LK Room Thermostat ICS.2
Functional description
LK Room Thermostat ICS.2 is available as a ver-
sion where the communication between the room
thermostat and the receiver is wireless as well as
in a wired version where the communication be-
tween the room thermostat and the receiver takes
place via a two wire cable. In order to distinguish
between the room thermostats, the wireless room
thermostat is marked with RF and the wired ver-
sion with W.
It is possible to combine both wireless and wired
communications in LK Receiver 8 ICS.2.
The room thermostat is installed in the room/
zone it is to control. The room thermostat display
shows the current room temperature in the nor-
mal view. Set/required temperature is displayed
when you press the left arrow or right arrow once.
If you press again, this changes the temperature
in steps of 0.5 degrees.
The room thermostat is fitted with an internal
temperature sensor that senses the room temper-
ature. It is possible to fit the room thermostat with
a LK External Sensor ICS.2. The external sensor is
normally installed on the floor whereby the room
thermostat controls the floor temperature or the
floor temperature in combination with the room
temperature. See more under the heading Exter-
nal Sensors.
The room thermostat has a clock function that al-
lows you to lower the night temperature as part
of a week program. As standard, the programme
starts/stops when the programmed start/stop
times occur. You can also enable the thermostat's
adaptive control, which means that the system
is self-learning. Following an enabled adaptive
function, the thermostat calculates when the heat
needs to start in order to achieve the right temper-
ature at the required time. Temperature increases
are influenced by the adaptive function. Temper-
ature setback occurs after the programmed stop
time. Read more under the Week program head-
ing about how the function is activated.

The LK ICS.2 has a holiday function that can be ena-
bled from any thermostat in the system. The holiday
function involves you lowering the temperature for
a longer time in an easy way, such as during a holi-
day. When enabled, the function lowers the temper-
ature to 12 °C for all room thermostats. Read more
under the heading Holiday function.
If necessary, you can lock the room thermostat to
prevent unauthorised users from changing the
room thermostat settings. Read more under the
heading Button lock.
There is also a function that allows you to re-
strict the room thermostat setting temperature. In
apartment buildings, by way of example, where
it is desirable to limit the residents' room tem-
perature in a given range, such a minimum of
18 °C to max. 22 °C. Read more under the head-
ing Temperature range limits.
