ENGLISH

Water tank temperature sensor Connection

• Select the suitable pump by referring to the flow rate table with water

temperature difference between the entrance and the exit.

• It is recommended that the flow rate is Rated water flow (refer to the

specification of PDB)

• Select a correctly sized pump capable of delivering required flow rate at the

static head pressure of the system piping and 

Hydro Kit

.

• Select a suitable relay for pump capacity when connecting the pump to the

unit.

• Connect the relay to terminals 11 and 12 located in the 

Hydro Kit

control

box.

• Connect the domestic hot water tank sensor to PCBʻCN-TH4ʼ socket

(red).
