3.6 Copy parameters from Master to Slave
(Upload)
All the parameters with upload attribute can be uploaded from a
Master controller to the Slave controllers in the subnetwork. The upload
attribute can only be set for the parameters using the VPM program
(Visual Parameter Manager). This procedure can be used instead of the
programming key, with the advantage of being able to update all the
Slave boards in the subnetwork at the same time, without powering down
the controllers and without overwriting the parameters that should not
be modifi ed, such as the serial address, the clock parameters, etc. rather
than having to repeat the procedure individually for each board with the
programming key.
Procedure:
1. press Prg/mute and Set together for more than 5 seconds (if there are
active alarms the buzzer is muted): the display shows the number 0
fl ashing;
2. press UP or DOWN and enter the PASSWORD: 66. Confi rm by
selecting Set;
3. press UP or DOWN to select the Slave controller to be programmed.
Confi rm by selecting Set. Selecting ALL programs all the Slave
controllers in the network;
4. during the programming procedure, the terminal display shows the
normal display alternating with the message uPL, and the spanner
icon comes on;
5. once the programming procedure is complete, the message uPL
disappears and the spanner icon goes off . In the event of errors, the
message uPX is displayed (X= number of the Slave controller where
the error occurred).
3.7 Maximum and minimum temperature
monitoring (parameters r5,rt,rH,rL)
The minimum and maximum temperatures measured by the probe set
for parameter r5 can be monitored over a period of up to 999 hours (more
than 41 days).
To enable this function, proceed as follows:
• enter advanced programming mode (type A parameters), as explained
in paragraph 3.3;
• set parameter r5 to select the probe used for monitoring (see the table
of parameters);
• display parameter rt and press Set to display the number of hours
minimum and maximum temperature monitoring has been active (if
just enabled, rt=0) or to restart temperature monitoring, press DOWN
for more than 5 seconds while displaying the hours (the message 'rES'
indicates the hours have been reset). The controller resets the hour
counter and restarts monitoring;
• to display the maximum temperature measured by the probe, read the
value associated with parameter rH;
• to display the minimum temperature measured by the probe, read the
value associated with parameter rL.

3.8 Using the remote control (accessory)
The MPXPRO remote control is an instrument developed to simplify
the programming and setup of an MPXPRO controller. As well as the
traditional remote keypad, it features a series of functions used to
override the status of the outputs and inputs, so as to completely test the
connections and the operation of the application.

Description
The MPXPRO remote control features a series of buttons, divided into
groups based on their function. In addition to the traditional remote
keypad, it has a special section for displaying the overall status of the
controller (probes, internal variables), manually overriding the inputs and
outputs, and manually positioning the electronic expansion valve (EEV).
The MPXPRO remote control interacts with all terminals/displays fi tted
with infrared receiver (IR00UGC300, IR00XGC300).
The parameter relating to the enabling code is H3:

Remote control during start-up
When started for the fi rst time, MPXPRO displays the start-up procedure.
In this phase, the remote control is always active on all controllers, without
distinction between codes, and consequently the parameters can be set
without having to activate the remote control or enter specifi c codes. As
a result, operate near the display is question, in order to avoid interfering
with other controllers.
Activating the remote control
Synch: enable the use of the remote control;Esc: disable the
Esc
use of the remote control.
After pressing Synch, each device displays its value of
parameter "H3: remote control enable code", if not null. The
Synch
numeric keypad can be used to specify the code of the
instrument in question, so as to avoid interference with the
other devices..
