VRF Simple Wired Remote User Guide
2 1 User Guide Variable Refrigerant Flow (VRF) System Simple Wired Remote Control Model Number: TVCTRLTWR001T, TVCTRLTWR001A Important: Environmental Concerns! Scientific research has shown that certain man-made chemicals can affect the earth's naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs. Important: Responsible Refrigerant Practices! Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them. Wired Remote Control Display Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment. Indicates a potentially hazardous situation which, if not avoided, WARNING could result in death or serious injury. Figure 1.

Before installing/servicing this unit, technicians MUST put on all Personal Protective Equipment (PPE) recommended for the work being undertaken. ALWAYS refer to appropriate MSDS sheets and OSHA guidelines for proper PPE. When working with or around hazardous chemicals, ALWAYS refer to the appropriate MSDS sheets and OSHA guidelines for information on allowable personal exposure levels, proper respiratory protection and handling recommendations. If there is a risk of arc or flash, technicians MUST put on all necessary Personal Protective Equipment (PPE) in accordance with NFPA70E for arc/flash protection PRIOR to servicing the unit. Failure to follow recommendations could result in death or serious injury.

Mode Description Auto In Auto mode, the indoor unit automatically sets the temperature and fan speed to maintain the selected temperature. If the indoor temperature is too high, a cooling breeze is generated until the room returns to a comfortable level. As the room cools, the fan slows down and maintains a gentle airflow. Cool In Cool mode, the temperature setpoint, fan speed, and air flow direction on the indoor unit can be controlled. Dry In Dry mode, the unit dehumidifies the indoor air. Fan In Fan mode, the unit ventilates the area to maintain a comfortable indoor environment. Heat In Heat mode, the temperature setpoint, fan speed, and air flow direction on the indoor unit can be controlled. Notes: • There may be a delay before the fan begins running to avoid generating a cold breeze. • The defrost indicator (Defrost) appears when frost is being removed from the outdoor unit. When the defrost function is completed, the defrost indicator disappears. • After heating operation is stopped, the fan continues running for a period of time to cool the unit.
