13. Стр. 14 N.B.: if the heating system has a RVA47 regulator for control of a system with cascade-connected

    boilers, set the clock of the RVA47 as MASTER clock (see instructions supplied with the regulator itself). The time, day and year must only be set on the MASTER regulator. All the RVA 46 devices connected to the MASTER are updated automatically. 6. Setting the RVA46 parameters for the type of room…

14. Стр. 15 To set the heating curve, proceed as follows

    Select program line n° 17. Press the +/- keys to set the curve required (factory setting = 15). For low temperature heating systems (e.g. underfloor systems), set a low gradient curve. N.B.: if the QAA50 digital room unit is connected to the system, the RVA 46 regulator will adapt the curve…

15. Стр. 16 8. System delivery temperature minimum and maximum threshold

    The minimum and maximum thresholds set the range within which the delivery temperature is permitted to vary, in order to prevent excessively high or low delivery temperatures. To set the thresholds, proceed as follows: Select program line n° 68. Press the +/- keys to set the delivery temperature…

16. Стр. 17 10.2 Setting the system type

    The electronic circuit board must be set up for the type of system present. Select program line n° 552 as described in the previous point; Press the +/- keys to set the boiler's water system type (see table). Level Parameter N. Description H 552 System setting Factory setting single purpose dual…
