Instructions for Comfort Control Valve
RADVTC Series
The Comfort Control valve allows remote control of
temperature, fan and flame appearance.
NOTE: The antenna should hang in free air away from
grounded metal.
Operation
1. If the manual switch is in remote position, switch it to
LOCAL. (Fig. 57)
2. Turn the pilotstat knob counterclockwise from OFF
to the PILOT position, push the knob down, and hold
in position. The pilot valve opens and allows gas to
flow to the pilot burner.
3. Push plunger on the piezo until the pilot burner is lit.
When the pilot burner is lit, the LED on the control
will come on after approximately 40 seconds and
will provide 1 short blink continuously in the normal
mode. When the light turns off which will be approxi-
mately 10 seconds after it has been continuously
red, the receiver/valve is fully powered.
4. Release the knob. The shaft will move upward. The
pilot burner should now stay burning. If the pilot
burner goes out, repeat step 2.
5. Turn the knob counterclockwise to the ON position.
If the manual switch is in the LOCAL position, the
main burner will turn on immediately.
6. ON the initial use of a transmitter, a recognition
operation is required between the receiver/valve
and transmitter. Change the switch from LOCAL
to REMOTE. Press the fan or flame button on the
transmitter within 30 seconds. The LED will blink
indicating the transmitter will now work with the re-
ceiver/valve. If the switch continues in the REMOTE
position, the transmitter will now control the main
valve, flame modulation level and fan control.
7. If the manual switch is in the LOCAL position, the
valve will be at the highest fixed pressure setting
and the fan will be at the highest fixed speed. The
transmitter will control the fan only.
Shut Off Procedure
If the manual switch is in the REMOTE position, the
transmitter can shut off the main burner and fan. How-
ever, the control is still on and a command from the
transmitter can turn on the main burner or fan.
To shut off the system, turn the pilotstat knob clockwise
to the OFF position. This action closes the main gas
and safety valves. The transmitter cannot turn on the
main burner or fan.
Transmitter Operation
Off Mode
In the OFF mode, the fireplace flame and fan are
off, the display will show OFF and displays the room
temperature. If the receiver is in REMOTE mode, the
fireplace will shut off.
On (Manual) Mode
In the ON mode, the room temperature, flame and fan
levels will be shown. MANUAL will appear next to both
the flame and fan icons.
When the control is in the ON mode, the flame and fan

down buttons. To change the flame level, press the
flame button followed by an arrow key. To change the
fan level, press the fan key followed by an arrow key.
Pushing the arrow key once will change the level by
one unit.

The shut off delay timer has a maximum of 2 hours and
a minimum of zero minutes. To change the timer level,
press the time key followed by an arrow key. Pushing
the key once will change the timer by 10 minutes.
