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.

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

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

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.

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.

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.

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. The Error Code will 
clear itself after approximately 1.5 minutes and re-
turn to normal operation.
