To use this function, it is necessary to have at least firmware version 4.30 on the REG-DIN-8 and to use a RegConfig version 4.30 or later.
...
The REG System provides up to 8 Dehumidifier/Integration units, therefore, if in a system there are up to 8 fan coils, in as many rooms it is possible, for each zone, to manage a fan coil, using the Dehumidifiers page used as Integration, independently. For example, if there are 4 zones each with a fan coil for heating and cooling (or only cooling), each zone will be associated with a Dehumidifier in the Integration column:
PHOTO TBD
In the Dehumidifier page, on each sub page D1, D2, D3, and D4 will be set:
Integration control “Active if requested” in summer and winter (if the room is to be both heated or cooled)
Valve control “Active if requested” if the Circuit is associated in the Dehumidifier page, if it is associated in the Zone page the Valve control may be left off
“Associated circuit” if managed from the Dehumidifiers page
The values in % of the low, medium, and high speeds of the Integration flow rates
PHOTO TBD
Low, medium, or high speed of each fan coil depends on the integration offset set in Configuration 2:
PHOTO TBD
Therefore, if the difference between the temperature read by the sensor of each zone and the set point set exceeds 1 K, the fan coil speed will be low, if it exceeds 2 K it will be medium and if it exceeds 3 K it will be high.
In the REGDIN OUTPUT page, the Analog Outputs to be connected to the 4 fan coils are the speeds of each dehumidifier (used as Integration) independent of each other:
PHOTO TBD
If the fan coils are more than 8, it is no longer possible to follow this path.
...
Assume having 10 rooms, each of which is heated and cooled by 1 fan coil, which are associated with the zone in the Integration column:
PHOTO TBD
The REG System can manage maximum 8 fan coil speed groups, as 8 are the available Dehumidifier/Integration units to rely on, therefore in the case at hand it is necessary to identify two pairs of room in which, reasonably, it is possible to manage with the same speed fan coils which are not in the same room, in the example are defined:
Living Room and Hall → Integration 1 (1 fan coil for each zone)
Kitchen → Integration 2 (1 fan coil)
Room 1 → Integration 3 (1 fan coil)
Room 2 → Integration 4 (1 fan coil)
Room 3 → Integration 5 (1 fan coil)
Dining Room → Integration 6 (1 fan coil)
Bathroom 1 e Bathroom 2 → Integration 7 (1 fan coil for each bathroom)
Study → Integration 8 (1 fan coil)
Note
In questo esempio non è previsto che unità di deumidificazione/integrazione possano essere utilizzate per altro (ad esempio una VMC). Ma nel caso in cui le unità di deumidifica e integra disponibili fossero meno di 8 è necessario unificare il più possibile i fan coil che hanno la stessa mappatura tra velocità e volt. Quindi se si ipotizza che due unità di deumidifica/integra siano già impegnate i 10 fan coil dell’esempio potrebbero essere raggruppati come segue:
Soggiorno e Ingresso → Integrazione 1 (1 fan coil per ciascuna zona)
Cucina → Integrazione 2 (1 fan coil)
Camera 1 / 2 / 3 → Integrazione 3 (1 fan coil per ogni camera)
Bagno 1 e Bagno 2 → Integrazione 4 (1 fan coil per ciascun bagno)
Sala da pranzo → Integrazione 5 (1 fan coil)
Studio → Integrazione 6 (1 fan coil)
è infatti ragionevole ipotizzare che stanze con la stessa destinazione d’uso possano condividere la stessa mappatura di velocità dei fan coil.
In this example it is not provided which dehumidifier/integration units can be used for anything else (e.g., a VMCventilation unit). But, if the available dehumidification/integration unit are less than 8, it is necessary to unify as much as possible the fan coil that have the same mapping between speed and volts. Therefore, if it is assumed that two dehumidification/integration units are already occupied, the 10 fan coils in the example could be grouped as follows:
...
le Portate d’aria dell’Integrazione in % da 0 a 100 in bassa, media e alta velocità
Setting the fan coil speed groups
In the fan coil speed group of dehumidifier 1 on the Dehumidifier D1 page, it is only necessary to set:
· The Air Flow Rate of the Integration in % from 0 to 100 in low, medium and high.
PHOTO TBD
Le portate d’aria possono essere tutte diverse in base alle esigenze del singolo gruppo di velocità di fan coil. Ad esempio nella camera 1 le portate sono più basse rispetto al gruppo Soggiorno/Ingresso:
The Air Flow Rate can all be different depending on the requirements of the individual fan coil speed group. For example, in Room 1 the flow rates are lower than in the Living Room/Hall group:
PHOTO TBD
Se due zone si appoggiano alla stessa unità di Integrazione per prendere il valore 0/10 di velocità non è detto che la velocità a cui vengono gestiti i fan coil sia la stessa.
