Thermostat
The thermostat must be installed on a DIN standard rail (EN 50022-35) in a
normskåp with the applicable encapsulation class. The thermostat is IP20 classed
and intended for installation in environments with a temperature range of -20 °C
to +45 °C.
The thermostat has 14 terminal blocks numbered according to the wiring
diagram below:
Sensor
If the thermostat is going to be used as a oor heating thermostat, connect the
room sensor as A, and the oor sensor as B. If you are installing a oor that requires
over heating protection, connect the room sensor as A and the over heating
protection as B.
Install the oor sensor in a spiral tube recessed in the oor. The end of the tube
must be sealed to facilitate possible replacement of the sensor.
Place the room sensor so that it is not exposed to direct sunlight or draught. If the
room sensor is installed in an appliance box, it must be sealed to prevent the air
temperature being aected by draught.
For other types of operation and control, the temperature sensor can be installed
as either A, B or A+B. For operation type max/min, the moisture sensor can also be
installed as sensor C. You give the location of the sensor in the START MENU. The
high temperature sensor is recommended for temperatures above +75 °C. Only
one high temperature sensor can be connected. It must always be connected as
B, terminal block 7 and 8.
Installation
The incoming phase and
neutral are connected to
terminals 1 and 2.
Terminals 3 and 4 are the relay
that regulates the load.
Sensor A is connected to
5 and 6.
Sensor B is connected to
7 and 8.
A possible external alarm
is connected to terminals

INDUSTRY
Operation mode INDUSTRY is used to regulate the
temperature of industrial processes, high temperatures
or for the frost protection of sensitive installations.
Temperatures within the ranges -15 °C to +75 °C and
0 °C to +170 °C can be regulated in this mode or the
range can be limited to between -10 °C and +15 °C
for frost protection purposes. It is also possible to
adjust temperature hysteresis and set upper and lower
temperature alarms.
COOLING
Operation mode COOLING is used in homes, oces,
storerooms and such like. In this operation mode, the
thermostat works as a room thermostat for regulating
air conditioning or other cooling within a temperature
range of +5 °C to +45 °C. Energy saving programs are
primarily adapted for home and oce environments but
can also be used for cooling, for example, storerooms.
MAX/MIN
The Max/Min operating position is mainly used to keep
roof and ground surfaces free of snow and ice. The
temperature range is adjustable between -20 °C and
+10 °C. For the best results and the best energy saving,
combined temperature and humidity control should
be used in the Max-/Min position, with associated Roof
Sensor or Ground Sensor.
Introduction
HEATING
Operation mode HEATING is used in homes, oces,
storerooms and such like. With this operation mode, you
can regulate the heating within a temperature range of
+5 °C to +45 °C. The thermostat can be used as a oor
thermostat, room thermostat or room thermostat with
over heating protection for wood oors. The energy
saving program is primarily adapted for home and
oce environments, but can also be used for regulating
heating levels in, for example, storerooms.
Four operation modes
The manual, like the thermostat, is divided into four operation modes so
that you only need to read about the functions you will use. The thermostat
operation mode can only be installed in the start menu, which is shown the
rst time the thermostat is started (read more about the start menu on page 8)
or after it has been reset.

Menu navigation
The functions in the thermostat are arranged in a system of menus and submenus.
The Main menu always contains three submenus TEMP, PROGRAM and SYSTEM.
There are further choices under these.
The rst time the thermostat is started, a number of requisite values must be set
in the START menu (see page 8). The START menu is then not shown again: the
thermostat always opens in display mode (see page 9).
The thermostat has two modes for background lighting, full and half strength.
If no buttons are pressed for 30 seconds, the background lighting reverts to half
strength. By pressing one of the three buttons, you can change to full strength;
the thermostat remains in display mode.
The menus are reached by pressing a second time in display mode.
The top row is always the name of the menu you are in. Use or to move the
round marker; the marked line you are on blinks. Press to select the marked
alternative. At the bottom of each menu there is an EXIT, which returns you to the
previous menu.
To reset the thermostat to factory settings, use the RESET function, which you can

