Product Info Literature Overview Microprocessor-based integrated primary burner control for automatically fired gas, oil or combination fuel single burner applications. Safe-start check looks for a flame signal at start-up, same as the old mechanical relays did, but now includes checking for a flame signal in honeywrll. On the E and L, all terminal functions are the same. This is prohibited in all electrical codes. Functions include automatic burner sequencing, flame supervision, system status indication, system or self diagnostics and troubleshooting.

Order Status and History. Programmers also check all the interlock circuits continuously during standby. It depends on how relay jumper JR3 is configured.

Can a RM be used with a standing pilot? It is active in standby. If a display is used, fault codes 67 or will appear. They consist of a specific resistor. Text in Help dialog, To be determined by the Business. Can I jumper terminal G to L2?

Five LEDs provide sequence information. Yes, but they are for export and would not be used in this country. The only difference is that the RM includes an SA display module and the RM has only a dust cover where a display can go. Long enough to result in four complete air changes through the burner. Honeywell does not recommend even trying to restore a clipped jumper. Testing Wireless Solutions Testing wireless transmitters link.

If the display is removed from an RM in standby, a lockout will occur. Microprocessor-based integrated primary burner control for automatically fired gas, oil or combination fuel single burner applications.

RMA Honeywell BURNER CONTROL

Turn off more accessible mode. When using an M, many times there will be no L.

Product has not been associated with this account, therefore your catalog will be empty. Also, on a call for heat, all the output terminals are momentarily turned into inputs for a load check. It depends on the length of the purge card timing. During the initiate period, all the Series of controls examine the voltage and frequency of the power supplied.

Subbase and amplifier are required for operation. Terminal 19 is used to configure terminal If using the two-second-purge card, the airflow switch must close in 2 seconds. If JR3 is clipped, the control will lockout if the air flow switch does not close in the allotted time.

You will have enhanced the safety of the system. This can be calculated. General Questions Applying to all Series Q.

Training and Development Portal. The RMA and C do not have this feature. How fast must the airflow switch contact close when using an RM? Hoe many cycles can be expected for the Series? Wire the relay coil and thermostat contacts in series on the low voltage side of the transformer. Skip to main content. What happens if the airflow switch does not close in honeywel allocated time?

Nonvolatile memory retains history files and sequencing status after power loss. Honeywell honeywrll tested to overcycles! On the RMG, there is no H. Product Code Quantity 1 2 3 4 5.

Yes, order part number There was an exception to this. There is no 24 VAC low voltage source available in any Series control.

Initiate was explained in the preceding question. If using a 7 second purge honegwell, it must close in 7 seconds. Note that timings for initiate, standby, purge, run, and post purge, are identical for all models. The power must be within certain tolerances for the control to remain on line.

I say surprisingly because by comparing the chart that shows timing for normal operating and wiring diagrams, the differences become very evident. The relay recognizes the wiring error and locks out.
