RCT-MLT-II Remote Control Kits
- Installation and Operating Instructions -
INTRODUCTION
The remote control system can be operated thermostati­cally or manually from the transmitter. The system oper­ates on radio frequencies (RF) within a 20 foot range. Can be used with DSI, IPI or Standing Pilot systems.
can be used as a remote on/o󰀨 or as a thermostat. The
transmitter display shows the current room temperature, target temperature, timer setting, on/o󰀨 status, low bat­tery indicator, current time, burner/valve operation and fan operation. Electrical ratings for the receiver are: 110 VAC, 60 Hz, 6 W.
If pertinent, see additional replace wiring diagrams on
pages 9 to 11.
INSTALLATION PRECAUTIONS
This remote control kit is tested and safe when installed in accordance with this installation manual.
Installation of this kit MUST be done by a qualied service technician.
NOTE: A manometer MUST be used to set the
manifold pressure on the gas valve.
It is the responsibility of the installer to read all instruc­tions before starting installation and to follow these
instructions carefully during installation. Modication of
the remote control system or any of its components will
void the warranty and may cause a re hazard.
NOTE: The factory installed junction box in the gas replace must be wired with 110 VAC before install­ing this kit. See Installation Instructions section.
CAUTION: All wiring should be done by a qualied
electrician and shall be in compliance with local codes and with the National Electric Code ANSI/NFPA No. 70­current (in the United States), or with the current CSA C22.1 Canadian Electric Code (in Canada).
WARNING: DO NOT CONNECT 110-120 VAC WIRING TO THE GAS CONTROL VALVE OF THIS APPLIANCE.
FCC REQUIREMENTS

However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turn-
ing the equipment o󰀨 and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit dif­ferent from that to which the receiver is connected.
- Consult the dealer or an experienced radio TV techni­cian for help.

• Fan/Blower - 110 VAC .........................Plug from Fan
• Flame Controller - HI/LO solenoid ..................Orange
NOTE: Some appliances do not have a cover plate. In­stead, there is a hole through which the Romex clamp is attached to the outer wrap.
1. Remove the electrical cover plate from the lower side
of the replace. Remove the knock-out from the plate
and attach the Romex clamp (screws to the outside) (see Figure 1).
Figure 1
2. Feed the electrical service wires through the Romex
clamp and secure the wires to the clamp.
3. Using the wire nuts provided, connect the service wires
to the junction box. The black wires to the black service wire, the white wires to the white service wire, and the service ground wire to the ground stud of the junction box.
4. Re-attach the cover plate to the outside of the replace.
WARNING: LEAVE ELECTRICAL POWER OFF AT THIS TIME. DO NOT RESTORE POWER UN­TIL THE REMOTE CONTROL SYSTEM IS COM­PLETELY INSTALLED.
REMOTE RECEIVER
Important: The remote receiver should be positioned close to front in right or left corner where ambient temperatures do not exceed 170º F.
The remote receiver is powered by 110-120VAC. It plugs into a standard polarized duplex receptacle.
RECEIVER WIRING INSTRUCTIONS
Incorrect wiring connections WILL cause damage to the gas valve or electronic module operating the gas appli­ance and may also damage the remote receiver.
Wiring Flame Function (Standing Pilot, DSI, IPI)
Connect the remote receiver by connecting the two red wires leading from the remote receiver to the red and brown remote wires labeled “FOR USE WITH REMOTE OR WALL SWITCH ONLY”. See Figure 2.

Alternative Wiring for units with a wall switch
Disconnect the wall switch wire from the TH terminal on the valve and connect this wire to male connector supplied on the receiver. Connect remaining female connector from receiver to the TH terminal on the valve.
Adding Optional Fan/Blower
Plug 2-prong fan cord directly into the 3 prong polarized plug on the back of the receiver (see Figure 3). This receptacle output is 110/120 VAC, 3 AMP.

NOTE: If junction box contains 2-prong receptacles, a standard 3 to 2 prong adapter will be required to be obtained from an independent source.
Locating Receiver and Operating Functions
This remote receiver can be positioned under the rebox in the control compartment of the replace if ambient tem-
peratures do not exceed 170º F. This system is designed to control the following components:

NOTE: All steps required for installation of the ame controller MUST be done by a qualied gas service technician.
Installing Flame Control Solenoid
1. Remove the screw and knob from the variable regulator
and discard.
2. Unscrew the nut from the regulator and discard.
3. Remove the bag containing a washer and blue and red
plungers from the side of the ame control solenoid.
4. Place washer on ame control solenoid (see Figure 4).
5. Insert the correct plunger (blue - natural gas, red - pro-
pane) into the ame control solenoid (see Figure 4).
6. Thread the ame control solenoid with correct plunger
into the thread hole in the variable regulator. Turn one to two turns only. Do not tighten or damage may occur.
3. Plug the remote receiver into the 110/120 VAC power supply.
4. Light the replace as directed in the Owner’s Manual.
5. Set the manifold pressure on the gas valve by rotating
the ame control solenoid. Adjust until the reading on
the manometer is 3.5 inches w.c. for natural gas, or
10.0 inches w.c. for LP.
6. Tighten the jam nut (see Figure 4) to the face of the variable regulator body.
7. Turn the main gas knob on the gas valve OFF.
8. Remove the manometer from the pressure tap and screw the tap closed.

NOTE: The remote receiver will only respond to the transmitter when the 3-position slide button on the remote receiver is in the Remote position. If the system does not respond to the transmitter on initial use, see section Matching Security Codes.
1. With the slide switch in the ON position, the system is on.
2. With the slide switch in the REMOTE position, the system only operates if the remote receiver receives commands from the transmitter.
3. With the slide switch in the OFF position, the system
is o󰀨.
NOTE: The slide switch should be placed in the OFF po­sition if you will be away from your home for an extended period of time. Placing the switch in the OFF position also
functions as a safety “lock out” by turning the system o󰀨
and rendering the remote receiver inoperative.
TRANSMITTER
Important: Before operating remote control, transmit­ter and receiver must have matching security codes.
See section ‘Matching Security Codes’.
Important: Review ‘Thermo-Updating/Communication­Safety Features’ under ‘Transmitter Safety Features’ section. Communication Safety features shut down the
replace system when a potentially unsafe condition
exists.
Important: Review ‘Auto Shutdown’ section. This safety feature shuts down the replace after 9 hours of continu­ous operation, in ON mode only.
Important: New or fully charged batteries are essential for proper operation of the multi-function transmitter. The transmitter operates on 2 AAA-size 1.5V batteries. Use Alkaline batteries for longer battery life and maximum operational performance.
Insert 2 AAA-size 1.5V batteries into the battery compart­ment on the back of the transmitter. When the batteries are correctly inserted, the screen will display numbers (see Figure 7 for LCD Display Screen).
NOTE: If the transmitter is activated from a very cold condition it may be necessary to allow the transmitter to stabilize to room temperature (could take up to 15 min­utes) before accurate room temperatures are displayed on the screen.
NOTE: LCD screen is equipped with a “backlite” for easier viewing of LCD screen. Backlite illuminates when a function button is depressed. After 5 seconds elapses, LCD screen will return to its normal state.
