CTC EcoZenith i250
General Information
Factory settings coded
This menu is intended to set the manufacturer’s
operational and alarm limits. A 4-digit code must be
specified to be able to amend these limits. However,
you can also take a look without any code to see what
options feature in the menu.
!
NB: Only an authorised service engineer is allowed to log in to the Factory settings
coded option. Severe operational problems and faults may occur affecting the
product if values are amended without authorisation. Note that in such cases the
warranty terms do not apply.
Quick start compressor
(Applies only if heat pump is installed.)
When starting up the product, the compressor’s start
is delayed by 10 minutes. This function speeds up this
process.
Software update, USB
This is only for service engineers. This option can be
used to update the software in the display via USB. The
software update process is complete when the start
menu appears.
Write log to USB
This is only for service engineers. This function can be
used to save logged values to a USB memory stick.
Control current sensors
This is for identifying which current sensor is connected
to the relevant phase.
All three currents (L1, L2 and L3) will appear in the
current operational data when EcoZenith i250 has
identified the current transformers’ relevant phases.
When activating the function “Control current
sensors” it is important that you have switched off
any major consumers of electricity in the house.
Also make sure that the backup thermostat in CTC
EcoZenith i250 is turned off.
Re-installation
This command re-launches the installation sequence.
See the chapter on First start.
!
NB: The power to the product
must not be interrupted, under any
circumstances, during the update
process.
