8.8. PREHEATER AND COOLER
AmberAir Compact CXP units can be equipped with external electrical or water preheater. Automatic and manual protection devices must be
connected to MCB EX1 controller‘s X21 connector when electric preheater is equipped with these connection terminals. Otherwise, jumpers are
installed in the X21 connector protection inputs. Water preheater consists of circulation pump, valve actuator and temperature sensor. Only one
preheater can be connected at the time.
CXP units can also be equipped with external water cooler or DX cooler. Water coolers consists of circulation pump, valve actuator and tempera -
ture sensor. Control board has DX cooler inputs/outputs: valve actuator control, failure input, reverse output and power line. Only one cooler can
be connected at the time.
Preheater and cooler wiring diagrams can be found on section 8.9.
