återfinns i kablagets nedre del, bakom fronten. För att ställa reservvärmestermostaten i
frostskyddsläge vrid moturs så långt det går så att mejselspåret står vertikalt (off-läge), vrid
sedan tillbaka medurs tills mejselspåret står i linje med figuren för frostskydd (ca 1/8 varv).

16. First start
When the CTC EcoZenith i250 is delivered, the heat pump is blocked to avoid it
being started unintentionally. EcoZenith I250 can be installed and started before
the bedrock/ground source or air/water heat pump is put into operation.
The EcoZenith i250 can also be started without a room sensor being fitted as
the curve which has been set then regulates the heating. Deselect the room
sensor in the Settings menu. The sensor can however always be fitted for the
alarm LED function.
Before first start
1. Check that the EcoZenith I250 and system are full of water and have been
bled.
(The EcoZenith i250 is bled through the safety valve on the top cover of the
product.)
2. Ensure that, where applicable, the brine system is filled with water and anti-
freeze and that it is bled, or ensure that the compressor is blocked.
(This applies when docking with the CTC EcoPart 400.)
3. Check that all connections are tight.
4. Check that sensors and the radiator pump are connected to the power
source.
5. The backup heating thermostat has OFF as its factory setting. The recom-
mended position is
= Antifreeze setting, around +7°C. The backup heat-
ing thermostat is reset on the electrical switchboard behind the front panel.
It is in the OFF position when it is turned anticlockwise as far as it will go (the
screwdriver slot should be vertical).
NB: At the end of the installation, check the current transformers’
connection. In this situation it is important that you have switched off
any major consumers of electricity in the house. Also make sure that the
backup thermostat is turned off.
