When a parameter needs to be changed, the Select < and Select > buttons allow the value to be changed and Enter confirms the change. Press the Esc button to return after the change is made. First, activate the Modbus port on the AZL (no password required): 1. Operation > OptgModeSelect > Type of Gateway = Modbus 2. Operation > OptgModeSelect > GatewayBASon Note: Older AZL units may read 'GatewayDDCon' instead. 3. The AZL should now read 'Gateway Mode active'. Next, set up the required parameters through the AZL (no password required): 1. Params & Display > Access w‐out PW > AZL > Modbus > Address = 1 2. Params & Display > Access w‐out PW > AZL > Modbus > Baudrate = 19200 bit/s 3. Params & Display > Access w‐out PW > AZL > Modbus > Parity = no 4.

- Page 16 0: Automatic 1: Burner on 2: Burner off Note 5 – Set local/remote (AV29) to 1 for remote. Once in remote the desired mode can be set using AV31 (0 = local/automatic, 1 = burner on, 2 = burner off). If AV31 is set to automatic, write the desired setpoint using AV32. If AV31 is set to burner on, write the desired firing rate using AV33. The firing rate must be between 0% and 100% to remain valid. AV29 must be actively written at least once during the timeout period to reset the timeout counter. Once the timeout counter reaches the timeout value local/remote will revert to local (failsafe operation). Note 6 – Counter values can only be reset to zero. Note 7 – There are 9 lockouts in memory (current plus 8 history). There are 21 errors in memory (current plus 20 history). The addresses for the historical data are all in the same format as shown in the mapping. Use the formula to find the correct instance. For example, the analog input instance for the ERROR CODE history index 4 would be (10 x 4) + 280 = 320, or AI320. The analog input instance for the LOCKOUT OUTPUT history index 7 would be (20 x 7) + 104 = 244, or AI244. Information in this publication is based on current specifications.
