Introduction
I Description of the product
Intended and unintended use
The Elro programmable room thermo-
stat KT100 is a fully automatic thermo-
stat with a total of 20 programs. The
thermostat is intended for controlling a
heating or cooling system suitable to be
switched. Any other use than the intend-
ed use described above is considered
unintended use. Elro cannot be held lia-
ble for any damage caused by improper,
incorrect or unwise use.
Operation
The thermostat operates on the basis
of a comfort, economical and frost pro-
tection temperature. You can set the
temperatures manually use preset
programs. The thermostat ensures a
comfortable temperature and can be
adjusted to your needs. By using the
economical temperature, your heating
is automatically set to a lower setting at
desired times to save energy. The ther-
mostat is only suitable for indoor use.
The thermostat should be connected
to a suitable heating or cooling system.
The proper operation of the thermostat
and control of the temperature depends
on the correct functioning of the con-
nected heating or cooling system.
This manual is intended for the user of
the thermostat. Read the manual care-
fully and keep it for later reference.

1 Precautions and safety instructions
Warning! Always disconnect the
power from the device to which the
thermostat will be connected during
installation and disassembly. This
prevents an electric shock and damage
to the equipment.
Warning! Ensure that there are
no water/gas pipes or electrical wires
in the wall at the spot where you mount
the thermostat. When in doubt, use a
pipe detector to make sure you are not
drilling in a pipe.
Warning! The thermostat is for
indoor use. The thermostat may not
become wet.
Warning! Do not use a pencil for
resetting the thermostat with the “reset”
function. The graphite in the pencil can
cause a short circuit and consequently
cause damage to the thermostat.
Attention! When using the “reset”
function all settings are returned to the
original factory settings. This means
that you will lose your manually set
programs and presets. You cannot
retrieve it.

3 Assembly and installation
To assemble and install the thermostat,
follow the steps below:
• Hold the template against the
spot where you want to install the
thermostat. Use the cross marks on
the template to drill two holes in the
wall. Use a drill of 6 mm
4
• Insert the plugs into the holes
5
.
• Lead the two wire cable (these come
from the device to be connected)
with the green terminal block at the
back of the thermostat
6
. In most
cases these are the connections “NO”
and “COM”. Refer to the manual of
the heating or cooling system to be
connected.
• Insert a screw into the left plug. Make
sure it protrudes approximately 5 mm.
Place the thermostat on the screw
and slide it to the right. Insert the
other screw into the right plug through
the battery holder
7
.
• Place the batteries
8
.
4 Operation of the thermostat
4.1 Setting the time
Choose the day of the week with “day”
(5). Choose the time in hours with
“hour” (6) and the time in minutes with
“min” (7).
Tip! Press and hold any key for
more than 2 seconds to change the
time rapidly. Release the key when the
desired time is reached.
4.2 Setting the temperature
The thermostat works on the basis of
three temperature settings:
: Comfort temperature. This is the
temperature that you use for your per-
sonal comfort.
: Economic temperature. This is the
temperature that you use to save ener-
gy, for example, when you are not at
home or when you are sleeping.
: Frost Protection Temperature. This
temperature is 7°C and you cannot
change it.
You can adjust the comfort and eco-
nomic temperature from 5 thru 30°C
as desired. The set temperature is
then maintained within the selected
programs.
Set the temperature as follows:

