CSNET Manager LT/XT
Unit configuration
The unit settings show all the data of each of the units controlled by CSNET Manager.
The information given is as follows:
• Indoor Unit
- Location: Name of the room conditioned by this unit.
- Area: Zone to which this unit belongs.
- IU Type: Model of indoor unit (recognized by the system) (see Note 1).
- IU Model: Exact model of the indoor unit (see Note 2).
- IU Serial No: Serial Number of the indoor unit (see Note 2).
- Sec.Address: in set free of H-LINK (I) with more than 16 indoor units, we use a virtual address to indicate that this
unit is a secondary unit of the previous unit.
- RCS Group: Remote control number used by more than one indoor unit including this one, for example 1. A second
group should have a different number, etc. If any of the parameters within a group changes, all the groups which
form it will adopt the specified value at the same time. This process is automatic and there is no need to select the
unit group to change (see Note 4).
- RCS Control: Sets the RCS control as master, slave or RCS not installed.
- CH Box: Number of the CH (Cool/Heat) distribution box used by more than one indoor unit including this one.
When the automatic cooling/heating operation has been chosen, a common number in this field has to be chosen
to ensure that all these units change their operating mode simultaneously.
If the operation mode of one of the units in this group is changed, CSNET Manager will also change the mode of
operation of the other units of the same group which no longer have a compatible operation mode (see Note 5).
- Timer Disabled: Deactivate the timer setting option.
• Outdoor Unit
- Type: Model of the outdoor unit connected to this indoor unit (recognized by the system) (see note 3).
- OU Model: Exact model of the outdoor unit connected to this indoor unit (see Note 2).
Is FX: If you mark the check box, this unit corresponds to a 3-tube unit (FXG or FXN).
-
