elitec AUT-S
On/Off Thermostat
Installation manual
PLEASE READ THIS MANUAL CAREFULLY BEFORE
INSTALLATION, AND STORE WITH OTHER WARRANTEE
FORMS.
The elitec AUT-S is an electronic thermostat with four
functions: Room sensor, floor sensor, power regulator and
room sensor with max./min. limiter. Setback temperature fixed
3°C via external time switch
1. Startup
Remove the adjustment wheel with a screwdriver. The front cover
can the be removed by pushing in the locking clips on each side
of the thermostat (as shown in fig.2). Be careful when doing this
in order not to damage the thermostat. When the thermostat
has been connected to the power source, push the on/off
button. Never dismantle the thermostat cover when the power is
switched on.
2. Sensor choice
When choosing a sensor type, the thermostat should not be
connected to a power source.
• Floor sensor (standard)
Jumper placement: Covering the two pins on the left.
Application: The temperature is regulated by the floor sensor.
• Room sensor
Jumper placement: Covering the two pins in the right
Application: The temperature is regulated by the room sensor.
• Room sensor with limiter
Jumper placement: Covering the two pins on the right + the
floor sensor connected
Application: The temperature is regulated by the room sensor,
but the floor sensor overrides the room sensor if the floor
temperature exceeds the maximum limit temperature. The limiter
can be regulated between 20°C and 30°C. For parquet flooring, a
maximum of 27°C is recommended by most flooring manufac-
turers. Please follow the recommendations provided by your
manufacturer.
• Power regulator
Jumper placement: Covering the two center pins
Application: The effect regulator has a 30 min cycle. The desired
on/off interval can be set from 0 to 10, where each level increases
the on-time by 3 minutes.
Example: When the thermostat is set to level 3, the heating
element is switched on for 9 minutes, then off for 21 minutes in
the 30 minute cycle. If the thermostat is set to level 6, the heating
element is switched on for 18 minutes, then off for 12 minutes.

3. Connecting the thermostat
Bi-LED diode
The thermostat must be connected to the power source according to
Adjustment wheel
the connection diagram. All heating systems must be equipped with
a residual current disrupter with 30mA. Max load for the thermostat is
16A/3600W at 230V. If the load is higher, the thermostat must be con-
nected to a contactor. The thermostat does not have galvanic insulation
between high and low current. The sensor must therefore be considered
as live (230V) and needs to be installed in accordance with the rules for
high current installations and national installation requirements.

Caution: When reattaching the thermostat cover, make sure the ventila-
tion on the top and bottom of the thermostat is not covered up.

The AUT-S does not have a built-in setback temperature option, but by
connecting an external timer to the S and L clamps, the temperature can
be lowered by 3°C at desired times.

5. Calibrating the temperature

When connecting the floor heating system for the first time, the tem-
Adjustment wheel
perature should be set at a maximum of 15°C to 20°C. The thermostat
Fig.2
should be calibrated after 2-3 days. Pull out the adjustment wheel

carefully (without turning it) until it comes loose. Use a thermometer to
check the actual temperature, and push the adjustment wheel back onto
the thermometer in accordance with the measured temperature. If the
floor heating has been switched off during the summer, this procedure
should be repeated when it is switched back on.

• Green light when the thermostat is in a standby mode.
• Constant red light when the relay is engaged and the power is on.
• Blinking red light when there is a sensor malfunction or the floor
sensor is disconnected.