...
quindi il fan coil del Soggiorno andrà a velocità bassa (4 V - 40%) perché il delta è compreso tra 2 (offset di media velocità) > 1,9 K > 1 K (offset di bassa velocità), mentre il fan coil dell’ingresso andrà a velocità alta (9 V - 90%) perché il delta è 4,5 K > 3 K (offset di alta velocità).
If two zones rely on the same Integration unit, to take the 0/10 speed value, it is not certain that the speed at which the fan coils are operated are the same.
Let us take the example of the Living Room and Hall zone from the image; in point 2 we can notice that:
· The temperature read by the sensor in the Living Room is 28,9°C with set point 27°C → delta = 1,9 K
· The temperature read by the probe in the Hall is 30°C with set point 25,5°C → delta = 4,5 K
Therefore, the Living Room fan coil will run at low speed (4 V – 40%) because the delta is between 2 (medium speed offset) > 1,9 K > 1 K (low speed offset), whereas the Hall fan coil will run at high speed (9 V – 90%) because the delta is 4,5 K > 3 K (high speed offset).
4. Assegnare le uscite 0/10V
Nella pagina Uscite REGDIN le Uscite Analogiche da collegare ai 10 fan coil non sono più le velocità di ciascun deumidificatore (utilizzato come Integrazione), ma il valore 0/10 trasmesso da ogni singola zona, che corrisponde al valore 0/10 della velocità (alta/media/bassa definita dalla zona) presa dall’unità di integrazione associata alla zona stessa:
Assigning 0/10V Outputs
On the REGDIN Outputs page, the Analog Outputs to be connected to the 10 fan coils are no longer the speeds of each dehumidifier (used as Integration), but the 0/10 value transmitted from each individual zone, corresponding to the 0/10 value of the speed (high/medium/low defined by the zone) taken from the integration unity associated with the same zone:
PHOTO TBD
Quindi nella pagina Uscite REGDIN si associa ad esempio:
...
Un impianto di questo tipo necessita di molte uscite 0/10V (tante quante sono i fan coil installati), quindi si consiglia di utilizzare i moduli REG-IOC, che hanno 2 uscite analogiche 0/10V ciascuno e possono essere impostati nella pagina Uscite IO/B dal numero 92 a 99:
Therefore, on the REGDIN Outputs page, is associated with, for example:
· UA1/0: set point zone 1 (Living Room) to be connected with the 0/10 V input of the fan coil of the Living Room
· UA2/0: set point zone 2 (Kitchen) to be connected with the 0/10 V input of the fan coil in the Kitchen
· UA1/1: set point zone 3 (Room 1) to be connected with the 0/10 V input of the fan coil in the Room 1
· UA2/1: set point zone 4 (Room 2) to be connected with the 0/10 V input of the fan coil in the Room 2
A system of this type requires many 0/10 outputs (as many as the installed fan coils); therefore, it is advisable to use the REG-IOC modules, which have 2 0/10V analogue outputs each and can be set in the IO/B Output page from number 92 to 99:

Attenzione
Attualmente anche se viene mostrato il valore NC (Non Configurato) le funzione è comunque attiva, per verificare il voltaggio in uscita è necessario utilizzare un tester.
Si allega il preset dell’esempio riportato:
Warning
Currently, even if the NC (Not Configured) value is shown, the function is still active; to check the output voltage it is necessary to use a tester.
Attached is the example preset:

...
Ad esempio se la zona 10 (Studio) avesse 2 fan coil la pagina Uscite IO/B dedicherebbe 2 uscite analogiche alla zona 10:
Finally, if there is more than one fan coil in a room, it is enough to repeat what has been shown so far, simply associate the 0/10 value of the zone/room that has more fan coils with more analogue outputs (depending on how many fan coils there are).
For example, if the zone 10 (study) had 2 fan coils, the IO/B Output page would dedicate 2 analogue outputs to zone 10:
PHOTO TBD
E' evidente che in questo caso essendo il sensore ambiente lo stesso, le uscite UA2/94 e UA1/95 avranno sempre lo stesso valore e i due fan coil lavoreranno alla stessa velocità.
It is obvious that, in this case, since the room sensor is the same, UA2/94 e UA1/95 outputs will always have the same value and the two fan coils will work at the same speed.
