Buttons:
-
Welcome: To return to the home page
-
Times: To go to the schedule zone page (See schedule management paragraph)
-
Settings: To go to the chiller setting page
-
Log: To go to the log page. (A147 = Out temperature / A148 = Water input temperature / A149 = Water output temperature
-
Return: To go to the previous page
Drop Lists:
-
Start/Stop: Change here the chiller status (On/Off).
-
Auto: the chiller is managing its own On/Off
-
Off: Set the chiller to Off. Once the chiller is Off the drop list goes automatically to
“Auto” mode
-
On: Set the chiller to On. Once the chiller is On the drop list goes automatically to
“Auto” mode
-
Schedule: set the chiller start/stop according to schedule. /!\ if the schedule is in On mode the chiller will be forced in On
mode. Please remove this mode or the BMS connection before operating on the chiller.
Note: If the chiller is On the condenser fans on the HMI view will turn. If the chiller is off they will not move.
-
Changeover: Change the chiller mode (Heat/Cool)
-
Cool: Set the chiller in cooling mode
-
Heat: Set the chiller in heating mode
-
T
°out: The chiller will automatically set its own mode according the outside temperature.
-
T
°in: The HMI automatically sets the chiller mode according the indoor temperature average.
Indexes:
1)
Light: This light shows the chiller status. Green = On / Red = Off
2)
Light: This light shows the chiller mode. Blue = Cool / Red = Heat / Yellow = Dead zone
3)
Temperature: It shows the actual chiller set point
4)
Temperature: It shows the water input temperature
5)
Temperature: It shows the water output temperature
T
°in mode:
This mode uses all the space temperature measured by fan coils which are in occupied mode (On) and makes an average. If the
average is above the high limit (see chiller settings) the chiller will turn in cooling mode. If the average is below the low limit (see
chiller setting) the chiller will turn in heating mode. If the average is between the two limits the chiller will remain in the same mode
he was (it doesn't set the chiller in dead zone).
If all the fan coil are in uncopied mode (off) during night for example. The average be calculated using all the fan coil space
temperature and the HMI will use the protection settings (see chiller settings) to turn the chiller in heating or in cooling mode.
T
°out mode:
This mode uses the outside temperature measured by the chiller to turn the chiller in heating or cooling mode. If the outside
temperature is above the high limit (see chiller settings) the chiller will turn in cooling mode. If the outside temperature is below the
low limit (see chiller settings) the chiller will turn in heating mode.
