RB100 : Installation and Use Manual
10 Ed. 06/2014 – FW version 1.002
Operation of services
As already said before, the interface device can receive, for each one of four services
available, an analogue (0-10 V) or digital (clean contact) input signal. For each request
received on input, the appliance sends a proper request to DDC; to this point, the Direct
Digital Controller is in charge of machine management to meet such request.
The following services are available on each RB100 interface device:
Cold service:
when an input signal is received on this service, the appliance provides for
a DDC request, so that DDC can control the turning-on of cold modules on the plant and
properly manage them to meet such request;
Hot service:
when an input signal is received on this service, the appliance provides for a
DDC request, so that DDC can control the turning-on of hot modules on the plant and
properly manage them to meet such request;
DHW0 and DHW1 service:
when an input signal is received on these services, the
appliance provides for a DDC request, so that DDC can control the turning-on of hot
modules on the plant and properly manage them to meet such request. Especially, each
service can be configured so that separable sanitary-type requests or basic plant sanitary
–type requests can be made;
Valve service:
this service is used to control three-way motorized valve, allowing for
management of hydraulic separation of unit separable from the basic unit or switching
plant operation from heating to cooling and vice versa.
During the switching phase, the valves installed must ensure the minimum flow
specified in Table 3.
