CONNECTION TO SOLAR CIRCUIT (SOL VERSION)
SOL range units are designed for the production of domestic hot
water in conjunction with a solar system . The incorporated solar heat
exchanger enables the connection of solar collectors as given in the
table below. The unit's electronic regulation can control the fundamental
elements of the solar system .
Connect the solar circuit inlet at the place on the tank indicated
[SOLAR WATER INLET] and the return to the solar panel at the place
indicated [SOLAR WATER OUTLET]
The diagram opposite shows the recommended connection
A= Solar collector
B=solar circuit pump (managed by unit)
C=excess heat dissipating valve (managed by unit)
D=expansion tank
E=safety valve
F=shutoff valves
G=one-way valves
H=collector temperature sensor (supplied with unit)
IN=Coil inlet
OUT=Coil outlet
