6. Indication of operation standby:
This icon indicates that the unit is precooling/preheating. The
unit's start-up is delayed until precooling/preheating is finished.
Precooling/preheating means that the heat reclaim ventilation
units are NOT started while linked air conditioners are starting
up, for example, before office hours.
During this period, the cooling or heating load is reduced to
bring the room temperature to the set temperature in a short
time.
7. Indication of centralized control:
When a remote controller for air conditioners or devices for
centralized control are connected to the heat reclaim ventilation
units, this indication may be displayed.
While this indication is displayed, you may NOT be able to turn
the heat reclaim ventilation units on or off, or use the timer
function with the controller of the heat reclaim ventilation unit.

Initial settings can be made for the functions of the HRV units
(pre-cool/pre-heat, ventilation air flow, ventilation mode and

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.
Example 1:
To switch on the pre-cool/pre-heat function, and turn on the HRV unit
60 minutes after the air conditioner is turned on.
• Set the mode No. to "17" for group control, or "27" for individual
control, the setting switch No. to "2" and the setting position No.
to "02"
• Set the mode No. to "17" for group control, or "27" for individual
control, the setting switch No. to "3" and the setting position No.
to "03"
Example 2:
To switch the ventilation air flow to ultra high setting. (The units are
set at the high air flow setting at the factory)
• Set the mode No. to "17" for group control, or "27" for individual
control, the setting switch No. to "4" and the setting position No.
to "02"
