Before explore into the description and functions of the various subsystems, it is appropriate to introduce a general concept that applies to the entire REG System, that of the input multiplexer.
...
The REG System is totally flexible from this point of view, and allows the signal to be connected to whatever input of the boards constituting the system.
ANALOG INPUT SELECTOR
Note
The following examples and images are taken from the RegConfig software, but the same settings can also be made from the LCD display of the REG-DIN-8 board. At all points of the configuration where a temperature (and humidity) value should be (or must be) acquired, there is a drop-down menu which will be illustrated below.
...
Passive Probes
Each probes require a direct 2-wire connection between the probe and the board.
Each probe uses an analog input of the board REG-DIN-8 or of an expansion board; the total number of passive probes connected to a system is therefore limited by the number of available inputs;
Passive probes do not require addressing.
Active Probes
They use a 4-wire (+,-,A,B) connection from the board and connect the active probes in connection, with an “in-out” wiring.
The probes are connected to the BUS terminal of the board, they do not use analog input.
The active probes must be addressed, that is each one must be assigned an address that allows the board to communicate with the various active probes connected to the BUS.
PHOTO TBD
Understood the distinction between active and passive probes, it is easy to understand how to configure the parameters that allow you to set the probe for the various zones, systems and outdoor probes:
...
The first part of the field allows you to select from which board to acquire the sensor value from. The drop-down menu lists all the boards that could potentially be present in a system:
PHOTO TBD
therefore from the board REG (REG-DIN-8) to the expansions EXP (REG-EXP-8), IOA and IOB (REG-IOA and REG-IOB).
...
It is also possible to use the virtual analogue readings acquired from UGW via Modbus directly from the device being managed (for more information, see the REG-UGW-485 Manual).
PHOTO TBD
In addition to the boards, it possible to directly select the sensor managed via REG bus:
...
If the REG-DIN-8 (REG), REG-EXP-8 (EXP x), REG-IOA, REG-IOB (IOA x / IOB x) or REG-UGW-485 (UGW x) boards have been selected, the Channel field allows you to specify which input, among those available on the selected board type, to use for the reading; the list that appears automatically adapts to the selected board, listing the available channels; for example, in the case of EXP board, 8 channels appear; if an IOA type board is selected, only two channels are displayed:
PHOTO TBD
PHOTO TBD
If the REG-AQ-Sxx (AQ) bus sensor were selected, the channel field must be left at s/set as default, which means that the sensor has no display:
PHOTO TBD
For temperature and humidity sensor (from T160 to TH 223) you must select s/set if they are REG-TH-Sxx sensor, without display and therefore without the possibility of changing setpoint. If c/set is selected, this means that a REG-THL-Sxx sensor with display has been installed.
...
TEXT G2/G0 and TEXT G1 = takes the outside temperature value passed by the G0 or G2 and G1 generator (an Opentherm generator must be connected to use this)
TMAND G1 and TMAND G2/G0 = takes the water outlet temperature value passed by the G0 or G2 and G1 generator (an Opentherm generator must be connected to use this)
TRIT G1 e TRIT G2/G0 = takes the water inlet temperature value passed by the G0 or G2 and G1 generator (an Opentherm generator must be connected to use this)
DHW = this value is only displayed for the sensor on the DHW page and corresponds to the DHW temperature passed by the G0 generator (an Opentherm generator must be connected to use this and a DOT display with Opentherm on board must be used)
TDHW Gx = takes the DHW temperature value passed by the Gx generator (an Opentherm generator must be connected to use this)
HOST = TBD
100%rh = a value of 100% relative humidity is displayed
MATHx = takes the value of the result of the corresponding mathematical operation (see MATH FUNCTIONS)
?25 up to ?95 = TBD
SET Zx = takes the current zone setpoint set point as the temperature value
n/u = not used