Operation mode Heating
Heating mode is used in homes, oces, storerooms and such like.
With this operation mode, you can regulate the heating within a
temperature range of +5 °C to +45 °C. The thermostat can be used as a
oor thermostat, room thermostat or room thermostat with over heating
protection for wood oors. The energy saving program is primarily
adapted for home and oce environments, but can also be used for
regulating heating levels in, for example, storerooms.
Main menu MAIN MENU
MAIN MENU contains three submenus: TEMP, PROGRAM, SYSTEM and EXIT, which re-
turns you to display mode.
Temperature menu TEMP
The temperature menu contains the functions that in some way concern direct
temperature regulation. This is where the set point and, if applicable, over heating
protection are set. The temperature menu is reached via TEMP in the MAIN MENU.
Set point TEMP
The set point setting is under TEMP in the temperature menu. Set the required
temperature by pressing or and conrm by pressing . The set point can
be set to an accuracy of 0.5 degrees within the range +5 °C to +45 °C; it is preset
to+22 °C.
Over heating protection OH PROTECTION
Over heating protection works as a oor temperature limiter; if you have a wood
or laminate oor, you must always use a room sensor with over heating protection
to ensure that the oor material is safeguarded against over heating and damage.
Over heating protection is under OH PROTECTION under TEMP. The limitation can be
set between +5 °C and +45 °C. The factory setting is +35 °C, which gives a surface
temperature of about +27 °C.

The surface temperature is an average value and varies somewhat depending
on the material and the thickness. Denser (harder) wood insulates less than
softer wood, which increases the surface temperature. Also, the thinner the oor,
thehigher the surface temperature.
Two sensors are required for over heating protection: a room sensor (sensor A)
and an over heating protection sensor (sensor B).
Program menu PROGRAM
A smart way of saving energy is to adapt the heating to suit the needs through-
out the day and, for example, lower the temperature when there is nobody
home. There are four dierent ways of lowering the temperature: two preset pro-
grams for home or oce environments, one program for personal settings and
a frost protection program. There is no need to consider the heating time when
programming since the thermostat has an adaptive function that applies this
automatically.
The programs are in the MAIN MENU under PROGRAM. To change program, browse
using or and select using . The manual program is the factory setting, i.e.
you set the required temperature (set point) and the thermostat maintains that
temperature.
Program for home environment HOME
The temperature is lowered automatically by 5 °C at the following times:
Monday–Friday 08:30–15:00 and every day between 23:00–05:00.
The home environment program is under PROGRAM in the MAIN MENU. Select HOME
using and a message is shown for two seconds to conrm that the program
has been activated. You can then see in display mode that the program is active
when HOME is shown on the second row.
The temperature can be set between +5 °C and +45 °C. The thermostat works
from the temperature that is set in the manual program where the factory setting
is +22 °C. If you change the temperature in the manual program, or the set point
in the TEMP menu, the thermostat works from the new temperature, and lowers
the temperature by +5 °C from the newly set temperature.
Program for oce environment OFFICE
The temperature is lowered automatically by 5 °C apart from at the following times:
Monday–Friday 06:00–18:00.
The oce environment program is under PROGRAM in the MAIN MENU. Select OFFICE
using and a message is shown for two seconds to conrm that the program
has been activated. You can then see in display mode that the program is active
when OFFICE is shown on the second row.

13
The temperature can be set between +5 °C and +45 °C. The thermostat works
from the temperature that is set in the manual program where the factory setting
is +22 °C. If you change the temperature in the manual program, or the set point
in the TEMP menu, the thermostat works from the new temperature, and lowers
the temperature by +5 °C from the newly set temperature.
Holiday program HOLIDAY
This program is intended for saving energy and safeguarding against frost
damage in premises that are empty or unused for long periods, such as holiday
homes and storerooms, or unusually long periods of absence from home. The
holiday program can be controlled via a remote control unit. There are three
menu alternatives to choose between under HOLIDAY: ACTIVATE, CHANGE and RESET.
HOLIDAY is under PROGRAM in the MAIN MENU. The temperature can be set between
+5 °C and +20 °C; the factory setting is +12 °C.
ACTIVATE
The program is started with ACTIVATE, and from there you can choose to use TIMER
SETTING. If you want to start the program without the timer function, select NO and
the program will then be active until another program is started. If you select YES,
the program will remain active for the selected time and will then return to the
previously used program.
The rst time the program is used, the time and temperature must be set under
CHANGE. All the settings are saved in the memory and are not lost even if a
power cut occurs, but, in this case, the clock must be reset to obtain normal
functionality again.
CHANGE
To make changes to the settings, select CHANGE; TEMP is used to set the temperature
you want the thermostat to maintain when the program is activated, TIMER is used
to reset the current start and stop times; REMOTE is used to activate remote control
if applicable.
RESET
There is also a reset function, which resets the program to the factory setting, +12
°C, and deletes all the time settings.
REMOTE CONTROL
The holiday program can be controlled via a remote control unit. The unit is
connected to the applicable terminal block; see the wiring diagram. The holiday
program is activated when the remote control input is closed, and is deactivated
when it is opened again. The thermostat then returns to its previous setting.

