3.24 - HYDRAULIC AND ELECTRIC SYSTEM CONNECTION WITH PANEL
BOARD code 38778
fig. 31
Fig. 31 shows the typical layout of the connection of the boiler to the heating system consisting in 1 direct high temperature zone
+ 1 low temperature zone controlled by a motorised mixer valve + domestic hot water production.
Key:
Vmix2 = zone mixer valve (motorised)
Pz1 = HIGH TEMPERATURE zone heating system pump
Pz2 = LOW TEMPERATURE zone heating system pump
VE = expansion vessel
IR/AT = HIGH TEMPERATURE heating system distribution
IR/BT = LOW TEMPERATURE heating system distribution
Ps = DHW recirculation pump
Pb = DHW production charge pump
SPF = storage tank probe
KF = E8.5064 heat control boiler probe
KF 1= Lago Basic 0201 RV 1 heat control boiler probe
VF = flow probe
AF = external probe
For practical connections, both electrical and of the probes, see the diagrams supplied with the
panel boards code 38778.
IMPORTANT NOTE: when there is only one zone (high or low temperature) always insert the
system return pipe on T2 Low temperature C.H. return connection .
