Product Usage Instructions

The Composite Temperature + Humidity Controller comes with various utility parameters, temperature parameters, relative humidity (% RH) parameters, OP3 function parameters, supervisory parameters, and compressor operation & power indication parameters. The users can refer to the respective pages in the manual for detailed information on these parameters.

To use the device, follow the below steps:

1. Connect the RTD Pt100, 3-wire for temperature measurement and DC Linear (Voltage) for humidity measurement to the device as per the wiring connections mentioned in the manual.
2. Configure the utility parameters using the PAGE-33 section of the manual. The users can set the compressor control strategy, zero offset for temperature value, and range for low and high temperature values.
3. Configure the temperature parameters using the PAGE-10 section of the manual. The users can set alarm-1 band, alarm-1 hysteresis, proportional band, integral time, derivative time, and cycle time.
4. Configure the relative humidity (% RH) parameters using the PAGE-11 section of the manual. The users can set alarm-2 band, alarm-2 hysteresis, proportional band, integral time, derivative time, and cycle time.
5. Configure the OP3 function parameters using the PAGE-13 section of the manual. The users can set output-3 function selection, compressor setpoint, compressor hysteresis, and compressor time delay.
6. Configure the supervisory parameters using the PAGE-12 section of the manual. The users can enable/disable SP adjustment on PAGE-0, self-tune command, and baud rate.
7. Configure the compressor operation & power indication parameters using the PAGE-1 section of the manual. The users can set compressor operation mode, output power for temperature loop, and output power for %RH loop.

Note: The users can refer to TABLE-1 in the manual for RH input configuration. The device is calibrated for 0 to 5 VDC input for % RH. However, the transmitter output signal may be any voltage between 0 to 5 VDC. The users can use the formulae mentioned in TABLE-1 to compute the range low and range high values for RH input configuration.

TABLE-1 RH INPUT CONFIGURATION

The controller is calibrated for 0 to 5 VDC input for % RH. The transmitter output signal, however, may be any voltage between 0 to 5 VDC (For e.g. 0 to 1 VDC,1 to 3.6 VDC, 0 to 3.3 VDC etc.). The value for ‘Range Low’ and ‘Range High’ parameters must be corresponding to 0 and 5 VDC only. For this, use the following formulae for computing the ‘Range Low’ and ‘Range High’ values.
