CTC EcoZenith i250
General Information
10. Troubleshooting/measures
!
Avoid running hot
water at the highest
flow capacity. If you
run a bath at a rather
slower rate instead,
you will get a higher
temperature.
!
Avoid placing the
room sensor close
to the stairway due
to the uneven air
circulation.
!
If you do not have
radiator thermostats
on the upper floor,
you may need to
install them.
The CTC EcoZenith i250 is designed to provide reliable operation and high
levels of comfort, and to have a long service life. Various tips are given
below which may be helpful and guide you in the event of an operational
malfunction.
If a fault occurs, you should always contact the installer who installed your
unit. If the installer believes the malfunction is due to a materials or design
fault, then they will contact us to check and rectify the issue. Always provide
the product’s serial number.
DHW
Many people want to gain maximum benefit from the CTC EcoZenith i250’s
low operating costs.
The control system is equipped with three comfort levels for hot water. We
recommend starting at the lowest level and if there is not enough hot water,
increase it to the next level. We also recommend that you operate a regular
hot water pattern.
Check that the hot water temperature is not being affected by a poor mixing
valve, whether in the CTC EcoZenith i250 or possibly the shower mixer.
The Heating System
A room sensor, which should be fitted when possible, ensures that the
temperature in the room is always suitable and stable. For the sensor to
provide the correct signals to the control unit, radiator thermostats should
always be fully open in the area where the room sensor is located.
A correctly operating heating system is of significant importance to the heat
pump’s operation and affects energy savings.
When adjusting the system, always do so with all radiator thermostats fully
open. The thermostats can be individually adjusted after a few days in the
other rooms.
