5.19 FRESH AIR PROBE
ONLY FOR UNIT IN DUCTABLE VERSION
It is shipped inside the unit : it must be mounted outside and
cabled .
The sensor doesn’t have to be influenced by elements that
can distort the reading ( for example direct solar irradiation,
contact with heat sources, accumulations of snow/ice )
CABLE : Max. distance 50 mt , 2x0,34mm
2
+ shield ( to
connect to the ground ) .

G - CHOISE OF THE OPERATING MODE
To choose the working mode press for few seconds the
button…..…..
Off: system off, the panels and the unit are always
off
Economic: system always on, the air set-point is
economic
Comfort: system always on, the air set-point is normal
Automatic: the system is switched on anf off following the
time scheduling
Party: the system is forced at the start-up for
30’ (configurable) by an appropriate ambient
set modifiable rotating the central button. At
the time expiration, the system will be back at
the previous status.
The function operates on the zones only if
they are enabled to party by the setting (5.3).
Indicated if you want to heat or cool the house
on occasion of an event, the time can be
modified by parameters (configuration ->
keypad -> setup -> Id60 ). Party is a function
for advanced users
H - MIXER CONTROL
Mixer not supplied by Clivet (PECZ0013)
password -> Maintenance man (115) -> configuration ->
system -> Unit inquiry
• Device Id = 50
• Address: 1084
• Value: enter travel time of the mixer valve
If the valve is unstable, or it continues to open and close and
the temperature changes quickly:
• Device Id = 50
• Address: 1083
• Value: increase of 60 seconds in the next attempts.
It is the correction time after which the valve corrects
the position, ex. if 360 means that every 6 minutes the
probe detects the supply water value, it is compared
with the set and it corrects the valve opening degree.
Although there is no sudden changes, the valve can not
maintein the correct temperature, or slowly it moves away
from the setpoint.
• Device Id = 50
• Address: 1085
• Value: decrease from 100 to 100 to a minimum of 200
(tha starting value usually is 400 or 1000). Next to
1000 the valve at each correction action open/close
less).
Attention,
An instability factor of the valve and of the temperature is
certainly set up by the compressor on/off and by the
consequent variation of the input temperature to the module.
Sometimes it can be necessary a thermal flywheel to give
more stability to the temperature, for ex. in systems with a
circuit of reduced dimensions between the mixing module and
the heat pump.
