Pre-cool/pre-heat function
When the pre-cool/pre-heat function is set, the ERV unit will be
turned on at the preset time (30, 45 or 60 minutes) after the
VRV-system air conditioner begins cooling or heating opera-
tion. The function is set OFF at the factory.
Therefore, to use this function, the initial setting must be made
using the remote controller.
If the air conditioner is re-started within two hours after the
operation stopped, this function is disabled.

ERV unit 60 minutes after the air conditioner is turned on.
