Schematic Of The T° Sensors Positioning In The Hrup Units; Power Supply To The Fans And The Control Devices; Power Supply For The Electrical Antifreeze Protection Coil Kwin (Option); Power Supply And Connections For The Electrical Post Heating Coil Kwout (Option) - P.LEMMENS HRup 450 TAC5 Manuel D'installation Et De Maintenance

3.1.2 Schematic of the T° sensors positioning in the HRup 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.
Wiring specifications:
Unit type Supply Voltage
HRup 450
HRup 800
HRup 1200
HRup 2000
