SETTING THE COUNTDOWN TIMER
This remote control system can operate with a built-in countdown timer when the transmitter is in the ON or THERMO modes
(THERMO or ON must be displayed on the screen).
When plugged into a standard 110-120 VAC receptacle, the remote
receiver operates on commands from the transmitter or from the slide
switch on the face of the receiver (This switch is to be used during a
power outage to operate the appliance manually).
• ON: will manually turn on the appliance.
• REMOTE: will allow use of handheld transmitter. If the system
does not respond to the transmitter on initial use, check the battery
positions in the remote. If that does not work, see the LEARNING
TRANSMITTER TO RECEIVER section.
• OFF: will disable the remote receiver.
• It is suggested that the slide switch be placed in the OFF
position if you will be away from your home for an extended
period of time.
The remote receiver is manufactured with a “dry contact” relay in its
circuitry that operates like an on/off switch. However, no power or
current passes from the 110-120 VAC input side to the wires leading
from the output side of the remote receiver.
RECEIVER
• Press and release the TIMER button. The minimum 0:15 minute setting on the LCD Screen will begin to ash.
• Press the UP or DOWN button on the transmitter to chose your countdown time. Available countdown times are 15 min, 30
min, 45 min, and 1 hour to 9 hours (alternating every 30 min).
• To initiate the countdown, press the SET button. If no button is pressed within 15 seconds, the setting will automatically be
accepted. The system will return to OFF mode when the countdown time expires. If the system is in THERMO mode, it will
cycle on and off based on the set temperature until the timer expires.
THERMO UPDATING FEATURE
This remote control has a temperature updating feature built into its software. The transmitter reads the room temperature every
2 minutes, then updates the room temperature on the LCD screen.
NOTE: The thermo feature operates the appliance whenever the room temperature varies a certain number of degrees from the set
temperature. This variation is called the “swing” or temperature differential. This feature lets the appliance turn off and on 2 ºF (1 ºC)
above or below the set temperature of the room. This is to cushion the number of times the appliance is turned on and off.
NOTE: This product is designed for use with an attended hearth appliance or re feature. Adults must be present when
the Control System is operating. DO NOT program or thermostatically set this Control to operate a hearth appliance
or re feature when Adults are not physically present. Furthermore, DO NOT leave the hearth appliance or re feature
burning unattended; it may cause damage or serious injury. If an Adult is going to be away from the hearth appliance or
re feature for any length of time, then the handheld/wall mount, receiver/control module and application should be in the
“OFF” position.

COMMUNICATION - SAFETY - TRANSMITTER - (C/S - T/X)
This remote control has a COMMUNICATION –SAFETY function built into its software to ensure the transmitter and receiver are
communicating normally.
In all operating modes, the transmitter sends an RF signal every fteen minutes to the receiver indicating that the transmitter is within
the normal operating range of 20 feet. Should the receiver NOT receive this signal, the receiver will begin a 2 hour countdown. If the
receiver does not receive a signal from the transmitter in 2 hours, the receiver will shut off the appliance. The receiver will then emit a
series of rapid “beeps” for a period of 10 seconds. Then after 10 seconds of rapid beeping, the receiver will continue to emit a single
“beep” every 2 seconds until a transmitter MODE Button is pressed to reset the receiver.
AUTO SHUT DOWN
This remote control has an auto shut down feature incorporated into its system. When the transmitter mode is in the ON position, the
appliance will only run for 9 hours. After that it will shut down. To reactivate the appliance, press the MODE button.
CP (CHILDPROOF) FEATURE
This remote control includes a childproof feature that allows the user to “lock-out” operations from the transmitter.
• To activate and de-activate the childproof feature, press and hold the SETTING button behind the battery cover for 5 seconds (The
letters “CP” will briey appear on the LCD screen when childproof mode is activated).
• “CP” will appear on the LCD screen if any button is pressed while childproof mode is engaged.
• When this mode is engaged, all auto settings go on without interruption (like thermostat). Only manual functions are prevented.
BATTERY LIFE
Life expectancy of the alkaline batteries in the transmitter should be at least 12 months. Check and replace all batteries:
• Annually.
• When operating range becomes reduced.
• When transmissions are not received by the remote receiver.
• If the hand held transmitter batteries measure less than 2.5 volts (Both batteries in combination).
ELECTRONIC SPARK SYSTEM CHECK
• Slide the 3-position button on the remote receiver to the ON position. The spark electrode should begin sparking to ignite the pilot.
After the pilot ame is lit, the main gas valve should open and the main gas ame should ignite.
• Slide the button to OFF. The main gas ame and pilot ame should both extinguish.
• Slide the button to REMOTE, then press the ON button on the transmitter to change the system to on. The spark electrode should
begin sparking to ignite the pilot. After the pilot is lit, the main gas valve should open and the main gas ame should ignite.
