HONEYWELL REDLINK THM5320R (01) PDF Document

The installation procedure for the HONEYWELL REDLINK THM5320R wireless system is as follows:

1. Mount and wire the Equipment Interface Module (EIM).

2. Install batteries in all wireless devices (thermostat, remote control, sensors).

3. Link all devices to the wireless network.

4. Exit the wireless setup mode.

5. Customize the thermostat through the installer setup.

6. Mount the thermostat and outdoor sensor.

Note: If you have more than one EIM, thermostats are linked to specific EIMs. Optional accessories must be linked to each EIM separately.

To mount and wire the EIM for your HONEYWELL REDLINK THM5320R system:

1. Mount the EIM on a wall near the HVAC equipment, or on the equipment itself. Do not install it inside the HVAC equipment. Use the provided screws and anchors as appropriate for the mounting surface.

2. To wire the EIM, strip 1/4″ of insulation from the wires.

3. Insert the wires into the appropriate terminals as shown in the wiring diagrams.

4. To remove wires, press the tabs on the terminal block.

Important: Disconnect power before beginning installation to prevent electrical shock or equipment damage. All wiring must comply with local electrical codes.

The return air sensor maintains a safe indoor temperature (62° F in Heat, 82° F in Cool) if the thermostat loses power. To install it:

1. Drill a 1/4″ (6.4mm) hole in the return air duct.

2. Install the sensor on the return air duct at least 12″ (305mm) upstream from any ventilator, humidifier, or dehumidifier. Do not mount it downstream.

Note for hydronic applications: Use the C7189U1005 Remote Indoor Sensor and mount it in the living space instead.

Once system wiring is complete, install batteries in all wireless devices, ensuring correct polarity.

• Thermostat: Install 2 fresh AA batteries. For programmable models, also install the quick reference card.

5. When you are finished, press DONE to save your changes and exit.

The following tables describe the installer setup functions and options. The factory default is in bold.

Heat Pump Control with Electric Backup (Setup Functions 24-25):

This function uses an outdoor sensor to determine when to use the compressor and when to use electric backup heat. Above the auxiliary lockout temperature (e.g., 55°F), only the compressor and fan operate. Between the auxiliary and compressor lockout temperatures (e.g., between 55°F and 40°F), the compressor and fan operate normally, but if the compressor cannot reach or maintain the setpoint, the electric backup heat will also engage. Below the compressor lockout temperature (e.g., 40°F), only the electric backup heat and fan will operate.

Heat Pump Control with Fossil Fuel Backup (Setup Function 18):

This is for dual fuel systems and has three options:

• Option 0 (No Droop Control): Above the balance point (e.g., 40°F), only the compressor and fan operate. Below the balance point, only the fossil fuel backup heat operates.

• Option 1 (Droop Control): This is the default. If the room temperature drops (exceeds the droop setting in function 20), the compressor is deactivated and the fossil fuel backup heat is activated after a 3-minute delay.

• Option 2 (Droop Control with Aux Heat Lockout): Similar to Option 1, but also incorporates an auxiliary lockout temperature. Above this lockout temp (e.g., 55°F), only the compressor and fan operate. The droop control is active below this temperature.

Comfort/Economy (Setup Function 26):

This function (not available if fossil fuel kit function 17 is set to 0) controls how quickly auxiliary heat responds.

• Comfort: Auxiliary heat will respond quickly to meet the temperature setpoint.

• Economy: The system will wait longer before activating auxiliary heat, only turning it on if the setpoint is not reached within a reasonable time.

1. To begin the system test, press and hold the UP and DOWN arrow buttons simultaneously until the display changes (about 3 seconds).

2. The screen will show the system test number on the left and the system status on the right.

3. Press the UP or DOWN arrow to check the status of the current test.

4. Press NEXT to advance to the next test.

5. Press DONE to terminate the system test at any time.

CAUTION: Compressor protection (minimum off time) is bypassed during testing. To prevent equipment damage, avoid cycling the compressor quickly.

Mounting the Thermostat:

1. Detach the wallplate from the thermostat.

2. Position the wallplate on the wall, using the built-in level to ensure it is straight.

3. Mark the mounting hole locations.

4. Drill holes: 3/16″ for drywall, 7/32″ for plaster.

5. Insert the wall anchors.

6. Secure the wallplate to the wall with the mounting screws.

7. Attach the thermostat to the wallplate.

Mounting the Outdoor Sensor (Optional):

1. Choose a location on a vertical exterior wall, at least 6 inches below any overhang and protected from direct sunlight.

2. Before mounting, you can check the location. Hold the sensor where you intend to install it and press its CONNECT button. If the thermostat switches to display outdoor temperature and humidity, the location is good.

3. Mount the sensor bracket to the wall.

4. Place the sensor securely in the bracket, with the front of the sensor facing away from the wall.