14
Personal program [PERSONAL]
Manual setting of the program allows optimisation of energy consumption to suit
just your needs by making settings for four events each day: WAKE, AWAY, HOME
and NIGHT. There are three menu alternatives to choose between: ACTIVATE, CHANGE
and RESET.
The personal program PERSONAL is under PROGRAM in the MAIN MENU. The tempera-
ture can be set between +5 °C and +45 °C; the factory setting is +22 °C.
ACTIVATE
The program is started with ACTIVATE and remains active until another program is
started. All the settings are saved in the memory and are not lost even if a power
cut occurs for a period longer than two days, but, in this case, the clock must be
reset to obtain normal functionality again.
CHANGE
To set your personal program go in under CHANGE. There are dierent ways of
setting the various events; you can choose to program day by day, weekend
(Saturday and Sunday) or the whole week. It is normally easiest to set the whole
week rst and then adjust this for the days requiring a dierent setting.
When you have decided on the day(s) the event shall be set for, set the time of day
they shall occur at and the required oor temperature at that time.
Start by setting the time, which is blinking. Browse with the or the button to
the time you want the event WAKE to occur. First set hours, conrm with , then
minutes, conrm with . Browse to the required temperature for WAKE. Conrm
with and AWAY then shows. Repeat the steps above to set the time and tempera-
ture, and HOME then shows. Repeat the steps above to set the time and temperature,
and NIGHT then shows. Repeat the steps above to set the time and temperature.
RESET
Thereisalso aresetfunction,which resetsthe programtothefactorysetting,+22 °C,
and deletes all the time settings.
Program for hotel environments HOTEL
This program allows you to control the heating via external card readers with
a delay time, since the thermostat has an integrated time relay function. The
temperature settings change automatically when the hotel guest comes into or
leaves the room and the delay time is fully adjustable, making it easy to decide
how long the heating is to keep running after the guest has left the room.
The Hotel program can be found under PROGRAMS in the MAIN MENU. You select
HOTEL with . This displays the dierent settings that you can make in the pro-
gram. There are three settings to choose from: +HEAT, LOW TEMP and ACTIVATE.

15
+HEAT
Time relay, O-delay: adjustable from 0 to 4 hours. The factory setting is 2 hours.
LOW TEMP
Set point can be set to between +5 °C and +20 °C. The factory setting is +15 °C.
ACTIVATE
You start the program with ACTIVATE and the program will remain active until you
choose to start another program. All settings are saved in the memory and they
will not be lost even if the power is cut for longer than 48 hours, but you will
need to reset the clock for everything to function normally again. For two sec-
onds, you see a message conrming that the program has been activated. You
can then see that the program is active because HOTEL is shown on the second
line in display mode.
HIGH TEMP
The temperature can be set to between +5 °C and +45 °C. The thermostat reacts
based on the temperature that is set in the manual program, where the factory
setting is +25 °C. If the temperature is changed in the manual program, or the
set point is changed in the TEMP menu, the thermostat will react based on the
new temperature.
REMOTE CONTROL
The Hotel program is controlled by a remote control device, such as a card reader,
connected to the designated terminal blocks. The thermostat switches from low
to high temperature when the device’s input circuit closes. When the input circuit
opens, the thermostat returns to the “low” set point after the set time.
System setting menu SYSTEM
Under system settings, you will nd settings for, for example, language and date,
as well as resetting functions for the time counter and for complete resetting to
factory settings. The system settings are under SYSTEM in the MAIN MENU.
Language LANGUAGE
You can choose between several languages; the factory setting is English.
Set the required language by scrolling through them using the or button
and conrm with .
You can also use the shortcuts in the display mode (press for three seconds).
Then you go directly to the language menu. A practical function if you, by
mistake, set the wrong language and then have dicultly nding the language
menu again.

