Changing The Code

The control is radio frequency operated. A code (chosen from among 4,000 available codes) is preset for all valves, but can be changed if required (15 additional codes available). Change DIP switch position. (The DIP switch is located inside the hand held

control at the top of the battery compart- ment.) Then press the receiver's reset button until you hear a second (longer) signal. When pressing the button on the remote handset in the following 20 sec., the receiver learns the new code.

Shut-off Procedure

Battery Replacement

Remote handset battery needs to be changed when LED is dim. Battery life expectancy is 2 to 3 years. Replacement is recommended at the beginning of heating season. Battery needs to be changed when acoustic error message appears during ignition (see Identifying Error Signals from Receiver on page 23).

Changing Mode of Operation

Press the SET button quickly to change the mode of operation in the following order:

MAN,  to set the minute. TEMP, •Wait or press OFF to return to the manual mode. TEMP, TIMER.

Manual flame height adjustment (MAN ap- pears on display): Press Figure 16 - Control Panel for Hand-Held to turn on the fire (main burner) or to increase flame height.

Press to decrease flame or to go down to pilot only. The receiver acknowledges the transmission with an acoustic signal.

The day time temperature mode (Battery Replacement TEMP ap- pears on display): The sensor in the transmitter measures room temperature. The controller compares the room temperature with set tem- perature and sends a signal to the receiver to turn the gas valve motor up or down, to adjust the flame height accordingly.

The nighttime setback temperature ( Changing Mode of Operation TEMP appears on display): The sensor in the transmitter measures the temperature and adjusts it according to the nighttime setback temperature. There is a bigger temperature differential during this cycle.

Timer: The timer mode ( TIMER ) operates much like the temperature mode above. The timer setting allows you to set specific times for on and off. (There are 2 burner on and 2 burner off cycles every 24 hours.) If the reading for the nighttime temp. is "– – –", the motor will turn off the valve to standby pilot position and wait for the next burner on cycle. This display shows the setting tem- perature every 30 seconds.

Setting the Temperature

Select the desired mode of operation (day or night) by pressing the SET button briefly.

Hold the SET button until the display flashes.

• Set the temperature with the MAN,  TEMP,  TEMP, TIMER. or (40°F is the minimum temperature).

Wait or press OFF to go to temperature control mode.

If temperature control in moon times should be off (lower battery consumption), decrease the night temperature until "– – –" appears on display.
