The THL105 is a compact field mount thermostat for regulating heating cables and ribbons, allowing control of resistive
load up to 3.5 kilowatts. The digital regulation allows to combine precision and ease of use.
Temperature and setpoint are displayed on a large LCD display.
Technical specifications can be downloaded at: http://www.loreme.fr/fichtech/THL105_eng.pdf

160°C out: off Temperature and output relay state.
SET point:140°C Setpoint.
The push buttons allow a direct adjustment of the setpoint. The button allows you to increment the setpoint and the 
button to decrement it. The setpoint is incremented or decremented in steps of 1 °C at the beginning. Holding pressed
the or button for more than 4 s will increment or decrement the setpoint in 10 °C steps.
Configuration
An advanced configuration is accessible via the 'Config' button. The user can thus configure the hysteresis and delay
parameters of the regulation.
The regulation works as follows:
- The load is energized when the temperature drops below the setpoint and after the configured delay time.
- The load is no longer supplied when the temperature goes above the threshold plus the hysteresis.

1) Method
In configuration, different types of questions are asked. For each of them, several answers are possible. Here is their
description:
1.1) Value acquisition
Example: SEUIL?
80 °C
Two possibilities:
- The validation without modification by typing "Enter",
- The modification with simultaneous display followed by validation with "Enter" key.
2) Configurable parameters
The following parameters can be configured:
- The threshold (setpoint).
- The hysteresis.
- The delay.
2.1) Configuration messages
CONFIGURATION
REV:0.1
SEUIL? Threshold setting (-50 °C to 250 °C).
80 °C
HYSTERESIS? Hysteresis setting (0 °C to 50 °C).
2 °C
RETARD? Relay activation delay setting (0 s to 300 s).

Remarks:
- It is possible, when a mistake is made during a value acquisition, before validating it, to go back by pressing on
backspace key. This re-displays the message without taking notice of the mistake.
- In configuration mode, if there is no action on a key during 2 minutes, device goes back in measure mode without
taking notice of the modifications made before.
- In configuration mode, if you want go back to measure mode without taking notice of modifications made before,
just press the escape key.

Sometimes, it may be interesting to modify the measure by a simple terminal keyboard intervention. It can be used in
many situations as sensor aging, an input refinement as a result of magnifying effect...
To shift the measure, it is necessary:
- To be in measure mode,
- type on "+" or "-" to access the function,
- on terminal display become:
138.5 Ohms
100.5 °C Temperature value with offset,
OFFSET 0.5 offset function, temperature offset value.
- Use keys "+" and "-" to adjust offset, the temperature is directly modified.
- Type on "Enter" to save the new offset.
OFFSET
When the device is powered off and on, the offset stays active. To reset offset, it is necessary to enter in "OFFSET"
mode, put the value to zero by "+" and "-" keys, then validate by <ENTER>.
In offset mode, when there is no action on a key during 120 s, the device leaves automatically the mode and discard the
new adjusted offset value and keeps the old offset value.

1) Introduction
To meet its policy concerning EMC, based on the Community directives 2014/30/EU & 2014/35/EU, the
LOREME company takes into account the standards relative to this directives from the very start of the con-
ception of each product.
The set of tests performed on the devices, designed to work in an industrial environment, are made in accor-
dance with IEC 61000-6-4 and IEC 61000-6-2 standards in order to establish the EU declaration of confor-
mity. The devices being in certain typical configurations during the tests, it is impossible to guarantee the re-
sults in every possible configurations. To ensure optimum operation of each device, it would be judicious to
comply with several recommendations of use.
2) Recommendations of use
2.1 ) General remarks
- Comply with the recommendations of assembly indicated in the technical sheet (direction of assembly,
spacing between the devices, ...).
- Comply with the recommendations of use indicated in the technical sheet (temperature range, protection
index).
- Avoid dust and excessive humidity, corrosive gas, considerable sources of heat.
- Avoid disturbed environments and disruptive phenomena or elements.
- If possible, group together the instrumentation devices in a zone separated from the power and relay cir-
cuits.
- Avoid the direct proximity with considerable power distance switches, contactors, relays, thyristor power
groups, ...
- Do not get closer within fifty centimeters of a device with a transmitter (walkie-talkie) of a power of 5 W, be-
cause the latter can create a field with an intensity higher than 10 V/M for a distance fewer than 50 cm.
2.2 ) Power supply
- Comply with the features indicated in the technical sheet (power supply voltage, frequency, allowance of the
values, stability, variations ...).
- It is better that the power supply should come from a system with section switches equipped with fuses for
the instrumentation element and that the power supply line be the most direct possible from the section
switch.
- Avoid using this power supply for the control of relays, of contactors, of electrogates, ...
- If the switching of thyristor statical groups, of engines, of speed variator, ... causes strong interferences on
the power supply circuit, it would be necessary to put an insulation transformer especially intended for instru-
mentation linking the screen to earth.
- It is also important that the installation should have a good earth system and it is better that the voltage in
relation to the neutral should not exceed 1V, and the resistance be inferior to 6 ohms.
- If the installation is near high frequency generators or installations of arc welding, it is better to put suitable
section filters.
2.3 ) Inputs / Outputs
- In harsh conditions, it is advisable to use sheathed and twisted cables whose ground braid will be linked to
the earth at a single point.
- It is advisable to separate the input / output lines from the power supply lines in order to avoid the coupling
phenomena.
- It is also advisable to limit the lengths of data cables as much as possible.
