2 PIPE SYSTEM WITH ELECTRICAL HEATING AND SPECIAL TERMINAL BOX WITH RELAYS AND FUSE 1 Heater Element and 1 Temp Cutout upto size 12 2. Heater Element and 2 Temp Cutout for size 14 Three Speed Switch 2 Pipe System Two Port & Three Port Water Valves for Cooling 4 Pipe System Hot Water Heating Unit motor is a single-phase, permanent split capacitor type with three speeds tappings / /, wired to the terminal block with colour coded wires. Cooling is controlled by either modulating of switching On and Off the chilled water supply by means of an electrically operated valve. (Refer Fig.1 & 2) 3+1 (A) and 4+1(C) configurations can be used for hot water heating. A separate hot water valve is required to be installed on the 1 row eating coil. Mode of switching from cooling to heating can be automatic or manual 2 Pipe System with Electric Heating Special Terminal Box YDFC can be provided with one stage electrical heater of following capacities: Size 08 to 12-1500 Watts Size 14-2000 Watts Size 16 to 20-3000 Watts These heaters are provided as an option at extra cost. It is important that electrical heaters are interlocked to ensure that the heating elements receive no power supply when the fan is not selected to operate. Heater are provided with high temperature cut out at standard and are terminated in a terminal box for field wiring (Refer. Fig.3) The electric heater input power based on the condition: -speed&0pa, accuracy: ±10% A special terminal box equipped with relays and fuse can eb provided at extra cost. This allows the power for the electrical heaters to be supplied separately. Technical Sales Guide # 040 YDFC 0714 Page 18
