To Change Batteries

1.Remove cover on the backside of the trans- mitter. Install 3 AAA batteries as shown inside the cover and reattach the cover.

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

3.Use functions as described in TRANSMIT- TER section.TroubleshootingStep 1. Locate LED light on valve.

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

Step 3. Failure codes may occur anytime after pilot burner is lit.Step 4. Sequence is failure code followed by light not blinking for 4 seconds.

Step 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:

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

Step 2. Switch the front two thermopile leads with the back two. Be sure the lead is connected to the spade with the white dot next to it (see Figure 4 ). 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:

Step 1. Confirm that the valve is not in REMOTE mode.

•If the valve is producing Error Code 8 and in REMOTE 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.

Step 2. Slide the Remote/Local switch to REMOTE and reprogram valve recognition (re- fer to in Operation section). The Error Code will clear itself after approximately 1 1/2 minutes and return to normal operation.
