In any event, the THR 10-100 can be replaced with
a set of THR 10-100s in a cascade (4 maxi.). Do-
mestic hot water production is ensured in the same
way, i.e.:
- either by the domestic hot water load pump on the
network (via the RVA 47),
• The domestic hot water sensor and the load
pump can be connected to any RVA 47 in the
cascade.
• The domestic hot water request and the d.h.w.
setting may be set on
WKLV59$
. (paragra-
ph. 2 - section V - BASIC SETTING OF THE
THR 10-100).
- or by a selector valve (controlled by a BMU) with
a THR 10-100 CS within the cascade.
• This domestic hot water production is only pos-
sible if at least one domestic hot water tank is
connected to a THR 10-100 CS within the cas-
cade.
• The domestic hot water request and the d.h.w.
setting may be set
5 &6
.
• Several tank connection cases are possible
(paragraph 3 - section V - BASIC SETTING OF
THE THR 10-100).
The cascade operation is the same as with a single
THR 10-100. Selection/Deselection of the LGMs
identical see paragraph 7.2.5 - section VI - COM-
MISSIONING
Note:
- The buttons of the heating regime, the automatic
regime, the permanent regime and the standby
of the slave RVA 47s are inactive. The d.h.w. re-
gime button is only active on the
THR 10-100 CS or on the THR 10-100 C to which
a d.h.w. sensor is connected (Terminal B3 of the
RVA 47).
