LK Actuator 24V AC  

Connect the actuators, bearing in mind the following:
A control zone consists of 1 LK Room Thermostat (trans-
mitter) but can contain one or more under 

ß

 oor heating 

loops equipped with actuators. All actuators in a control 
zone must be connected to a common channel on the 
receiver unit.

LK Actuator.

Cq 4 and Cq 6 Control Unit 

For the Cq 4 and Cq 6 Receiver Unit, a maximum of 4
actuators can be connected to each channel. The circuit
diagram shows that all channels in Cq 4, and 2 channels in
Cq 6, have double terminal boards, a or c respectively, for
connecting the actuators. Cq4 and Cq6 receiver units can
operate a maximum of 16 actuators.

When connecting two or more actuators to the same 
channel, the connections must be only to the double circuit
boards.

DESIGN

The LK Room Thermostat Cq (transmitter) regulates the 
temperature in a zone (e.g. a room) via radio signals to 
the receiver unit. Note: locate the receiver unit close to 
the heating circuit manifold.

The receiver unit converts radio signals to control signals
to activate the actuators.

The receiver unit is available in three sizes: 

•  LK Cq 1 intended for 1 control zone. 
•  LK Cq 4 for a maximum of 4 control zones, (channel 1 - 4).
 • LK Cq 6 for a maximum of 6 control zones, (channel 1 - 6).

The receiver unit functions along the same principles, but
the Cq 1 unit, which only has one receiver channel, differs
somewhat in its design. The instructions for this model 
therefore contain a few additions.

REQUIREMENTS

A suitably quali

Þ

 ed electrician or installation engineer, must

carry out electrical installation in accordance with the 
circuit diagram 

Þ

 gs. 1 + 2. To achieve protection class 2,

all necessary installation measures must be taken.

Installation and start-up (memorizing) is best carried out
in the following order:

The receiver unit  

The receiver unit should be located close to heating circuit
manifold to avoid lengthening the actuator connection 
cables.

In certain circumstances, the transmitters (thermostat)
signal may be too weak, e.g. if the receiver unit is assembled
in a metal enclosure (e.g. LK Manifold Cabinet). In these
cases, the LK Antenna Cq. Should is used. (See separate
section, LK Antenna Cq.)
