This menu is used to make settings of an interlock control function in units of zones or
groups.
The simple interlock control is a function to automatically control groups or zones
corresponding to a change of the operation states or the stop states in any groups.
The settings of the simple interlock control are described below.
• The simple interlock can store a maximum number of 128 program registrations.
For each program, the following settings can be made :
•
Interlock input point
The target groups you want to monitor as the interlock input points
(e.g. air conditioning unit, Di unit*, Dio unit*, HRV) are registered.
* Monitoring is performed for the input states at the operation / stop connection point.
In one program, the maximum number of 128 groups can be registered.

•
Select condition of interlock input points
The interlock control function is initiated when the groups specified as the interlock
input points indicate the operation states described below. Select from (1)-(5) to
specify the condition. (The control function is actually initiated when the state of the
input point has changed.)
(1) No detection : Detection of inputs is not performed. (The control function is not
effective.)
(2) Any one or more of the groups ON :
When any one or more of the groups registered as the input
points turn on, the control function is initiated.
(3) All ON : When all of the registered groups as the input points turn on, the
control function is initiated.
(4) Any one or more of the groups OFF :
When any one or more of the groups registered as the input
points turn off to stop, the control function is initiated.
(5) All OFF : When all of the registered groups as the input points turn off to
stop, the control function is initiated.
*1 Selecting "Any one or more of the groups ON (or OFF)" while some interlock
input points are already ON (or OFF) will not initiate anew the interlock control
function even when another interlock input point turns ON (or OFF). (Once the
selected condition has become invalid and then, when the selected condition is
satisfied again, the function can be initiated.)
*2 When a communication error occurs in any of the interlock input points, the
condition will be checked only for the interlock input points in the normal
communication state.
•
Registration of control targets
A single group or zone, which is to be controlled when the interlock condition is met,
is registered.
* If the interlock condition has been met during a communication error in the control
target, the interlock control function will not be initiated even when the communication
error is cleared.
•
Settings of control details
Details of the control operations for the target device where the interlock condition
is met are defined. The available control operations are described below. Multiple
operations can be set at a time. (Ex. : Start Command and Change Temperature
Setting)
• Start / Stop commands
• Operation mode switching
• Change temperature setting
• Setting of permission / prohibition of hand-held remote controller operations
(Start / Stop, Temperature setting, Operation mode switching)
• Ventilation mode switching (*)
• Ventilation amount switching (*)
* for HRV
For one interlock program, two interlock outputs at the maximum can be specified.
