In the AUTO mode, the room temperature, set
temperature, flame and fan levels will be shown.
AUTO will appear next to both 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.
1. Locate LED light on valve. (Fig. 52)
2. LED will blink after every valid command received
by the transmitter; this is not an error.
3. Failure codes may occur any time after pilot burner
is lit.
4. Sequence is failure code followed by LED not
blinking for 30 seconds.
5. In the event of multiple failure codes, next failure
code follows previous failure code by approximately
three seconds.
If Error Code 3 is observed while performing the
testing, complete the following:
1. Make sure the spade connectors are pushed all the
way on. (Fig. 54) If Error Code 3 is still showing, go
to the next step.
2. Switch the front two thermopile leads with the back
two leads. (Be sure the white leads are connected
to the spades with white dots next to them.) If Error
Code 3 is still showing, replace the thermopiles.
If Error Code 8 is observed while performing the
testing, complete the following:
1. Confirm the valve is not in REMOTE mode. (Fig. 52)
• 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.
2. Slide the Remote/Local switch to REMOTE and
program the transmitter per Item 6, Page 31. The
Error Code will clear itself after approximately
1.5 minutes and return to normal operation.
The shutoff delay timer has a maximum of two (2)
hours, and a minimum of zero (0) minutes. To change
the timer level, press the timer key, then an arrow key.
Pushing the key once changes the timer by ten minutes.
To disable the thermostat function in the AUTO mode,
push the TIME and DOWN keys simultaneously for at
least three (3) seconds.
