1. DESCRIPTION:
Electronic control device designed to control the temperature from 2 to 6 independent zones in centralised duct
type air conditioning installations. The room wireless thermostats are connected by Rs485 communication bus, with a central control
panel which manages the motorised dampers installed in each zone and the ON/OFF of the ducted electronic Air Handling Unit.
2. SYSTEM WIRING:
All of the system components are wired to the control centre. It
is recommended that you locate it close to the inner unit of the air conditioning
equipment. Place that control panel only accessible to authorized the general public.
Fix it into the wall using screws or use the rear DIN rail fixation.
2.1. Power:
Supply the centre with 230 VAC on the
Power Supply
terminals, wires Smin=1 mm
2
, Smax=1.5 mm
2
.
2.2. Thermostats:
Connect it the
A B Rs485
output of the control panel.. Use a parallel wire Smin=0.5 mm
2
, Smax=0.75 mm
2
.
Respect the polarity of the bus
(A=White, B=Blue)
. In the case of cable lenghs (L>250 m) close the circuit with a 120
resistance.
See attached scheme.
2.3. Motorised dampers:
Connect the motors for each regulation to terminal blocks 1 to 6 on the board. Use a wire (red (+) / black (-))
Smin=0.75 mm
2
, Smax=1.0 mm
2
. In the event of two regulations per zone (maximum recommended), connect the parallel as indicated
in Zone 5 of the figure. The MASTER zone should be connected to output 1.
2.4. Air conditioning equipment:
The control panel can be connected or not at the production equipment depending on the type of
installation:
2.4.1.
KCA-SUB (Sub-zone installation):
The system is not connected at the production equipment because they remain some
zones without regulation. The changeover (heating/cooling) is automatically made by the sound temperature which is installed in
the supply duct.
NEVER install a regulation damper and a zone thermostat in the room where is installed the machine
thermostat, in that case the system will not function properly.
2.4.2.
KCA (Zoning installation):
The control panel is connected to the AHU following the wiring diagram supplied by MADEL (ask
with the brand and model of the equipment used). The machine thermostat cannot be replaced and must always be connected to
prevent the air conditioning equipment from stopping. Thus, select the max. order temperature in summer and the min. order
temperature in winter. Heating/Cooling changeover must be made on the machine thermostat and on the master thermostat
