Fan Override During Auto Mode

Auto Mode

In the AUTO mode, the room temperature, set tem- perature, ﬂame and fan levels will be shown. AUTO will appear next to both the ﬂame and fan icons.

When the control is in the AUTO mode, the main burner will turn on/off or modulate based on the heat needed to maintain the set temperature. The ﬂame level will change automatically to optimize the heat output needed to maintain the set temperature. To change the set temperature, press the up or down key. Pushing a key once will change the temperature by one degree.

In the AUTO mode, the fan speed will increase with increasing ﬂame height or decrease with decreasing ﬂame height. “AUTO” is displayed next to the ﬂame and fan icons.

If a lower or higher fan speed is desired when operating in the AUTO mode, the fan speed can be overridden by pushing the fan button followed by the up or down key. Pushing a key once will change the fan level by one unit. In this mode “AUTO” is displayed next to the ﬂame icon and “MANUAL” is displayed next to the fan icon.

Change Between F/C Temperature Units

Push the up and down arrow keys simultaneously for at least 3 seconds to toggle between Fahrenheit and Celsius units.

Disable Thermostat Function

To disable the thermostat function in the AUTO mode, push the time and down keys simultaneously for at least 3 seconds.

To Change Batteries

1.Remove cover on the backside of the transmitter. Install 3 AAA batteries as shown and reattach cover.

2.Once steps 1-3 in OPERATION are completed, receiver/valve and transmitter are now ready. Press any button on transmitter for recognition process to occur between the receiver/valve and transmitter.

3.Use functions as described in TRANSMITTER sec- tion.

Troubleshooting

1.Locate LED light on valve.

2.LED will blink after every valid command received by the transmitter; this is not an error.

3.Failure codes may occur anytime after pilot burner is lit.

4.Sequence is failure code followed by light not blink- ing for 30 seconds.

5.In the event of multiple failure codes, next failure code follows previous failure code by approximately 3 seconds.

If an Error Code 3 is observed while performing the testing, complete the following:

1.Make sure the spade connectors are pushed all the way on. If rhe Error Code 3 is still showing, then go to the next step.

2.Switch the front two thermopile leads with the back two. Be sure the white lead is connected to the spade with the white dot next to it. If the Error Code 3 is still showing, replace the thermopiles.

If an Error Code 8 is observed while performing the testing, complete the following:

1.Conﬁrm the valve is not in REMOTE mode.

•If the valve is producing Error Code 8 and in RE- MOTE mode, the valve is defective and should be replaced.

•If the valve is in LOCAL mode and producing Error Code 8, then go to the next step.

2.Slide the Remote/Local switch to REMOTE and teach the valve a transmitter (see item 6, page 32). The Error Code will clear itself after approximately 1.5 minutes and return to normal operation.
