Schematic Of The T° Sensors Positioning In The Hrg Units; Power Supply To The Fans And The Control Devices; Power Supply For The Electrical Antifreeze Protection Coil Kwin (Option) - Auerhaan HRglobal TAC5 Installations- Und Wartungsanleitung

3.1.2 Schematic of the T° sensors positioning in the HRg unit
To allow easier identification of the temperature sensors 4 different wire colors are used:
- T1 : black wire
- T2 : white wire
- T3 : blue wire
- T4 & T5 : green wire

3.2 Power supply to the fans and the control devices

All the internal cables (fans, controls, sensors, ...) to the main switch are factory pre-wired. All the power supply
wiring that remains is the main power supply to the main switch(es).