16
Date and time DATE/TIME
A set time and date can be changed if needed, for example, if the electrical supply
to the thermostat was disrupted for a period of more than fty hours. The setting
function then comes up automatically.
You will nd date and time setting in the MAIN MENU under SYSTEM and DATE/TIME.
Change the value that blinks with either or and conrm with .
Summer and winter time S/W TIME
The thermostat calendar and clock are automatically set to summer and winter
time but the function can, if it is not required, be switched o.
Summer and winter settings are in the MAIN MENU under SYSTEM; select S/W TIME.
Switch o the function under ON/OFF in the menu and select OFF, a message is
shown for a short time conrming that the function is switched o. Activate the
function in the opposite way by selecting ON.
Sensor settings SENSOR
The thermostat can regulate temperature in three ways to accommodate both
comfort temperature and possible temperature requirement for oor material.
The sensor settings are in the SYSTEM menu under SENSOR, and there select the
sensor you want to use by browsing with or and conrm with .
Adaptive function ADAPTIVE
The thermostat has a function that calculates when heating should be started to
provide the required temperature at the right time. The function is activated on
delivery, but can be switched o as required.
You will nd the settings for adaptive function in the MAIN MENU under SYSTEM,
and there you select ADAPTIVE. Switch o the function under ON/OFF in the menu
and select OFF, a message is shown for a short time conrming that the function is
switched o. Activate the function in the opposite way by selecting ON.
Ventilation mode VENT
If the room temperature sinks by more than 3 °C in a minute, for example, when
airing, ventilation mode is activated. The thermostat then deactivates heating for
15 minutes, after which it returns to the same setting; ventilation mode shows in
the display when it is activated. The function is activated on delivery, but can be
switched o as required.
You will nd the settings for adaptive function in the MAIN MENU under SYSTEM,
and there you select ADAPTIVE. Switch o the function under ON/OFF in the menu
and select OFF, a message is shown for a short time conrming that the function is
switched o. Activate the function in the opposite way by selecting ON.
FLOOR THERMOSTAT
The most common installation that suits most rooms and needs. A sensor placed
in the oor measures the temperature and regulates the heating.
Note that the sensor measures the temperature below the surface; if the

17
thermostat is set as a oor thermostat, this is the temperature that you set in the
TEMP menu and not the temperature in the room or on the surface of the oor.
ROOM THERMOSTAT
If the room is very large or has large areas of glass, it can sometimes be better to
regulate the heating via a room sensor. A complementary sensor (E 85 816 22) is
then required.When the thermostat is set as a room thermostat, it is the room
temperature that is set in the TEMP menu.
ROOM THERMOSTAT WITH OVER HEATING PROTECTION
If you have a wood or laminate oor, you must use this installation to safeguard
the oor material against over heating and damage. The preset temperature
limitation setting is +35 °C. Read more about over heating protection in the
section Temperature menu. A complementary sensor (E 85 81622) is then required.
Reset RESET
There are three choices under the reset menu: CONN TIME, OP MODE and FAC SET.
Youwill nd the RESET menu under SYSTEM in the MAIN MENU.
Reset connection time CONN TIME
The connection time is shown in hours; as with a vehicle trip meter, it shows the
number of hours an installation has been connected for since it was last reset. This
is benecial if you want to calculate the energy consumption for a certain period.
The thermostat also has a counter that cannot be reset, which shows the total
hours the installation has been connected for.
To see the total and momentary connection times, press when the thermostat is

Program menu PROGRAM
A smart way of saving energy is to adapt the air conditioning to the needs through-
out the day and, for example, lower the temperature when there is nobody there.
There are four dierent ways of raising the temperature: two preset programs for
home or oce environments, one program for personal settings and a holiday
program.
There is no need to consider the cooling time when programming since the
thermostat has an adaptive function that applies this automatically.
Operation mode Cooling
Operation mode Cooling is used in home, oce, storeroom environments and
such like. In this operation mode, the thermostat works as a room thermostat
for regulating air conditioning or other cooling within a temperature range of
+5 °C to +45 °C. Energy saving programs are primarily adapted for home and
oce environments but can also be used for cooling, for example, storerooms.
Main menu MAIN MENU
MAIN MENU contains three submenus: TEMPERATURE, PROGRAM, SYSTEM and EXIT,
which returns you to display mode.

Holiday program HOLIDAY
This program is intended for protection against over heating of, for example,
electronic equipment in premises that are empty or unused for long periods,
such as holiday homes and storerooms, or longer periods of absence from the
normally used accommodation. The holiday program can be controlled via a
remote control unit. There are three menu alternatives to choose between under
HOLIDAY: ACTIVATE, CHANGE and RESET.
HOLIDAY is under PROGRAM in the MAIN MENU. The temperature can be set between
+20 °C and +40 °C; the factory setting is +27 °C.

the program will then be active until another program is started. If you select YES,
the program will remain active for the selected time and will then return to the
previously used program.
The rst time the program is used, the time and temperature must be set
under CHANGE. All the settings are saved in the memory and are not lost even
if a power cut occurs, but, in this case, the clock must be reset to obtain normal
functionalityagain.
CHANGE
To make changes to the settings, select CHANGE; TEMP is used to set the tempera-
ture you want the thermostat to maintain when the program is activated, TIMER is
