Assembly instructions | LK Room Temperature Control ICS.2
Function
The room thermostat controls the temperature
in each room (zone) via wireless or wired signal
transmission to the receiver. The actuators for
each room/zone are operated via the receiver.
Self-modulation technique
In order for your underfloor heating to be con-
trolled as energy efficiently as possible, LK ICS.2
works with a self-modulation technique. The
self-modulation technique means that the flow
in the floor heating circuits is continuously opti-
mised based on the needs of the room and there-
by provides better comfort and a more energy
efficient and environmentally smarter heating
system compared to systems with traditional
ON/OFF technology.
The features the system offers include the
following:
•
Self-modulation technique
•
Internet via the LK Webserver ICS.2
accessory
•
Room thermostat in high gloss white, high
gloss black or silver grey
•
Adaptive week program
•
Holiday function
•
Logging/analysis function*
•
Wired or wireless communication between
thermostat and receiver*
•
Valve exercising function
•
Pump logics*
•
Control of heat source*
•
Fire place function
•
By-pass function
•
Temperature range limits
* Applies to LK Receiver 8 ICS.2
Design
LK Room Temperature Control ICS.2 is a control
system designed for LK Floor Heating. The sys-
tem is suitable for small, medium or large build-
ing installations. LK ICS.2 has been designed to
provide high levels of comfort and energy ef-
ficient heating systems thanks to its advanced
self-modulation technique.
The system consists of LK Receiver ICS.2,
LK Room Thermostat ICS.2 and LK Actuators
24 V. Communications between the room ther-
mostat and the receiver can either be wireless or
wired.
The receiver is available in versions for 1-chan-
nel and 8-channel. The receiver with 1 channel
can communicate with 1 room thermostat.
The receiver with 8 channels can communicate
with 1 to 8 room thermostats. The receiver with
8 channels can combine both wireless and wired
communications.
If the system consists of more than one receiver,
the units can communicate wirelessly with each
other in order for common functions to work.
This includes controlling the circulation pump,
heat source, the ability to connect LK Webserver
to the Internet.
LK ICS.2 includes a variety of smart features
such as adaptive week programming, holiday
functions, fire place function, the capability of
connecting to an external sensor. By using the LK
Webserver ICS.2 accessory, you can control your
heating system via the Internet from a mobile
phone, tablet or computer. LK ICS.2 can commu-
nicate using the Modbus protocol RS485/RTU for
connection to the general building automatics.
