LK Receiver 1 ICS.2
The LK Receiver 1 ICS.2 has 1 channel which means
only 1 LK Room Thermostat ICS.2 can be assigned/
connected to the unit.
The Receiver collects data from the room thermostat
and sends control signals to the LK Actuators. As the
communication between the receiver and actuators
is via a cable, the receiver should be placed directly
adjacent to the underfloor heating manifold.
