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.

HRV unit
(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.
