Amana GWT01NE Thermostat Installation Manual

Installation Tips

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

Installation Tip: Pick an installation location that is easy for the user to access. The temperature of the location should be representative of the building.

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

For vertical mount, put one screw on the top and one screw on the bottom.

For horizontal mount, put one screw on the left and one screw on the right.

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

Mercury Notice: All Amana products are mercury free. If the product being replaced contains mercury, dispose of it properly according to local waste management authority instructions.

Thermostat Application Guide

A trained, experienced technician must install this product. Carefully read these instructions. Failure to follow these instructions could damage the product or cause a hazardous condition.

Wiring

1. If you are replacing a thermostat: Make note of the terminal connections on the thermostat being replaced. In some cases, 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.

Wiring Tips:

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

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.

Warning: All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code.

Conventional vs. Heat Pump Wiring

Note: When connecting the GWT01NE to a PTAC, refer to the PTAC manufacturer instructions to enable remote thermostat operation.

Note: When installing the GWT01NE thermostat onto a Distinctions branded PTAC, please ensure dip switch S3 is set to the UP position and dip switch S9 is set to the DOWN position. After setting the correct dip switch positions, please unplug the unit for 10 seconds to save the settings.

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 Diagrams

Typical 1H/1C System: 2 Speed Fan

Typical 1H/1C Heat Pump System: 2 Speed Fan

Typical 2H/1C Heat Pump System: 2 Speed Fan

Typical 1H/1C System: 1 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 GL and GH on the thermostat.

Technician Setup

Fan Operation Setup

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

Use the thermostat system switch to OFF.

Tech Setup Steps:

1. To enter Tech Setup Menu, press and hold "+" and "-" together for 3 seconds.
2. Use "+" and "-" to select desired setting for each option.
3. Tap "+" and "-" together to move to the next option.
4. 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 the desired swing setting (The display reads in tenths of a degree).

4. To exit, move system switch or wait for 1 second.

Swing Settings Explained

The swing setting, often called "cycle rate", "differential" or "anticipation" is adjustable. A smaller swing setting will cause more frequent cycles, and a larger swing setting will cause fewer cycles.

Cooling Swing: The cooling swing setting is adjustable from 0.2° to 2°. For example, a swing setting of 0.5° will turn the cooling on at approximately 0.5° above the setpoint and turn the cooling off at approximately 0.5° below the setpoint.

Heating Swing: The heating swing setting is adjustable from 0.2° to 2°. For example, a swing setting of 0.5° will turn the heating on at approximately 0.5° below the setpoint and turn the heating off at approximately 0.5° above the setpoint.

Swing Setting for Second Stage: The second stage of heat will turn on at 2x the swing setting. The second stage will turn off when 1x 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.

Thermostat Quick Reference

LCD: Displays the current room temperature.

Set At: Displays the user-selectable setpoint temperature.

Fan Switch: Controls fan operation.

System Switch: Controls system operation (AUTO, COOL, HEAT, OFF).

Setpoint Buttons: Used to adjust the desired temperature.

System operation indicators: "On" will display when the COOL or HEAT is active.

Battery Installation

Insert 2 AAA Alkaline batteries (included). High quality alkaline batteries are recommended.

Battery installation is optional if the thermostat is hardwired (R and C terminals 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.
