Operating the HRV unit using the remote controller of the
VRV-system air conditioner
Please read the manual supplied with the remote controller for more
detailed instructions (optional controllers: BRC1D52 or BRC1E52).
BRC1D52: Remote controller for VRV
When the VRV-system air conditioner is connected with the HRV unit
with a direct duct, the remote controller of the air conditioner cannot
be used to select the VENTILATION mode. To use the HRV unit
without operating the air conditioner, set the air conditioner in the
FAN VENTILATION mode and select the low fan speed.

When connecting to Remote controller for HRV
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 "List of Settings" on page 13.)
Set the switch on the printed circuit board to the factory setting.
Wiring and connections in combination
with “VRV-SYSTEM”
Standard 1-group linked-control system
The remote control of the air conditioner can be used to control
up to 16 air conditioner indoor units and HRV units.
Initial settings can be made for the functions of the HRV units
(pre-cool/pre-heat, ventilation air flow, ventilation mode and
“Fresh-Up”).
Use the remote controller of the air conditioner to make the initial
settings for the HRV units.
Refer to “Initial setting” under Item "List of Settings" on page 13
Pre-cool/pre-heat function
When the pre-cool/pre-heat function is set, the HRV unit switches on
at the preset time (30, 45 or 60 minutes) after the VRV-system air
conditioner begins cooling or heating operation. The function is set
OFF at the factory. Therefore, to use this function, the initial setting
must be made using the remote controller of the air conditioner.
If the air conditioner is re-started within two hours after the operation
was stopped, this function does not operate.
