If the level falls below the threshold, the system signals the lack of fuel for a time equal to the
T24
, then it goes in Extinguishing with error (Er18). If the tank is filled the system stops every
signalling and it is possible to restart it.
This control is done only in Pellet modality.

If a Pellet Level Sensor is connected with output in DC and the voltage is greater than 5v, connect it to the
IN8 or IN9 input. These inputs can support voltage until 12V. Sensors with maximum output 5V, can be
connected to every input. The temperature controller can support only Pellet Level sensors PNP type.
Limit Switch Cleaning Engine
Use the contact only if an output is set as Cleaning Engine.
Limit Switch Cleaning Engine 2
Use the contact only if an output is set as Cleaning Engine 2.
Limit Switch Brazier Cleaning Engine
Use the contact only if an output is set as Brazier Cleaning Engine.
External Chrono
At the closure of contact, the system goes in Ignition, at the opening it goes in Extinguishing.
Analog Inputs
Exhaust Probe (Thermocouple)
To the connections 25-26 is available the Exhaust Probe. With this probe, it is possible to read the exhaust
temperature.
This probe is a Thermocouple K sensor. The sensor can read from 0 to 500°C with a precision of 1 °C. If you
don’t connect the probe to the system you’ll read 900 °C.
NOTE: even if the sensor can read temperatures in the range 0 ÷ 500 °C the entire sensor wiring can work
only in the range 0 ÷ 500 °C.
TiEmme elettronica is not responsible of any damage or bad functioning of the probe due to a wrong use of
it (i.e. thermic and mechanical stresses to the probe).
Boiler Probe
To the connections 31-32 is available the Boiler Probe. With this probe, it is possible to read the water
temperature of the boiler. If you don’t connect the probe to the system you’ll read -50 °C, in case of short-
circuit you’ll read the maximum value.
Buffer Probe / Top Buffer Probe
To use this input as a Probe set the parameter
P26
=4, 8, 10, 11 and
P74
,
P75
or
P76
=9.
This probe is a NTC 10K sensor; it can read from -50 to 110°C with a precision of 1 °C. If you don’t connect
the probe to the system you’ll read -50 °C. In case of short-circuit you’ll read 110 °C.
Bottom Buffer Probe
To use this input as a Probe set the parameter
P26
=4, 8, 10, 11 and
P74
,
P75
or
P76
=23.
If you don’t connect the probe to the system you’ll read -50 °C. In case of short-circuit you’ll read 110 °C.
Boiler Return Probe / Flow
To use this input as a Probe set the parameter
P26
=7, 8, 9 and
P74
,
P75
or
P76
=8.
This probe is an NTC 10K sensor and its range is -50÷110 °C with a precision of 1 °C. If you don’t connect
the probe to the system you’ll read -50 °C, in case of short-circuit you’ll read 110°C.
