3. MAIN FEATURES
SCBUS AND INFRANet, 2-WIRE BUS CONNECTION: A two-pole cable is required to connect the
master to the zone slave modules. This simplifies the connection.
The two-way communication runs along a RS-485 serial line made of a 2-wire twisted shielded cable (i.e.
Belden 8762 with PVC sheathing 2 twisted terminals + copper sheathing, 20 AWG, 89pF cables nominal
capacity, 161pF cable / copper sheathing nominal capacity). 1.000m max length tolerated for the network;
LCD DISPLAY: a large LCD display helps to keep the thermostat always under control at a glance. Scrolling
text messages and symbols describe the operations in progress. The display decimal range is: –50,0 and
999.0, out of this range the device switches automatically to integer numbers.
4. MODBus
MODBus communication enabled in write/read mode only if H0r= 0, in this case the icon
Through this parameter you enable/disable the MODBus connection, BMS, and the possibility to change the
parameters of the devices only by MODBus or by SCMQ10 keyboard. Especially if H0r is:.
0 = the MODbus is always enabled, change of the parameters of the devices are allowed only by MODBus,
you can not change them by SCMQ10, with the exclusion of the parameters Lrn, rSt or H0r;
NOTE: if H0r = 0 the value of the Modbus register n°141 tells to the SCMQ10 if the BMS is connected or not.
The value of the index n°141 is the time, expressed in seconds, after which the connection to the BMS is no

longer considered active, the SCMQ10 shows an alarm A 62 and the A-M parameter of all the network
devices connected to the terminal SCMQ10 is automatically fixed to oFF. When the value of the index n°141

becomes ≠ 0, BMS connected, the BMS must set again the A-M value of all the network devices, if

different from oFF .

To avoid this alarm write cyclically, before it expires, the value of the BMS time-out on the index 141.
For example: if you want that the BMS connection becomes invalid after 10 minutes, 600 seconds, write 600
on the index 141 at least every 5minutes / 300 seconds

1 = MODBus always disabled. Change of the parameters of the devices are allowed only by SCMQ10,

anyway you can read the parameters both by SCMQ10 and MODBus;

connection"; DO NOT SWAP +A / –B WIRES.
11
- MAKE A LINEAR NETWORK CONNECTION: NOT STAR, RING OR TREE.
12
- MAKE SURE THE REMOTE CONTROLS ARE CONNECTED AND SUPPLIED, BEFORE
13
PROCEEDING.
- CONNECT MAX 16 ZONE MODULES TO THE SCMQ10. ADDRESSES FROM 0 TO 15.
At the SCMQ10 first start up the master device shows for ~5s. the clock, for
ex.: 8:10, Monday. (1 = Monday; 2 = Tuesday;...7 = Sunday).
If the clock is not correct set it correctly. To change/set the clock and the
calendar see the paragraph n° 5.1 : CLOCK / CALENDAR SETUP.
Should the device lack of a previously acquired network, an acquiring
process will automatically after the clock visualization i.e. at the SCMQ10
start up . Now the SCMQ10 shows the
At the end, the display shows the list of the acquired devices:
