9 Control System
9-3 Applicable patterns
9-3-2 To connect the remote control to the HRV unit
(Part 1) single-group interlocked operation
Purposes and functions
When the HRV unit is interlocked to the single-group
control system, the remote control for HRV unit will be
connected to change the setting mode at the HRV unit side.
Cautions
1. It is not possible to set the "On / Off" and "timer" setting
by the remote control for HRV unit. Also it is not
possible to display the filter-sign and malfunction code
neither on the remote control for indoor unit nor on the
remote control for HRV unit.
2. Since this is two remote control system (for Indoor unit
and HR unit), the Master / Slave setting is required.

(Part 2) Centralized control operation
Purposes and functions
• Beside the operation by central remote control, the
remote control for HRV unit can change the ventilation
mode setting, the ventilation air flow setting and etc.
Cautions
1. In case of Zone control, the operation / stop and the
timer setting cannot be done by the remote control for
the HRV unit. (The operation lamp blinks twice to
indicate that the operation is not possible.)
2. The remote control for the HRV unit cannot set the
group no. for centralized control. In this case, the remote
control for the indoor unit has to be connected once for
this setting.
3. It is not possible to have Precool / preheat time setting
function.
