System Design ApplicationsIntroduction
• Installing DHW temperature sensor
Length of DHW temperature sensor: 10 m (Provided as default)
Connect DHW temperature sensor to PCB CN-TH4 and insert sensor in the temperature sensor pocket
in tank.
DHW Tank Kit must be used for communication between DHW tank and indoor unit.
It’s for communication with the DHW tank which has electric heater.
• Installing tank KIT
Follow bellow procedures Step 1 ~ Step 6
Step 1. Find magnetic switch and ELB(MCCB) in the kit. Fit them into the indoor unit control box with a
braclet and screws.(symbol Ⓐ at picture)
Step 2. ‘CN_B/HEAT(A)’(white connector)of the indoor unit PCB with magnetic switch contact using en
-
closed cable(symbol Ⓑ at the picture). Connect magnetic switch contactor port no. A1 and A2.
Step 3. Connect magnetic switch contactor port no.L1 and L3 with ELB(MCCB) port no. 2 and
4(symbol Ⓒ at the picture).
Step 4. Connect magnetic switch contactor port no. T1 and T3 with terminal block 1 port 6 and 7(sym

Step 5. Connect ELB(MCCB) to Terminal Block.
1Ø Electric Heater Model → Connect ELB(MCCB) port no.1 and 3 with terminal block 3 port 3 and
4(symbol Ⓔ at the picture).
3Ø Electric Heater Model → Connect ELB(MCCB) port no.1 and 3 with terminal block 3 port 1 and
2(symbol Ⓔ at the picture).
