Pair application: ERX + EV + control box + AHU
1. Concept
ERX are R410A inverter units for use with AHU in pair applications
ERX is always used in combination with expansion valve kit (EV kit) and a control box
ERX can not be used with standard Sky Air indoors

P: Pair : Combination depending on AHU coil volume (details will be clarified in TW drawings)
n: Qty determined by connection ration or maximum number of indoor units.
(in combination with VRV-outdoor, the EKEXV -kit is considered as
one of the indoor units)

5. Control possibilities
3 control systems can be selected :
X: Control of air Temperature (Td, Ts, Tr) with external controller (DDC)  PAIR
Y: Control of evaporating Temperature (Te) with Daikin controller  PAIR
Z: Control of air temperature (Ts, Tr) with Daikin controller  PAIR & MULTI

6. Benefits
Customer benefits
1. Inverter outdoors (ERX or VRV)
2. Pair (ERX) and multi applications (VRV)
3. Extended control systems possible :
• control on evaporating temperature
• control on air temperature (suction / discharge / room temperature)
Compared to Chillers :
