value
CH1
Circulating fluid temperature It indicates the current temperature.

Circulating fluid set temperature It indicates the set temperature.

Circulating fluid discharge pressure It indicates the discharge pressure.

Circulating fluid
flow rate
It indicates the fluid flow rate. This value is not measured by a flow meter. It should be used as a
reference value (rough indication). It includes the flow rate in the bypass circuit.

CH2
Circulating fluid temperature It indicates the current temperature.

Circulating fluid set temperature It indicates the set temperature.

Circulating fluid discharge pressure It indicates the discharge pressure.

Circulating fluid
flow rate
It indicates the flow rate measured by a flow meter.
It does not include the flow rate in the bypass circuit.

Circulating fluid electric conductivity It indicates the electric conductivity.