as desired. The set temperature is
then maintained within the selected
programs.
Set the temperature as follows:
• Press “temp” (8) and then press
(3) or (4) (depending on whether
you want to change the comfort or
economic temperature). Each time
you press or , the temperature
increases by 0.5°C. Store the values
with “ok” (14). If you want to select
a temperature lower than the set
temperature: keep pressing or
. Once the setting exceeds 30°C, it
return to 5°C.
Tip! Press and hold any key for
more than 2 seconds to change the
chosen temperature rapidly. Release
the key when the desired temperature
is reached.
4.3 Choosing programs
3
The set comfort and economic tem-
perature are implemented by the ther-
mostat on the basis of a program. You
can choose from 10 preset programs (0
thru9)and10programsthatyoucan
modifytoyourpreference(10thru19).
You can set a program per day of the
week.Press“prog”(9)inordertoview
the selected program per day. A pro-
gramconsistsofaprogramprolewith
24 blocks of one hour. Per hour, either
the comfort temperature is enabled
(dash) (B) or the economic enabled (no
dash) (A).
To choose a program for a day of the
week, take the steps below:
• Press“prog”(9)
• Thenrepeatedlypress“prog”(9)
until you are on the day of the week
for which you want to choose the
program.
• Then repeatedly press “prog #” (10)
until you have reached the desired
program. Exit with “ok” (14).
The thermostat is set to program 1 by
default. In this program the comfort
temperature is maintained from 06:00
0504_ELRO_KT100 thermostat_CH_130x73_2.indd 7 07-09-12 15:32

8
until 23:00. The economic tempera-
ture is maintained between 23:00 and
06:00. Program 0 is the frost protec-
tion program. Here, the entire day and
night the frost protection temperature is
maintained.
4.4 Modifying programs
• To modify a program, follow the steps
below:
• Press“prog”(9)
• Thenrepeatedlypress“prog”(9)
until you are on the day of the week
for which you want to choose the
program(modicationisonlypossible
ofprogram10thru19).
• Runthroughtheprogramprole
(21) of that day of the week (starting
at 00: 00 hours) in order to modify
the program. If you want comfort
temperature on a block of time,
press (3). If you want economic
temperature on a block of time, press
(4). After the choice between
comfort and economic temperature
you automatically continue to the next
blockoftime.Onceyouaresatised
withtheprogramproleoftheday,
exit with “ok” (14).
4.5 Temporarily deviating from a
program
You can deviate from a program by
selecting the opposite mode. For exam-
ple: The program has set the thermo-
stat to economic temperature. But you
temporarily want a higher temperature.
Press (3). The thermostat temporar-
ily switches to comfort temperature. The
thermostat returns to the programmed
setting by pressing “ok” (14), or when a
new hour begins.
To deviate from a program for more than
an hour, press and hold (3) for 2 sec-
onds. Press again to change the time
of the deviation. Up to 24 hours may be
deviated from the program. The thermo-
stat then automatically switches back in
the programmed temperature. To devi-
ate from the comfort temperature follow
the same actions, but instead press .
4.6 Other settings
The function “CL/HT”
The thermostat can be connected to
a heating system or a cooling system.
The thermostat should be set on “HT”
for a heating system and on “CL” for a
cooling system. If necessary, adjust the
setting by pressing “mode” (15). Then
press “CL/HT” (13) until the desired
mode appears. Exit with “ok” (14).
The function “DLY”
The thermostat optionally can start your
heating system delayed (for a cooling
system, this is set by default). The ther-
mostat only starts your system after it
has been switched off for 5 minutes.
Presson“mode”(15)rsttoenable
the delay. Then press “DLY” (12) until
“DLY” appears on the display and exit
with “ok” (14). To turn off the delay, fol-
low the same procedure but make
sure that “DLY” is not shown in the dis-
play.
The function “1C/2C”
You can set the permissible temperature
uctuationor“span”.Thespandeter-
mines how much the ambient tempera-
ture may increase or decrease before
the thermostat responds. For example:
with a span of 1°C and a comfort tem-
perature set to 20°C, the temperature
maydecreasetoamaximumof19.5°C
(for a heating system) or increase to
20.5°C (for a cooling system) before the
thermostat responds. To set the span,
rstpress“mode”(15)andthenpress
“1C/2C” (11) until you see the desired
span in the display. Exit with “ok” (14).

6.2 Environmental conditions
For a proper operation, the thermo-
stat must be mounted at the correct
spot. Use the thermostat only indoors
anddonotinstallitinamagneticeld.
This can cause damage to the internal
components.
Do not install the thermostat near a heat
source (radiator, TV, fridge), in the sun
or in the draft. It is also not recommend-
ed to mount the thermostat on an out-
side wall or near a window. This affects
the measurement of the temperature.
Mount the thermostat at a height of
approx. 1.65 meter.
