S & P Sabik

Use cases

• Monitor supply and extract air temperatures on a live dashboard to verify heat recovery efficiency.
• Create an alert when a filter alarm triggers so the end user receives a timely maintenance notification.
• Remotely switch the working mode between away, normal, and boost to match building occupancy schedules.
• Log indoor humidity trends over time to identify ventilation capacity issues during high-occupancy periods.
• Activate manual bypass mode in summer to allow free cooling when outdoor temperatures drop at night.
• Track extract and supply motor RPM to detect early signs of fan degradation or belt wear.

Installation

1. 1Connect the Modbus RTU wiring (A, B, and GND) from the ModbusCloud gateway to the RS-485 terminal on the S&P Sabik unit.
2. 2Verify the Sabik's default communication settings: slave address 1, baudrate 19200, parity Even, and adjust your gateway port settings to match.
3. 3If multiple devices share the same RS-485 bus, change the Sabik slave address using the onboard menu or the template's communication output registers to avoid conflicts.
4. 4Import the S&P Sabik template in the ModbusCloud platform and assign it to the correct gateway and port.
5. 5Confirm that register address offset of minus 1 is accounted for in coil and register writes, as documented in the template.
6. 6Test a control action such as toggling Manual Boost to verify bidirectional communication is working correctly.

Things to watch for

01

I cannot communicate with the Sabik even though the wiring looks correct. What should I check?

The Sabik defaults to baudrate 19200 with Even parity. Many gateways default to 9600 or no parity. Ensure your gateway port is set to 19200 baud, 8 data bits, Even parity, and 1 stop bit.

02

Why does writing to the documented register address not work?

S&P documentation uses 1-based register numbering. The template accounts for a minus 1 offset, so coil 17 becomes address 16. Verify you are not applying the offset twice.

03

What unit do the control voltage registers use?

Control voltage values are expressed in decivolts (dV). For example, a value of 100 corresponds to 10.0 V. Scale your setpoints accordingly.

04

Can I use this template for all three Sabik models without changes?

Yes. The Sabik 210, 350, and 500 share the same Modbus register map, so one template works for all three models.
