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 In-depth description for LK ICS-RF8.

The system benefits from:

EN.33.C.891008

Summary of Contents for LK ICS-RF8

Page 1 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.
Page 2: Installation Instructions
Install the receiver adjacent to the Manifold. Ensure there is enough space below the unit to remove the lid and that it is possible to connect LK ICS MEM Stick vertically downwards. If the receiver is mounted in a steel cabinet it is recommended that the radio link is placed outside the cabinet. This is easily done with LK Antenna Cable ICS (accessories).
Page 3 LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 Quick Guide – programming the thermostats Check that the radio link cable is connected to the receiver's RF input Press the L key on the receiver unit for at least 3 seconds, the L-LED will light green.
Page 4: Holiday Function
When on vacation, the temperature of the heating system can be lowered for the duration; this is easily done from any thermostat in the system by activating the built-in holiday mode. LK ICS then keeps track of how many days the system should have a lower temperature and makes sure that the house is again warmed on return from vacation.
Page 5: Function Description
LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 Function description The LK Receiver unit ICS RF8 has eight channels, allowing up to eight LK Thermostat ICS-RF to be connected to the unit. The receiver collects data from each room thermostat and sends control signals to LK actuators. One thermostat can control more than one channel.
Page 6 ICS thermostats can be easily set for more than one channel/actuator output. Please see the Quick Guide. LK Actuators are opened once every 24 hrs. to prevent the manifold valves from sticking in the closed position (essential long term maintenance).
Page 7 LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 Pump relay (illus. 9) Circulation pumps (i.e. the pump in a shunt pack) can be controlled through the unit’s pump relay. The relay is located under the lid of "high voltage side" of the receiver unit.
Page 8 LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 NOTE: the relay contact is "potential free" (volt free), which means that the boiler relay contacts must be powered from an external source and NOT from the receiver unit. The boiler/heat source will fire approximately 6 minutes after any one channel calls for heat.
Page 9 The receiver is equipped with a MEM port that is used primarily when there is to be a system log maintained. Measurement data is sent to LK ICS MEM Stick once per minute. With the help of measurement data and LK ICS Analyzer software, the installer can easily verify/analyze the installation.
Page 10 The thermostat, as standard, monitors internal room temperature. It is also possible to equip the thermostat with LK External Sensor ICS. Additionally the thermostat can control/check the floor temperature alone, or the floor temperature in combination with the room temperature. NOTE: for further information, please see the section entitled External sensors.
Page 11 NOTE: for further information, please see the section entitled: Weekly Programming. LK ICS has a so called "holiday function" which can be activated from any thermostat in the system. The holiday function enables lower the temperatures for extended periods, such as during a vacation. When activated, the feature lowers the temperature of all thermostats to 12 degrees.

Page 13 If necessary, the signal can be improved by placing the thermostat closer to the receiver unit, if possible. Alternatively, the radio link can be moved by using the LK Antenna Cable. If the problem persists, the signal is strengthened by use of LK Repeater.
Page 14 LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 NOTE: The system clock must be set accurately for this feature to work properly. Weekly program - temperatures The units are supplied with the following default temperature values:...

Page 16 LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 Increase/decrease the temperature by using the +/- key Press Mode once when the temperature is flashing. Symbol for constantly disconnected weekly programs appear on the display, see illus. 5 in the display above.
Page 17 LK Floor Heating | Assembly Instructions | LK Room Temperature Control ICS-RF8 NOTE: Observe that the "countdown" starts from the moment the "activation" occurs which means that the next day at the same time of the initial activation a day has disappeared.

End the sequence by pressing the L key on the receiver unit, following which the L-LED goes out. Battery replacement LK Room Thermostat RF ICS comes with three 1.5 volt LR03 batteries (AAA). The batteries have a life expectancy of two years. Life expectancy is affected by the user's choices, such as activated background lighting.
