70 CTC EcoZenith i555 Pro
Solar test tank min 4 (1...20)
(Used only if evacuated tube solar collectors have been
defined.)
Once every 30 minutes (factory setting) to check
whether tank charging is possible. The test is carried
out at the set time interval. If sufficient temperature
is obtained, tank charging continues; otherwise the
system switches to charging the bedrock again.
Test frequency min 30 (0...180)
Specifies the frequency at which the Solar Test function
should perform. With 0 as the set value, solar test takes
place continuously.
Winter mode (Off/On)
Winter mode is a setting which does not permit the
EcoZenith to check whether charging of solar energy to
the lower tank is possible.
In winter, the EcoZenith normally retains a higher
temperature and the sun emits less energy and lower
temperatures. To check whether charging of solar
energy to the tank is possible, water must circulate in
the system and the temperatures must be compared. If
the check indicates that charging is not possible, energy
will have been used unnecessarily by having the water
circulate. The winter mode setting prevents this check.
"Off" deactivates the Solar Test Tank function. Charging
is carried out to the bedrock only.
"On" Permits the Solar Test Tank function and charging
of the EcoZenith is possible.
Flow l/min 6.0 (0.1...50.0)
The flow circulating through the solar panels should be
indicated here. (This can be read from the flow meter in
the system unit.) The flow should be read when pump
G30 is running at 100%.
NB! It is important the value is correct, as the flow
is used as the basis for calculating the power and
cumulative energy. Incorrect flows will therefore produce
incorrect values for these parameters.
