LK Room Temperature Control ICS-RF8

Design

LK Room Temperature Control ICS-RF8 is a wireless control system designed for LK Floor Heating. LK ICS-
RF8 consists of LK Room Thermostats ICS-RF, an LK Receiver unit ICS RF8 and LK Actuators.

Function

Room thermostats regulate the temperature of each room (zone) via wireless signal transmission to the receiving
control unit. The actuators for each room/zone are controlled by the receiver unit.
The system has several "smart features" such as adaptive weekly programming, holiday functions, the ability
to connect external sensors, external temperature set back via GSM switches, and more. For further information,
please see the
