Several parameters of the MODU
CONTROL board have to be set, ba-
sed on the type of system the unit is
installed.
These changes of parameters are
summarised in the table below to
permit the installer to make the appro-
priate selections of the unit’s electro-
nic circuit board.
13.1. HOW TO MODIFY A USER
MENU PARAMETER
To access the
USER
setting press the
key and confi rm the password 000
pressing the key .
The display will show the parameters
of the
USER
index as three identifying
characters; the index remains displayed
for a second and then is replaced by the
value of the parameter it relates to.
To move to the following parameter
use the arrow keys . To modify a
parameter press the key , modify
the value using the arrow keys and
confi rm the modifi cation pressing the
key . To exit the menu press the key
13.2. HOW TO MODIFY AN

QUESTION
ANSWER
WHAT TO DO
(1) What type
of terminals are
installed in the
heating circuit?
• The unit is a coo-
ling only model
• Go to question 2
• Radiant panels
• Enter in parameter
StC
(index 3 menu USER) with the value of 35 °C
• Fan coil units or
low temperature
radiators
• Enter in parameter
StC
(index 3 menu USER) with the value of 45 °C (default
value)
• Other applications • Enter in parameter
StC
(index 3 menu USER) with the value of 55 °C
(2) Is the remote
control accessory
panel installed
(PR3)?
• Not installed
• Go to question 3
• Installed
• Enter in parameter
PAN
(index 9 menu INSTALLER) with the appropriate value:
Value (1):
• Season selection controlled from the unit circuit board
• ON/OFF control from the PR3
Value (2):
• Season selection controlled from the PR3
• ON/OFF control from the unit circuit board
Value (3)
:
• Season
selection controlled from the PR3
• ON/OFF control from the PR3
(3) Is domestic
hot water produc-
tion present?
• Not present
• Go to question 5
• Present
• Enter in parameter
ASA
(menu INSTALLER) with the value (1)
(4) In the do-
mestic hot water
circuit is a three
way diverting
valve present?
• Not present
• Go to question 5
• Present
• Enter in parameter
AAS
(index C menu INSTALLER) with the appropriate value
(in seconds): this parameter shows the reversing time for the three way diverting
valve in the circuit for the production of domestic hot water
(5) Is an ambient
thermostat pre-
sent?
• Not present
• No function
• Present
• This parameter enables a digital contact
ID
(shown on the electrical schematic
with the reference
TRA
) onto whWich to connect an ambient thermostat with
which to disable the compressors and electric heaters. Enter in parameter
trA
(index D menu INSTALLER)
, with the appropriate value selecting from:
1. Value (1 or 2): ENABLED
2. Value (0 or 3): DISABLED
3. It is reminded that the OPEN state of the contact represents
:
• stops compressors and heaters if the parameter value is set to 1
• stops compressors, pump and heaters if the parameter value is set to 2
• pump alarm (as in the previous software version), if the parameter value is set to 3