SENSOR TYPE FIELD
The third field allows you to specify the various types of NTC sensor that REG System boards are capable of acquiring:
PHOTO TBD
D = Default, indica il riferimento per la scheda, per il sistema REG indicates the reference for the board, for the REG System, default = M
M = sonde NTC 12kOhm Beta 3977 (prodotti con queste caratteristiche probes (products with these characteristics are STM/STB/STE/TP-Sxx)
A = sonde NTC 10kOhm Beta 3970 (prodotti con queste caratteristiche probes (products with these characteristics are STA)
S = sonde NTC 10kOhm Beta 3435 (prodotti con queste caratteristiche sono probes (products with these characteristics are OEM)
L = è una lettura lineare, cioè normalizza i valori letti dall’ingresso da 0 a 100 (si utilizza in casi particolari e su indicazione del produttoreis a linear reading, that is it normalizes the value read from the input from 0 to 100 (it is used in special occasions and to the manufacturer’s instruction)
R = Valore Raw (grezzo) sono valori non rielaborati acquisiti in situazioni specifiche, se serve, come nel caso in cui si utilizzi il REG2VFS, è specificato nella scheda tecnica del prodotto
SELETTORE INGRESSO DIGITALE

La prima parte del campo permette di selezionare da quale scheda acquisire lo stato dell’ingresso digitale (0 o 1). La tendina elenca tutte le schede che possono potenzialmente essere presenti in un impianto:

Raw value are unprocessed value acquired in specific situations, if needed, as in the case of using the REG2VFS, it is specified in the product data sheet.
DIGITAL INPUT SELECTOR
BOARD FIELD
The first part of the field allows you to select from which board to acquire the digital input status (0 or 1). The drop-down menu lists all the boards that can potentially be present in a system:

then from the REG (REG-DIN-8) alle espansioni board to the expansions EXP (REG-EXP-8), IOA e and IOB (REG-IOA e and REG-IOB).
Per i For REG-IOC selezionare da select from IOB 92 a to IOB 99 (vedere scheda tecnica del see REG-IOC data sheet).
E' possibile utilizzare anche le letture digitali virtuali acquisite dagli UGW via Modbus direttamente dalla periferica che si sta gestendo (per maggiori informazioni vedere il It is also possible to use the virtual digital readings acquired by the UGW via Modbus directly from the device being managed (for more information, see the REG-UGW-485 _ManualeManual).

In fondo alla tendina è possibile selezionare 3 opzioni particolari:
VDoutL = corrispondono agli stati delle uscite digitali disponibili nel Sistema REG dalla zero alla 127, per questo L che sta per Low cioè i valori più bassi (e i relativi negati). Vedere CONFIGURAZIONE DEGLI OUTPUT VIRTUALI
VDoutH = corrispondono agli stati delle uscite digitali disponibili nel Sistema REG dalla 128 alla 255, per questo H che sta per High cioè i valori più alti (e i relativi negati). Vedere CONFIGURAZIONE DEGLI OUTPUT VIRTUALI
AlarmDout = corrispondono agli stati degli allarmi disponibili nel Sistema REG
...
At the bottom of the drop-down menu, you can select 3 particular options:
VDoutL = corresponds to the states of the digital outputs available in the REG System from zero to 127, for this L stands for Low, that is the lowest values (and their negatives). See VIRTUAL OUTPUT CONFIGURATION
VDoutH = corresponds to the states of the digital outputs available in the REG System from 128 to 255, for this H stands for High, that is the highest values (and their negatives). See VIRTUAL OUTPUT CONFIGURATION
AlarmDout = corresponds to the alarm states available in the REG System
CHANNEL FIELD
Se sono state selezionate le schede REG-DIN-8 (REG), REG-EXP-8 (EXP x), REG-IOA, REG-IOB (IOA x / IOB x) o REG-UGW-485 (UGW x) il campo Canale permette di specificare quale ingresso, tra quelli disponibili sul tipo di scheda selezionata, utilizzare per la lettura dello stato; l'elenco che compare si adatta automaticamente al tipo di scheda selezionata, elencando i canali disponibili; per esempio nel caso della scheda EXP compaiono 8 canali; se si seleziona una scheda di tipo IOB, vengono visualizzati solo due canali:

Come si può notare dalle foto il contatto digitale può essere preso sia come normalmente aperto (IAx) che come normalmente chiuso (/IAx) per soddisfare le molteplici esigenze impiantistiche.
Nel caso si sia scelto VDout L o VDout H il campo canale si popolerà in base alla regolazione che è stata eseguita salvo le prime 13 uscite digitali:

Nel caso si sia scelto AlarmDout il campo canale si popolerà con tutti gli allarmi disponibili all’interno della regolazione del Sistema REG:

Ovviamente funzioneranno o meno in base alla programmazione del caso specifico.
