Carefully read these instructions. You could damage this product or cause a hazardous condition if you fail to follow these instructions.

Installation Tips

Wall Locations
The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.

Do not install thermostat in locations:

• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require conditioning
• Where there are dead spots or drafts (in corners or behind doors)
• Where there might be concealed chimneys or pipes

Subbase Installation

1. Horizontal Mount
2. Vertical Mount

• Installation Tip: Electrical Hazard
  Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.
• Mercury Notice
  All of our products are mercury free. However, if the product you are replacing contains mercury, dispose of it properly. Your local waste management authority can give you instructions on recycling and proper disposal.

Mount Thermostat
Align the 4 tabs on the subbase with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.

Battery Installation
Battery installation is optional if thermostat is hardwired (Rand C terminal connected to 24V power).

Important: High quality alkaline batteries are recommended. Rechargeable batteries or low quality batteries do not guarantee a 1-year life span.

Wiring

1. If you are replacing a thermostat, make note of the terminal connections on the thermostat that is being replaced. In some cases the wiring connections will not be color coded. For example, the red wire may not be connected to the R terminal.
2. Loosen the terminal block screws. Insert wires then retighten terminal block screws.

Installation Tip Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the subbase correctly or cause system operation issues.
Max Torque = 6in-lbs.

This thermostat is shipped from the factory to operate a conventional heating and cooling system. This thermostat will also operate a heat pump system. See the “heat pump” configuration step on page 10 of this manual to configure the thermostat for heat pump applications.

Wiring Tips

Caution: Electrical Hazard
Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

• Warning: All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code.
• C Terminal: The C (common wire) terminal does not have to be connected when the thermostat is powered by batteries.
• Wire Specifications: Use shielded or non-shielded 18-22 gauge thermostat wire.

Note: When connecting the MMW-2 to a PTAC, refer to the PTAC manufacturer instructions to enable remote thermostat operation.

Wiring Diagrams

1. Power supply
2. Jumper (not supplied) to connect GL and GH terminals.
3. Thermostat must be set to O and B to match the changeover valve, O is the cool changeover valve, B is the heat changeover valve.
4. The Aux Heat Relay is energized as the second stage of heat.

TypicallH/1CSvstem:2SpeedFan

Typical IH/IC System: 1 Speed Fan

Typical IH/IC Heat Pump System: 2 Speed Fan

Typical 2H/IC Heat Pump System: 2 Speed Fan

Note: Most PTAC systems support two speed fan operation. In a single speed fan PTAC system or conventional single speed fan system, a jumper should be installed between GLand GH on the thermostat.

Technician Setup

Fan OperationSetup 

• Electric: The thermostat operation jumper pin should be put in the ELEC position. This setting allows the thermostat to operate the fan during a call for heat. Most PTAC systems will require ELEC Fan Operation Setup.
• Gas: For systems that control the fan during a call for heat, put the jumper pin into the GAS position.

Technician Setup Menu 

1. Set the thermostat system switch to OFF.
2. To enter Tech Setup Menu.press and hold “+”and “-“together for 3 seconds.
3. Use “+”and”-“to select desired setting for each option.
4. Tap “+”and “-“together to move next option.
5. To exit Tech Setup Menu,move system switch or wait for 15 seconds.

Swing Setting

1. Set the thermostat system switch to the desired position (COOL or HEAT).
2. Press and hold “+”and “-“together for 3 seconds.
3. Use “+”and “-” to adjust desired swing setting (The display reads in tenths of a degree.)
4. To exit.move system switch or wait for 1 seconds.

 

The second stage of Heat will turn on at 2x the swing setting. The second stage will turn off when 1 x the swing is reached. For example, if the swing setting is 0.8° for heating and the thermostat is set at 70° F, the first stage will turn on at approximately 69.2° F. The second stage will turn on at 68.4°F and the first will turn off at 70.8° F.

RF Pairing

1. Receiver: Use a slender object into the hole and keep it depressed (for approximately 5 seconds) until the red LED starts flashing.
2. Transmitter: Turn the SYSTEM switch to OFF. Press and hold”+” and “-” together for 3 seconds to access the interface of room temperature calibration. Press and hold”+” and “-” together until”LE” is displayed on the LCD.Then press and hold “+” for 3 seconds , the transmitter will transmit the code signal. When the red LED on the receiver stops flashing, indicating that the code is successful.
