10 TEMPERATURE AND HUMIDITY MEASUREMENT

10.1 Return air T+H probe

This probe is available for all the units that require humidity control and allows the enabling of the following functions:
•
dehumidification;
•
Humidification.
It also allows the reading of the humidity, in addition to temperature, and can be used for the calculation of the return temperature.
The probe is connected via Modbus to the Fieldbus port defined using the controller parameters at address 128.

10.2 Delivery air T+H probe

This probe is available for all the units.
It allows the reading of the humidity, in addition to temperature, and can be used for the calculation of the delivery temperature.
The probe is connected via Modbus to the Fieldbus 2 port of the pCO5+ with the address 134.

10.3 Remote T+H probes

These probes are available for all the units and the remote T+H probe 1 allows to enable the following function:
•
Return setpoint compensation.
It also allows the reading of the remote temperatures and humidities and can be used for the calculation of both the return and
the delivery temperature.
Probe 1 is connected via Modbus to the Fieldbus port defined using the parameter of the controller at address 129.
Probe 2 is connected via Modbus to the Fieldbus port defined using the parameter of the controller at address 130.
Probe 3 is connected via Modbus to the Fieldbus port defined using the parameter of the controller at address 131.
Probe 4 is connected via Modbus to the Fieldbus port defined using the parameter of the controller at address 132.
