Centralized control system
"All" control
When using Adapter PCB for remote control (KRP2A51) or schedule
timer (DST301B61)
A maximum of 64 air conditioners and HRV units can be
connected to the F1 and F2 terminals.
This system does not require group number setting for
centralized control. (auto-address system)
The Adapter PCB for remote control and schedule timer cannot
be used together.
The Adapter PCB for remote control can be mounted on the
electric component mounting base of either the HRV unit or air
conditioner. (The HRV unit can accept only the KRP2A51)
For raising the remote-controlled ventilation air flow rate from
"High" to "Ultra-High", connect the remote controller for the air-
conditioner to HRV and make settings on site.
(Refer to "Initial setting" under item
"List of Settings" on
page 13
.)
"All"/"individual" control
When using the on/off controller (DCS301B61)
A maximum of 64 air conditioners and HRV units can be
connected to the F1 and F2 terminals.
This system allows connection of four on/off controllers.
It is necessary to assign a central control group number to each
HRV unit and air conditioner.
Regarding the setting of the group number, refer to the section
on "the centralized control group number setting" in the
operating instructions of the On/off controller.
Use the remote controller of the air conditioner to make the initial
settings.
Example:
Follow the procedure below to set the centralized group No. 2-05 to
HRV 1.
Procedure
Set the central control group number using the local setting on the
remote controller.
Mode No.: "00"
Central control group No.: "2-05"
The setting is now complete.
For the ventilation air flow setting, follow the procedure described in
the section
""All" control" on page 18
