Pressure sensors (B3 and B4)
One for each cooling circuit and connected to the coil col-
lectors. Provide information to the system for fan speed
adjustment in the summer and winter cycles, management
of defrosts in the heat pumps, prevent and lockout functions
of the system by excessively high pressure.
NTC probes (B5 and B6)
B5- For the detection and control of water intake temperature
(cool only and heat pump units).
B6- For the detection of water outlet temperature. Provides
information for antifreeze protection and control of the an-
tifreeze and backup heaters. If required, allows controlling
water temperature at the heat exchanger discharge.
Start-up
About 45 seconds after powering the unit, the start-up display
is activated. Default language: English.
1st display. Start-up (information on water temperature/unit
status)
- Water intake temperature.
- Water outlet temperature.
- Unit status (On/Off).
Press "down" to access the second display.
2nd display. Selection of status and operating mode
Selection of the On/Off mode (with "Enter", "Up" and
"Down")
On the heat pump units, select the Cool/Heat function (with
"Enter", "Up" and "Down").
To return to the 1st display, press "Esc".
System configuration (for authorized servicing personnel
only)
3rd display. Insert the password
The 3rd display, "Insert password" is accessed by pressing
"Up" from the 1st display (Start-up), or "Down" from the 2nd
display (selection of operating status/mode)
- From "Insert password" display, press "Enter".
- Enter the Password with the "Up" key.
- Press "Enter" to access the 4th "Menu" display.
4th display. Menu
From this display we can access a set of submenus that pro-
vide information on the unit or allow configuring the operating
parameters of same. Said submenus are as follows:
-/- Probes (Probes config.)
-A- Antifreeze
-B- Input/output
-c- Compressors (Comps. conf.)
-d- Defrost
-F- Condensation (fans)
-H- Unit configuration
-P- Alarm settings
-r- Temperature control (control param.)
-Fr- Software version/language selection
-t- Time configuration (not available)
To enter a submenu, select same with the "Up" or "Down"
keys, and then activate it with the "Enter" key.
Once the parameters are set with the "Enter", "Up" and
"Down" keys, press "Prg" to confirm the modification and
return to the "Menu" display. To exit the "Menu" display, press
the "Esc" key.
