CTC EcoZenith

I

550

dT setpoint low °C

Setting of the number of degrees that the lower tank of the CTC EcoZenith

I

550

must exceed its reference value to start transfer to the external buffer tank. This
setting applies to charging of solar energy when a heating need is present on the
radiator system.
Factory value 7°C (setting 2-50°C).

HP charging

Charging the external buffer tank with heat from the heat pump is especially
interesting when there are different power rates during the day. The buffer tank(s)
can then be charged when the power rate is low. The lower tank of the CTC
EcoZenith

I

550 will work towards the set temperature during those periods which

are scheduled in the “Day by Day” menu and then transfer heated radiator water
to the buffer tank(s), provided that it has a lower temperature. Factory value Off
(setting Off, 20-60°C).

Week prog.

In this menu the charging of the external tank is scheduled.

Week program Menu

(Installer/Settings/Ext storage tank/ Week porg.

)

In this menu the charging of the external storage tanks during the weekdays
is scheduled. The schedule is repeated every week. The illustration shows
the factory values to be changed.

In this menu settings for the pool operation are made

Pool temp °C

Stop temperature for the pool: at this set temperature the charging of the pool
is halted. Factory value 22°C (setting 5-50°C).

Pool diff °C

This value indicates how much the temperature is allowed to fall below the
“Pool temp °C” before the charging of the pool starts again. Factory value 1.0°C
(setting 0.2-5.0°C).

Pool priority

“High” The pool is allowed to take so much heat that additional heat is activated.
“Low” The pool is not heated when additional heat is activated.
Factory value High (setting High/Low).
