13. PROCEDURE FOR SELECTION OF SYSTEM TYPE

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.
QUESTION ANSWER
(1) What type
• The unit is a coo-
of terminals are
ling only model
installed in the
• Radiant panels
heating circuit?
• Fan coil units or
low temperature
radiators
• Other applications • Enter in parameter StC (index 3 menu USER) with the value of 55 °C
(2) Is the remote
• Not installed
control accessory
• Installed
panel installed
(PR3)?
(3) Is domestic
• Not present
hot water produc-
• Present
tion present?
(4) In the do-
• Not present
mestic hot water
• Present
circuit is a three
way diverting
valve present?
(5) Is an ambient
• Not present
thermostat pre-
• Present
sent?
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
the value using the arrow keys and
confi rm the modifi cation pressing the
key . To exit the menu press the key
WHAT TO DO
• Go to question 2
• Enter in parameter StC (index 3 menu USER) with the value of 35 °C
• Enter in parameter StC (index 3 menu USER) with the value of 45 °C (default
value)
• Go to question 3
• 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
• Go to question 5
• Enter in parameter ASA (menu INSTALLER) with the value (1)
• Go to question 5
• 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
• No function
• 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
