LK Wireless Room Control Cq (NC).
LK Actuator 24V AC
Connect the actuators, bearing in mind the fol-
lowing:
A control zone consists of 1 LK Room Thermostat
(transmitter) but can contain one or more under
floor heating loops equipped with actuators. All
actuators in a control zone must be connected to
a common channel on the receiver unit.
To aid assembly to the manifold, the actuators are
supplied “open”. Once an actuator is powered
(for a minimum of 6 minutes) an internal pin is
released and the actuator will now operate.
LK Actuator.
Design
The LK Room Thermostat Cq (transmitter) regula-
tes the temperature in a zone (e.g. a room) via ra-
dio 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 prin-
ciples, but the Cq 1 unit, which only has one re-
ceiver channel, differs somewhat in its design.
The instructions for this model therefore contain
a few additions.
Requirements
A suitably qualified electrician or installation
engineer, must carry out electrical installation in
accordance with the circuit diagram figs. 1 + 2. To
achieve protection class 2, all necessary installa-
tion measures must be taken.
Installation and start-up (memorizing) is best car-
ried out in the following order:
The receiver unit
The receiver unit should be located close to hea-
ting circuit manifold to avoid lengthening the ac-
tuator connection cables.
In certain circumstances, the transmitters (ther-
mostat) signal may be too weak, e.g. if the recei-
ver unit is assembled in a metal enclosure (e.g.
LK Manifold Cabinet). In these cases, the LK Re-
peater Cq should be used. See separate section,
LK Repeater Cq.
