3.18 - HYDRAULIC AND ELECTRIC SYSTEM CONNECTION WITH PANEL BOARD
code 37892
Fig. 24 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:
M = flow
Rat = HIGH temperature return
Rbt = LOW temperature return
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 board code 37892.
IMPORTANT NOTE: when there is only one zone (high or low temperature) always insert the
system return pipe in the lower rear connection.
