Tucson 8702 DX Model Overview
Proflame GTMF System
Photo 1 – Proflame GTMF System
The Proflame GTMF is a modular remote control
system that directs the functions of Tucson DX. The
Proflame GTMF System is configured to control the
on/off main burner operation, its flame levels, and
provides Manual and Smart thermostatic control of
the hearth appliance. The system controls two
remotely actuated 120V/60Hz power outlets. The Fan
outlet controls the fan speed through six levels, and
the Auxiliary outlet either on or off. There is also an
additional constantly powered 120V/60Hz outlet. The
system has battery backup power for burner
operation and control during power outages
(see
page 25 for specifications)
.
Remote Transmitter
The Tucson DX comes equipped with a thermostatic
remote control transmitter. The easy to read LCD
display shows all functional abilities as well as a
childproof lockout and low battery indicator. It
displays room temperature readout, set temperature
readout and function status. The remote transmitter is
powered by three 1.5 volt AAA batteries. A Mode Key
is provided to index between the features and a
Thermostat Key is used to turn on/off or index
through thermostat functions.
Receiver
The Receiver accepts commands via radio frequency
from the Remote to operate the appliance. The
Receiver is powered (6V DC) by the Fan Control
Module and uses four 1.5 volt AA type batteries for
backup during power outages. The Receiver’s slider
switch is set to one of three positions: ON (Manual
Override), REMOTE (Remote Control) or OFF. The
ON selection turns the valve on (to high) if the
Remote becomes inoperative.
Fan Control Module
The Fan Control Module (FCM) is the main power
supply for the entire system when 120v AC is
available. The FCM is part of the blower assembly
(packaged separately). The FCM provides two 120V
remotely controlled outlets, and one constantly
powered outlet. The FCM allows the remote to
control the fan unit through 6 speeds and turns the
auxiliary outlet on and off. This module also powers
the Receiver and Ignition Module with 6v DC, making
the batteries in the Receiver a backup power source
expanding the life of the batteries. When 120V power
is not available the FCM will not operate.
The FCM is equipped with a three-prong (grounding)
plug for protection against shock hazard and should
be plugged directly into a properly grounded three-
prong receptacle. Do not cut or remove the grounding
prong from the plug.
Proflame DFC Ignition Module
This is the command center for the appliance. The
DFC Module allows the pilot to run in the Intermittent
(IPI) mode or the Constant (CPI) mode. It signals the
burner to light or shut down and provides the ignitor
with the electricity needed for sparking. The DFC
Module is powered by the FCM when 120V power is
available or by the batteries in the Receiver during a
power outage.
SIT Modulating Gas Valve
The remote transmitter can modulate the valve and
the flame to 6 different settings between high and
low. You can modulate the flame via the remote
yourself or by setting the remote control to the Smart
Thermostat modulation mode. Smart mode means
that as the room temperature approaches the limit set
for shut down the valve will automatically gradually
step down the flame height. The reverse happens
when the room cools - the valve will automatically
gradually increase the flame height.
Pilot Assembly
The pilot assembly consists of a pilot hood, sensor
rod, and ignitor. The ignitor sends a spark to the pilot
hood which ignites the gas and lights the pilot. With
the pilot lit the sensor rod is engulfed by the flame,
flame rectification occurs and the appliance remains
lit. If the sensor does not stay engulfed by the flame
the main burner will not light and the pilot will shut
down.
