2 Blink Status Details

DVC 500-C

Firebox Static Pressure

Safety Protocol

The DVC-500 operates with a negative pressure firebox as a safety feature. The control continuously adjusts the draft motor speed to maintain a safe firebox negative static.

NOTE: Observe the intensity of the Draft Motor light on the control panel in comparison with the Feed Motor light when it is on. When the appliance and venting system are clean, the indicator light is much dimmer than the others. This is because there is lower voltage flowing to the draft motor. As ashes build up, the light will get brighter because the draft motor needs to run faster in order to maintain the negative pressure in the firebox. When the indicator light for the draft motor appears as bright as the rest of the lights, it is a good indication that it's time to clean the appliance and the venting.

If the circuit board is flowing full line voltage to the Draft Motor, and the negative pressure in the firebox is too low, the following safety protocol will begin.

Stage 1

When the safety switch senses a loss of negative pressure in the firebox for more than 68 seconds the following happens:

The combustion blower will reduce in speed. During this cool down period the feeder is allowed to opreate. If needed, the feeder can opreate for up to 3 minutes.

After 72 minutes, if the safety switch has not sensed another pressure loss, the unit will automatically go back to the control board setting.

If the safety switch senses a loss of negative pressure anytime during the STAGE 1 Protocol, the unit automatically goes to the STAGE 2 Protocol

Stage 2:

If Stage 1 has already begun and the negative pressure is lost:

The status light will start to blink ( 2 blinks ). The combustion blower and feeder motor will shut off. These motors will remain off for a 5 minute cool- down period. After five minutes, those components will restart at a reduced feed rate ( 30 seconds max.) for 72 minutes.

After 72 minutes, if the safety switch has not sensed another pressure loss, the unit will automatically go back up to Stage 1.

The status light will continue to blink (2 blinks) throughout Stage 1 and Stage 2.

If the safety switch senses a loss of negative pressure anytime during the Stage 2 Protocol, the unit automatically goes to the Stage 3 Protocol.

Stage 3:

During stage 2, if another loss of negative pressure is sensed;

The status light will continue to blink 2 blinks. The Distribution Blower will be cycling "high" to "low" as an audible warning.

The Combustion Blower and Feeder Motor will shut off.

When the unit reaches Stage 3 these motors will not restart.

The Draft Motor will continue to run at maximum voltage, but the fire will go out.

[At any time, the 2 blink status can be reset by disconnecting the power to the unit for a few seconds.]

CAUTION

Resetting a 2 Blink Status likely indicates that service is required.

Clean the appliance and the venting system thoroughly. If the error persists, contact your dealer for more advanced service.
