NRC-6-SV Room Thermostat and Remote Control Module
Introduction
The Add t onal “Control module” NRC-6 w th software vers on SV s ntended to
work w th the NPBC-V3C-1 controller, wh ch s composed of a NPBC-V3M ”Execut ve
module” and a NRC-6-MV ma n “Control Module.” If the assembly s executed on NPBC-
V3M , t s connected n parallel to the ma n control module to ts second connector (type RJ
11) or by a coupler nto the RJ 11 connector. The add t onal control module d splays the most
mportant nformat on about the burner’s state and ts operat ons: operat on stage, errors
reg stered, the parameters measured by the sensors, and the current state of the t mers.
Add t onally, the NRC-6 SV module works as a room thermostat and measures the amb ent
temperature w th a temperature sensor, wh ch s connected to the box (connected w th a w re).
The screen’s graph s des gned a l ttle s mpler and t has a ded cated new blue f eld where the
amb ent temperature s shown. The add t onal control module has l m ted control funct on
compared w th NPBC-V3C-1/2 controller. The follow ng opt ons are ava lable: sw tch ng on,
off or to t mer mode, fuel type select on, adjustable sett ngs for the burner t mers, and clock
adjustment. The add t onal controller module has several sett ngs regard ng ts funct on as a
room thermostat: sett ng and ma nta n ng a des red room temperature, as well as the opt on for
t mer sett ngs, wh ch g ves the opportun ty to set d fferent temperatures dur ng the day.
The rest operat on parameters cannot be set from NRC-6. The temperature adjustment
funct on refers to the amb ent temperature, not to the bo ler temperature.
