Loading registers…
Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show supply, extract and outdoor temperature on a ModbusCloud dashboard to check heat recovery across the seasons.
- Send an email alert when filter impurity rises above a threshold, so the filters are changed on time.
- Get an alert as soon as the active alarm count is not equal to 0 and see the alarm code in the history.
- Switch a unit to Economy mode or change its temperature setpoint remotely from the portal.
- Track supply and exhaust fan power and energy counters over 365 days to compare units in a fleet.
Installation
Connect the RS485 port of the ModbusCloud Gateway to terminals 1 (B), 2 (A) and 3 (GND) of the C5 board, with a termination resistor at the end of the bus.
Check the Modbus address and serial settings in the web interface or on the control panel: default address 1, 19200 baud, 8E1.
For Modbus TCP, connect the RJ45 port of the C5 to the network of the Gateway and use the IP address of the controller, default 192.168.0.50, port 502.
In ModbusCloud, add a Modbus device with these settings and import this template.
Check that Supply Air Temperature and AHU Run Status match the control panel.
Things to watch for
The C5 does not answer on RS485. What should I check?
The default is 19200 baud, 8 data bits, even parity and 1 stop bit, address 1. Many tools default to no parity. Check that B is on terminal 1 and A on terminal 2, swap them if nothing answers, and connect GND when the cable is longer than 10 m.
Why does a temperature show 229 instead of 22.9 °C?
The controller sends temperatures in tenths of a degree. The main temperatures in this template already use a factor of 0.1. The temperatures of the additional zone modules have no stated scale, so they are shown as raw values; divide them by ten if they match the other temperatures on your unit.
Which unit do the airflow values use?
Airflows follow the Flow Units register: m3/h, l/s, m3/s or Pa. Read Flow Units first and set the unit of the airflow registers to match in your dashboard. In m3/s the value is sent in thousandths, so 3500 means 3.5 m3/s.
What should I watch out for when writing registers?
Several registers start an action when you write 0x99C5 (39365): resetting alarms, calibrating clean filters, resetting counters or user settings. Write them only on purpose. Flow setpoints are corrected to the allowed range, so read the value back after writing.
