TEMPERATURE CONTROLLER TOUCH LINE Model RSD
Description
RSD is a temperature controller for refrigerator rooms using touch technology for the keyboard. Through a PTC sensor controls temperatures in range -50÷+150 °C (-58÷+302 °F).
In scale -19.9÷+99.9°C there is a decimal analysis with accuracy ±0.1°C. It has three relays (compressor, fan and level control), deFrost control and buzzer activation due to an
alarm.
Start up
At the startup of the device, the temperature controller performs a self-ckeck for 7 sec and the room temperature is displayed. Do not touch the screen during self-check. By pressing
the two arrows (
[
],[
] ) at the same time for 3 seconds the countdown starts and
the temperature controller unlocks
(images below)
. By pressing
[
] for 3sec we turn ON or
turn OFF the controller (images below)
. The keyboard locks automatically after 50sec without activity.

Managing the parameters
By pressing [
] we enter the parameter’s menu.
The first parameter SPo is displayed and with the
[
], [
]
we scroll into the parameters with the order they
appear to the parameters table below.
By pressing [
] the value of the parameter is displayed and with the
[
], [
]
we change the value.
By pressing [
] we confirm the new value and the name of the parameter is displayed.
By pressing [
] we cancel the new value and the name of the parameter is displayed.
By pressing [
] we exit the parameters menu.
Connections
Serial input
RSD can connect to the key programmer or the data logger Mini Logger or the CAMIN network or to an external device for exporting alarms. From the parameters UF
and Add we can adjust the serial input.
Key programmer: controller’s parameter values can be saved or retrieved from the programming key. Connect the programming key to the controller and by pressing
[
] and
[
]
the device connects with the key and the message Eo is displayed.
By pressing
[
]
the device reads the parameters from the key and the message ro = read O.K. or rF = read Fail is displayed.
By pressing
[
]
the device writes the parameters to the key and the message Yo = Write O.K. or YF = Write Fail is displayed.
In case of failure (rF or YF) reenter the key to the serial input and repeat the procedure from the beginning. The key can connect to all
devices. If you try to
read the parameters of a different device, message rF is displayed. At any time we can perform the aforesaid operation. After 10 sec the key is disconnected.
Data logger Mini Logger: the controller can connect to the data logger and save its temperatures based on selected minutes, its status and alarms to a microSD
memory card. It connects to the controller via a cable and the parameter Add = 1 must be adjusted.
CAMIN PC network: the controller can connect to CAMIN network (RS485, modbus protocol) through an interface NET-IN-1. CAMIN is an application designed to
collect information, watch and fully control a net of devices. The maximum length of the net can be 1000 meters
.
