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.
