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
10 and 11.
Sensor C (moisture) is
connected to 12 and 13.
A possible remote control
unit is connected to 9 and 14.

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
read more about on page 16.

Operation mode OPERATION MODE
There a four operation modes: HEATING, COOLING,INDUSTRY or MAX/MIN. The
operation mode can only be selected in the start menu and cannot be
changed after this menu is left.
The settings for heating and cooling are for regulating the temperature in
home, oce and storeroom environments or similar. The industry mode is
used for controlling industrial processes and high temperatures or to safe-
guard sensitive installations against frost damage. Max/Min is used above
all to keep roof and ground surfaces free of snow and ice.
Set the required operation mode by scrolling through them using the
or button and conrm with . When you have selected the mode that
