MANUAL “Clima” CAREL for the modulation of burner
Clock digital proportional temperature regulator. Timer and real-time clock for day and night operation.
Delivered with the warm air heater series X and variation, or with roof top AMC..XR..fitted with
modulating burner RX
General features
“CLIMA” Carel mod.
ADCA000110
, is an electronic instrument
,
installed in the heated room, as the remote user terminal
,
with following operating
functions:
1) Regulates the modulation of the RX burner. The modulation starts when
“CLIMA”
detects a room temperature of Set-Point T minus 2°C
(configured by the manufacturer with parameter dFA).
“CLIMA”
operates a proportional regulation (modulation) of the RX burner, with 0-10V
analogue output. Example:
“CLIMA”
room temperature Set-Point 20°C;
“CLIMA”
starts modulate the burner when detect 18°C and modulates between 18-20°C.
The modulation can be operated even by a NTC sensor on air outlet temperature (example SET POINT 44°C of air outlet temperature. The
modulation starts at 42°C of air outlet temperature); or by NTC sensor on air recirculation temperature (example SET POINT 20°C of air
recirculation temperature; modulation starts at 18°C). In this case there is a need of a room thermostat to switch ON-OFF the burner. This
solution is applied also with roof top operated by PCB controller.
2) Operates as room thermostate: switch-off the burner when detects room temperature of Set-Point T (11) set on the
“CLIMA”.
The burner
start-on again when room temperature is –0,5°C (configured by the manufacturer with parameter
dlF
) of Set-Point T (11). The burner start-
on at a modulate thermal power, set by the manufacturer with parameter
dSA
. Example:
“CLIMA”
room temperature Set-Point 20°C;
“CLIMA”
switch-off the burner when detects 20°C; when detects 19,5°C in the room
“CLIMA”
starts-on again the burner.
This function is not
operating with roof top, because operated by PCB controller.
3) Setting the clock, the time bands, and the default value of the timer for the burner RX and so for the warm air heater X, in “heating”. For this
setting press
PRG
and, by pressing in sequence
SET,
, SET
set the following parameters
: rtC
: real time;
dAy
: starting time of day mode;
nlt
: starting time of night mode;
SLP
eventually: time interval between
dAy
day running mode
,
and
nlt
night running mode. With the clock
incorporate is possible set the time bands modes, 2 bands per day, the same for all the 7 days of the week. In case of electric feeding’s lack,
rtC
real time remains in memory for 2 days maximum.
The supervisor remote control option (purchasing the accessory code IROPZ48500) allows the data from the instrument to be monitored and
saved.
The function, of Set-Point compensation based on the outdoor temperature probe reading NTC is available. For this “CLIMA” must be connect to the
NTC outdoor temperature probe reading (option on demand).
Installation
“CLIMA”
regulator is delivered, together with the warm air heater and burner,with parameters
dFA , dSA, dlF
already configured by the
manufacturer (see par. 1
and 2
). The installer must set the
rtC
real time parameter; and
dAy
: starting time of day mode;
nlt
: starting time of
night mode;
SLP
eventually: time interval between
dAy
day running mode
,
and
nlt
night running mode.
Disconnect the power supply to the controller and the loads before working on the instrument.
For correct installation, proceed as follows:
• separate the front panel from the rear part by levering the tab, as shown in Figure 2.
• Fasten the instrument to the wall horizontally, so as to allow the circulation of air. For accurate measurements, position the instrument away from
sources of heat or humidity, away from windows or outside walls.
• Pass the connection cables though the centre hole in the bottom shell and connect them to the terminal block provided, observing the markings
shown on the label. Separate the connection and control cables from the relay cables.
Place a clamp around the two groups of cables (signal and power supply, relay outputs) near the terminals
.
• Check inside the
“CLIMA”
the dipswitches must be in the following position (see the table below ).
