Step 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 receiver/valve. If the switch
continues in the REMOTE position, the transmit-
ter will now control the main valve, flame modu-
lation level and fan control.
Step 7. If the manual switch is in the LOCAL
position, the valve will be at the highest fixed
pressure setting. The transmitter will control
the fan only.
Shut Off Procedure
If the manual switch is in the REMOTE posi-
tion, the transmitter can shut off the main
burner and fan. However, 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
now cannot turn on the main burner or fan.

on the heat needed to maintain the set tempera-
ture. The flame level will change automatically
