Honeywell does not recommend even trying to restore a clipped jumper.

Questions & Answers About – Honeywell’s 7800 Series Controls

Selectable relight or lockout on loss of flame. This page location is: Yes, but you will add 30 seconds to the pre-purge timing for each switch jumpered. Hoe many cycles can be expected for the Series? Training and Development Portal. When replacing an RA that used a low voltage thermostat connected to T and T terminals for the old Q base, and it is inconvenient to change to a honeywdll voltage controller, a 24 VAC coil relay and transformer can be added. This depends on the model of the RM relay selected.

If the circuit remains closed for the two minutes, the RMB and D will lockout. If using a 7 second purge timer, it must close in 7 seconds. The RMA and C do not have this feature. If a display is used, fault codes 67 or will appear. Does the Honsywell display have any control of the relay functions? Nonvolatile r7m890a1015 retains history files and sequencing status after power loss.

Is this to attract attention honeuwell something is wrong? Every insurance organization and approval body in the U. Yes, but a relay will have to be added. This Info-Tec will attempt to answer some of those questions.

Can a low voltage controller be used with the RM? They wire the same and functionally, are the same. The power must be within certain tolerances for the control to remain on line. If you consider the remote reset capability of the hoeywell as a control function, then the display has one controlling function.

Pilot Type intermittent Vibration 0. It depends on the length of the purge card timing. Component Recognized, File No. A pre-ignition interlock is any switch that must remain closed until pre-purge is completed. Provides level of safety, functional capability and features beyond conventional controls.

Microprocessor-based integrated primary burner control for automatically fired gas, oil or combination fuel single burner applications. This is very important. Testing Wireless Solutions Testing wireless transmitters link.

Initiate was explained in the preceding question. Second, note that the jumpers are not just wires. If JR3 is clipped, the control will lockout if the air flow switch does not close in the allotted time. There is an RMC made only for standing pilot applications. Mechanical relays are still used, but the coils and contacts are sealed to prevent dirt, dust, grease, or any contaminant from affecting them.

Now look at Figure 3. Can a RM be used with a standing pilot? Long enough to result in four complete air changes through the burner. You will have enhanced the safety of the system.
