type description PRO CONTRAControl type X By DDC controller : 0-10 V control

ΔT = Tset

- Tmeasured

Tmeasured

= Td, Ts or Tr

- possibility for Td control- flexibility in applications

- higher cost (DDC is needed)

Control type Y Fixed TeTe = user setting : 3 ~8 °C

- Low cost- no BRC needed no air temp control

Control type Z using BR1CD + KRP4(remote on/off)

Low cost - BRC/KRP4 needed- no possibility for Td control

Customer 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 :

1. Same small temperature gradient and control possibilities2. No hydraulic components 3. Better price setting
