Switch-Off : turn setting knob to the left; a click will
inform you that the device is OFF.
3 - Lowering input
Your thermostat is fitted an input for set point
reduction that lowers automatically the desired
temperature.
• No signal on input = the thermostat operates
according to the temperature setting.
• 230V signal on input = the thermostat uses a
"reduced" setting corresponding to the temperature
set at -3,5 °C.
4 - Operating modes
Select the desired operating mode by using the switch :
• Automatic mode : it is the
normal operating mode of your
thermostat. Your thermostat
controls the room temperature
based on the set point used.
Operation LEDs indicate the
current set point used :
{
• ON : frost-protection set point
• Blinking : OFF (load shedding)
• ON : reduced set point
{
• ON : comfort set point
• Blinking : Eco 1/Eco 2 set point

• Permanent comfort mode :
your thermostat controls the
room temperature based on
current set point only and
ignores information from time
switch.
• Permanent reduced mode :

• Frost-protectionmode :
your thermostat keeps your
home at a minimum inside
temperature of 7,5 °C.
Use it only when for a period of
a few days or when you air the
rooms.
5 - Locking of controls
You may limit the temperature adjustment range
by using a mechanical blocking (for instance, 17 -
23 °C range).
• Remove the setting knob.
• Remove the small pins from their support.
• Place them so as to define the

Example :temperature can vary
between 17 °C and 23 °C

Adjustments/settings
The settings below are to be done on back of
thermostat. To have access to the back, pull up
thermostat front face and remove it from its base.
a) Installation type
The switch 5 allows to select the value of the
reduced setting.
1 = lowering by 2 °C (suitable for installations
with high inertia, e.g. heating floor).
2 = lowering by 3,5 °C (suitable for installations with
no inertia).
b) Thermostat calibration
The potentiometer 6 is used to adjust the value
measured by thermostat (within a limit of +/- 3 °C).
- Measure the room temperature using a reference
thermometer placed in room centre.
- Check the temperature recorded against that
indicated by the thermostat.
• for instance, if the recorded temperature exceeds
the thermostat temperature by 1 °C, set the
potentiometer to -1.
• Or, if the recorded temperature is below the thermostat
temperature by 1 °C, set the potentiometer to +1 °C.
c) activating/deactivating operating leds

the
thermostat leds. ON = leds are actives
OFF = leds are inactives. It only switches on
temporarily after acting upon the setting knob when

This electronic room thermostat is especially
designed for commercial premises and offices.
The room temperature can be set at the back of the
device within +/- 3°C limits.
Its input for set point reduction allows to connect
it to a time switch to provide additional savings,
for instance by automatically lowering room
temperature at night.
st
"1
Temperature Rise" Mode
This feature allows you to raise the temperature of your
heating floor gradually to limit the thermal stress of the
slab in the cold season and prevent damage to your
installation (cracks in slab...).
• Switch ON and OFF the thermostat thrice quickly
to activate this feature (it should take less than 5
sec) and put the temperature setting knob on room
temperature setpoint on cycle end.
• Thermostat's LEDs will blink slowly one after the
other to indicate that you are in «1st Temperature
Rise» mode.
• After 7 days, the thermostat will exit automatically
st
the "1
Temperature Rise" mode and control
temperature normally. If the thermostat is powered
off during this time (e.g. due to mains power failure),
st
the "1
Temperature Rise" program will resume from
the point it had stopped when the power is restored
(please do not change the thermostat setting).
st
Note : to stop the 1
Temperature Rise cycle, just
switch off your thermostat.
Where and how to install your
electronic thermostat?
The room thermostat must be installed at approximately
1,5 metre up from floor upon an interior wall, away
from direct solar radiation and any heat source such as
television, lighting and air draught etc.
The thermostat is made of two parts :
• a plug-in front face (b).
• A base to be fitted inside a Ø 60 mm flushmounted
box (a).
a) fix the base of your thermostat in a Ø 60 mm
flushmounted box using 2 screws.
a a
b
b) the front face is just clipped onto the flushmounted
assembly.
Note : to prevent parasitic air draughts, it is
recommended to block the electrical supply cable with
an insulatin material (glass wool etc.).
Electrical equipment may only be installed and
assembled by a qualified electrician in accordance
with the relevant installation standards, guidelines,
regulations, directives, safety and accident
prevention regulations of the country.
