Wiring and connections in combination with Indication of operation standby: "VRV-SYSTEM" 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 Standard 1-group linked-control system units are NOT started while linked air conditioners are starting The remote control of the air conditioner can be used to control up, for example, before office hours.

The Adapter PCB for remote control and schedule timer cannot Example: be used together. Follow the procedure below to set the centralized group No. 2-05 to The Adapter PCB for remote control can be mounted on the HRV 1. electric component mounting base of either the HRV unit or air Procedure conditioner.
Zone 2 Fresh-up operation The HRV units operate in the zone-linked mode, as described in the section, "Linked control with more than two groups" on page 16. For Purposes the initial setting, follow the procedure described in that section. When combined with a local ventilating fan (such as the one in toilet It is necessary to assign a central control group number to each and kitchen), the air flow rate of HRV is balanced by either fan HRV unit and air conditioner.
