Upper Tank Menu
(Installer/Settings/Upper Tank)
In the “Upper Tank” menu you make settings which affect the operation
of the upper part of the CTC EcoZenith
I
550 tank.
Stop temp °C
Here you set the temperature at which the charging of the upper tank is stopped.
A temperature set higher provides better hot water capacity but worse operating
economy.
Factory value 50°C (setting 40 up to the “HP1, max prim. flow” menu).
Max time upper tank
This is the time in minutes that the upper tank is allowed to be charged, without
reaching its reference value, before the CTC EcoZenith
I
550 starts charging the
lower tank in case of heating needs. A longer set time means that hot water is
prioritized for a longer period. Applies only when a heat pump is connected.
Factory value 20 min (setting 0-60 min).
Maxtime low. tank
This is the time in minutes that the lower tank is allowed to be charged for the
radiator needs, without reaching its reference value, before the CTC EcoZenith
I
550
starts charging the upper tank in case of warm water need. A longer set time
means that heat is prioritized for a longer period.
Applies only when a heat pump is connected.
Factory value 40 min (setting 10-120 min).

Mixing valve del
Here you set the mixing valve delay before it takes energy from the upper part of
the tank, the additional heating part. The mixing valve can be blocked so that it
never retrieves energy from the additional heating part of the tank. Factory value
180 min (setting 30-240 min and blocked).
Main fuse A
The main fuse size is set here. Together with installed current sensors, the fuses are
protected when using machines which give temporary power peaks, e.g., stove, oven,
engine heater, etc., whereupon the product temporarily reduces the connected output.
Factory value 20 A (setting 16-100 A).
Supply voltage
Setting of the grid supply voltage, for instance, 3x400 V (applies in Sweden)
Tariff el.
Here it is indicated if the product is connected to tariff-controlled electricity.
This does not apply in Sweden.
