Superheat Controller| Doc V2.1 |HVAC Software ... - Microstaq

The status of the following parameters is displayed:
Parameter Description
Supply Voltage The USHS auto detects the supply voltage
and is shown. The voltages that can be
detected are 12VDC, 24VDC and 24VAC.
Refrigerant The refrigerant selected in the setting tab
is also shown.
Measured Pressure
(Gauge)
Measured
Temperature
The measured pressure at the exit of the
evaporator where the USHS is located.
Measures external temperature at the
evaporator exit.
Calculated Superheat Real-time calculated superheat value
Alarm Lists any fault condition in the system (for
example: High Input Voltage). It will be
blank if there are no faults detected.
Unit Information The unit information is displayed at the
top of the screen. It consists of
Manufacturer ID, Unit Version and
Firmware version.
RECORD STATUS DATA
To begin logging system data from the USHS, complete the
following steps:
1. From the Status Refresh Frequency in Sec drop-down
list, select the required status refresh frequency. The
USHS displays and records data as selected refresh
frequency. The impact of this selection impacts three
things
i. Status screen refresh
ii. Frequency of the data recorded
iii. Frequency of the data points shown on the
run-time generated plot.
2. Click Record Status Data button to save the Status
details to a file.
3. Select a File path to select the location of the file
4. Enter the File name
5. Click Open to begin logging data.

6. The logged data will be saved in text format. The data is
always recorded in US units only.
The units selected on the status screen do not
impact the data collection units.
The data file displays the USHS unit information, auto detected
voltage, refrigerant setting, run-time data, time and all the items on
the status screen at intervals based on the selected Status Refresh
Frequency.
Data recording will not occur while a message
box is open.
If the Refrigerant Setting tab is selected while
data is recording, a message box will appear
prompting the user to stop recording data.
Click OK. Then click the Recording Data button to stop recording data.
The Refrigerant Setting will now be accessible.
The Refrigerant Setting may now be changed. To resume recording
data, click Record Status Data.
A new file must be created for the newly selected
refrigerant. If an existing file is selected, the USHS
Interface will check the refrigerant setting in that file
to ensure that the selected refrigerant matches.
If the refrigerant settings do not match, a Check
Refrigerant message box will appear.
