2. Wire connections
3. Connectiong temperature sensor wire
Connect the temperature sensor wires to the sensor terminals located at the
back of the thermostat (no polarity needs to be respected).
Note
: Do not place the sensor probe directly next to an element but rather, for
maximum performances, the sensor probe should be centered between the wires
in the mat (80 °C max.). The temperature sensor wire cannot lay across any
heater wires.
Adjusting the floor’s maximum temperature
When the floor sensor is installed, the temperature of the floor will automati-
cally be limited the set maximum regardless of the ambient setpoint. To adjust
the floor’s maximum temperature, press on the adjustment button (see drawing
for its position) using a pointed object, and use the and buttons until the
desired setpoint appears.
4. Configuration of switches
a)Early Start function
The thermostat is providing a built- in function enabling it to
calculate the optimum time to start the heating system to achi-
eve the desired temperature setting at the programmed time. To
enable this function, set the switch E.S. (#1) to “ON”.
b)Temperature in °C or °F
The default configuration of the
DTW16S
is in °C. If you wish to
change the temperature to °F, push the switch #2 upward.
Please note that if you change from °C to °F, your Comfort and
Economy settings will need to be reconfigured as well.
POWER—UP
When power is applied for the first time, the
display must show the time 0:00, the floor tem-
perature and the Manual mode icon ( ). Other
information might show up on the display if
installation is defective or does not comply with
the instructions.
The message L0 or HI will appear on the dis-
play if the temperature sensor is defective or the
temperature is below 0 °C or higher than 60 °C.
Also, if the LO message is displayed, the heating
indicator will be present on display and the relay
will be closed (current going in the load).

Schedule programming
The DTW16S allows 4 setting changes for each day of the week. There are no
pre- set programs. The programs are tailored to perfectly adapt to your life style.
The principle is very simple. For each day, enter the time at which you wake up
(P1), the time you leave for work (P2), the time you arrive back home (P3) and
the time you go to bed (P4).
For savings to be obtained, you must lower the temperature for a period of at
least 2 times the delay required to bring the temperature back to your comfort
level.
Example
: If your system takes one hour to go from your saving temperature level
to your comfort temperature level, it is useless to lower the temperature for a
period less than 2 hours.
