CTC EcoZenith i550 Pro
For the property owner
Test frequency min. 30 (0 to 180)
Specifies the frequency at which the Solar Test function
should perform. If set value is 0 the solar test is
constant.
Winter mode Off (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 bore hole only.
“No” Permits the Solar Test Tank function, and charging
of the EcoZenith is possible.
Protection Collector
Max. temp. °C 120 (110 to 150)
Protects the solar panels from high temperatures by
allowing circulation in the solar panels even though
the maximum temperature has been reached in the
respective tank. For safety reasons, the temperature in
the EcoZenith is never allowed to exceed 95°C.
Cooling No (Yes/No)
Permits circulation to the EcoZenith as well as the
bore hole. This is in order to prevent excessively high
temperatures in the solar panels. Applies once the
maximum permitted temperature has been reached.
For safety reasons, the temperature in the EcoZenith is
never allowed to exceed 95°C.
Re-cooling No (Yes/No)
This option may be activated when the cooling function
has been activated. The function means that the system
endeavours reduce the temperature in the hot water and
buffer tank to the set setpoint (set in the
Re-cooling to
temp.
menu). This means that the solar panels are used
as cooling elements for a short period of time.
Re-cooling to temp. °C 70 (50 to 80)
This option may be activated when the Re-cooling
function has been activated. The function means that
the system endeavours reduce the temperature in the
hot water tank and buffer tank to the set setpoint.
