Assembly instructions ICS.2
Requirements
The requirements for the proper functioning of
the underfloor heating system is a weather-de-
pendent control system for the supply temper-
ature and a well implemented and documented
adjustment to the primary and loop flows.
Assembly of room thermostat and receiver
1. Install the receiver in direct connection to
the heating circuit manifold.
2. Install all room thermostat back plates on
the inner wall about 1.5 m above the floor.
Note which way is up or down, see arrow
in the back plate. Avoid locations that may
affect the room thermostat function (e.g.
solar radiation and ventilation).
3. For wired room thermostats, connect cable
2 x 0.5 mm to the terminal in the back plate
2
marked ICS BOX.
Fit the thermostat cable to the green termi-
nal that is enclosed with the wired room
thermostat. Press the room thermostat's
green terminal block into the receiver's up-
per terminal strip marked with thermostat
symbols.
4. Snap the room thermostat into its back plate.
5. Fit the actuator wire to the terminal block.
Press the actuator terminal blocks into the
receiver's lower terminal strip marked with
the valve/actuator symbol.
NOTE: Maximum of two LK Actuators per
terminal and a maximum of twelve LK Ac-
tuators per receiver 8 and five LK Actuators
per receiver 1.
6. Run the actuator cables in the strain relief
grooves.

Install the room thermostat's back plate about 1.5 m above
the floor. Note the arrow on the back plate indicating
which way is up. For the wired room thermostat, the cable
is connected from the receiver to the terminal marked ICS
BOX. Where necessary, the external sensor is connected to
the EXT Sensor terminal.

Remember to connect the wired room thermostats, if in-
stalled, to the upper terminal strip and the actuators to the
lower terminal strip.
Learning for room thermostats and receivers
When learning a system, the constituent receivers
must be defined as the Master unit or Slave unit
depending only on the size of the system.
In a system with only one receiver, this is to be
programmed as a Master unit.
In a system with multiple receivers, one receiver
shall be programmed as Master Unit and the oth-
ers as Slave units. The units then create a wireless
network. The wireless network enables common
functions such as holiday function, pump con-
trol and the capability for web control via the LK
Webserver ICS.2 accessory, etc.
A network-connected system may consist of a maxi-
mum of one Master unit and seven Slave units.
