POWER CABLE WIRING DIAGRAM Demand Control Signal Receiver (DCSR) Installer’s Manual The Tmac DCSR POWER CABLE supplies mains power to the Tmac DCSR. The POWER CABLE should be connected to the incoming mains supply for the air conditioner. Generally iit is piggy-backed into the mains supply terminals as shown below. BEFORE YOU START Read and understand this guide before operating this equipment. This guide must be kept for future reference with the product supplied. The T-Mac® Demand Control Signal Receiver is only to be installed by a ‘qualified person’ and must be used in conjunction with the user’s own working and safety procedures, without compromising the integrity of the Thew & McCann product supplied. Follow all safety instructions contained within this guide. QUALIFIE D PE RS ON A qualified person is one who is familiar with the installation, construction, operation or maintenance of the equipment and the hazards involved. In addition this person is competent, trained and authorized to undertake the work involved in accordance with established safety and working procedures DESCRIPTION The DCSR receives AFLC (Audio Frequency Load Control) signals via the mains input from the electricity supplier (the same signal used to switch off-peak hot water systems) and allows the electricity distributor to control network peak demand by instructing the connected air conditioner to cap it’s electrical load.

THE LIMIT OF THE SELLERS LIABILITY IS DETAILED UNDER ITEM 12 OF THEW & McCANN’S “STANDARD TERMS OF TRADE” • • • • • • • • The Demand Control Signal Receiver (DCSR) is designed to be installed by a ‘qualified person’ i.e. an electrician, within, or adjacent to an existing air conditioning unit indoors or outdoors. The qualified person connects the DCSR’s “POWER CABLE” in parallel with the air conditioner’s mains supply. The DCSR’s “CONTROL CABLE” is then installed and connected between the DCSR and the air conditioner’s dedicated demand management (DRM) connector. The DRM connector may be an RJ45 socket, or a set of screw terminals depending on the air conditioner model. For units fitted with screw terminals, an RJ45 to screw terminal adapter should be used. This appliance is intended to be installed in accordance with the wiring rules (AS/NZS 3000). The product is intended to be connected to the fixed wiring, and installed in a location where it is not likely to be subjected to mechanical damage. This product should be MOUNTED VERTICALLY WITH THE CABLE ENTRY FACING DOWN to prevent water ingress via the cable entry over a long period. The DCSR can be cable tied to existing supported wiring or screwed to a flat surface, it can also be mounted inside the air conditioning unit safely, near the control connections. The DCSR can be positioned behind existing air conditioning duct work, or in a wall cavity. A means for disconnection shall be incorporated in the fixed wiring according to the wiring rules. The Tmac DCSR is intended to be powered from a 240V domestic power circuit via the POWER CABLE (see the POWER CABLE wiring diagram). The internal components within the DCSR are factory set and should never be accessed. The wiring diagrams in this manual should be read and understood in conjunction with the air conditioner manufactures own documentation. WIRING OVERVIEW CONTROL CABLE WIRING DIAGRAM The Tmac DCSR has two cables to connect, a POWER cable and a CONTROL CABLE. The power cable is used to supply mains power to the DCSR, while the control cable is connected to a special dedicated demand managment (DRM) connector on the air conditioner. Consult the installers manual for the air conditioner to find the location of the DRM connector. It will either be located in the head unit (OPTION A) or the compressor unit (OPTION B). The Tmac DCSR CONTROL CABLE is connected to the dedicated DRM connector on the air conditioner. The connector will either be an RJ45 connector (OPTION X), or a set of screw terminals (OPTION Y). Note: THE DRM CONNECTOR IS ALWAYS SEPARATE FROM THE INTERCONNECT TERMINALS.
