14.3.3 CTC EcoZenith i555 Pro – Solar heating

Solar panels (17) can be connected directly to the EcoZenith’s built-in solar

coil (11).

The solar coil is the finned type. The fluid is pumped from the coil by a speed

controlled solar pump (G30). In a larger system with several solar panels of

more than about 10 m², the panels are connected to an intermediate heat

exchanger (05) and the changing solar energy is pumped to the EcoZenith’s

lower tank by a speed controlled pump (G32). The pumps are powered by a

separate source and their speed is controlled by the EcoZenith. Refer to the

"Electrical installation" chapter for more information.

The 3-way valve (Y31), plate heat exchanger (18), charge pump for

recharging boreholes (G31) and non-return valves (36) and (41) are used

for recharging boreholes/energy wells with solar energy. The EcoZenith also

starts the brine pump in the liquid/water heat pump (CTC EcoPart) when

recharging is taking place. This means that the charge pump for recharging

the borehole (G31) is then needed to compensate for the pressure drop

across the plate heat exchanger (18), thus ensuring, in combination with the

brine pump, sufficient flow through the heat collector and exchanger.

Speed controlled pumps (G30), (G31) and (G32), 3-way valve (Y31) and plate

heat exchanger (05), (18) are CTC accessories.

Also refer to the "Solar panels" section in the "Detailed Menu Descriptions"

chapter (Installer/Settings/Solar Panels).
