For the technical integration of a domestic hot water storage tank into the FTC 6 and FTC 7 heat pump control unit.
Consists of 1 x temperature sensor, connection cable 5m.
THW5B is an optional part (PAC-TH011TK2-E (5 m)).
Connect the THW5B cable to the CNW5 connector on FTC (Master) if the DHW tank is available.
When the THW5 cable supplied with FTC (Master) is too long, bundle the excess cable outside the FTC (Master) unit.
Do not bind the wires in the FTC (Master) unit.
Place THW5B on the position where tank water temperature can be detected correctly.
It is recommended to position the thermistor at the mid height of the DHW tank (to control DHW heating with this sensor).
It is recommended to protect the thermistor with heat insulating materials so as not to be affected by ambient temperature.
Especially for double (insulated) tank, thermistor should be attached to the inner side (to detect the water temperature).
