The template shows zero or no data for indoor temperature. What should I check?

Confirm that the MBS-1 gateway has established communication with the AC indoor unit. The status LED on the Intesis device should indicate a valid connection. If the AC unit is off, some models may not report temperature until powered on.

Can I use this template for any AC brand?

This template works with all Intesis MBS-1 gateways, but the AC brand must be supported by the specific MBS-1 model you purchased. Check the Intesis compatibility list at intesis.com before ordering.

Vane control registers do not seem to have any effect. Is this normal?

Not all AC brands or indoor unit models support motorized vane control via the Intesis gateway. Check the Intesis documentation for your specific MBS-1 model to see which registers are active for your AC brand.

What baud rate and parity settings should I use?

The default is 9600 baud, 8 data bits, no parity, 1 stop bit. These settings must match on both the MBS-1 gateway and the ModbusCloud gateway RS-485 port.
