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.

This remote control kit has a hand held transmitter that can be used as a remote on/off or as a thermostat. The transmitter display shows the current room temperature, target temperature, timer setting, on/off status, low battery indicator, current time, burner/valve operation and fan operation. Electrical ratings for the receiver are: 1 10 VAC, 60 Hz, 6 W.

If pertinent, see additional ﬁ 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 qualiﬁ 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. Modiﬁ cation of the remote control system or any of its components will void the warranty and may cause a ﬁ re hazard.

NOTE: The factory installed junction box in the gas ﬁ replace must be wired with 110 VAC before installing this kit. See Installation Instructions section.

CAUTION: All wiring should be done by a qualiﬁ 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 VAL VE OF THIS APPLIANCE.

FCC REQUIREMENTS

WARNING: CHANGES OR MODIFICATIONS TO THIS UNIT NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE COULD VOID THE USER’S AUTHORITY T O OPERATE THE EQUIPMENT.

NOTE: This equipment has been tested and found

to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

WARNING: TURN ELECTRICAL POWER OFF AT THE CIRCUIT BREAKER BEFORE BEGINNING THIS INSTALLATION.

Wire Colors

• Gas Valve - Millivolt or

Electronic Ignition ..............................................Red

• 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 ﬁ replace. Remove the knock-out from the plate and attach the Romex clamp (screws to the outside) (see 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 ﬁ re- place.

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.

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 1 10-120V AC. It plugs into a standard polarized duplex receptacle.

Locating Receiver and Operating Functions

This remote receiver can be positioned under the ﬁ rebox in the control compartment of the ﬁ replace if ambient temperatures do not exceed 170º F. This system is designed to control the following components:

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.

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 ﬂ ame control sole- noid.

4. Place washer on ﬂ ame control solenoid (see Figure 4).

5. Insert the correct plunger (blue - natural gas, red propane) into the ﬂ ame control solenoid (see Figure 4).

6. Thread the ﬂ 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.

5. Set the manifold pressure on the gas valve by rotating the ﬂ 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 off.

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 off 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/Communication-

Safety Features’ under ‘Transmitter Safety Features’ section. Communication Safety features shut down the ﬁ replace system when a potentially unsafe condition exists.

Important: Review ‘Auto Shutdown’ section. This safety feature shuts down the ﬁ replace after 9 hours of continu- ous 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.
