Connector for PC connection
(diagnostics, supplied
separately).

Lock and unlock
The control programmer can be locked (put
in anomaly mode) and unlocked (anomaly
removal) through the R button, provided that
the control programmer is powered at the
mains voltage.
Prior to mounting or dismantling the
control programmer, the device must
be at zero voltage.
The control programmer must not be
opened or repaired.
