5. Installation
5.1 Pre-Installation Steps
- Turn off power: Locate your heating/cooling system's circuit breaker or fuse box and turn off the power to the system. This is a critical safety step.
- Remove old thermostat: Carefully remove the cover of your old thermostat. Note how the wires are connected to the terminals.
- Label wires: Use the provided wire tag stickers to label each wire according to its terminal designation (e.g., R, G, Y, W, C). This is crucial for correct re-installation.
- Remove old wallplate: Once wires are labeled and disconnected, remove the old thermostat's wallplate.
5.2 Mounting the New Thermostat
- Mount wallplate: Position the new thermostat's wallplate on the wall. Use the included screws and anchors to secure it. Ensure it is level for aesthetic purposes.
- Connect wires: Match the labeled wires from your system to the corresponding terminals on the new thermostat's wallplate. Insert each wire firmly into its terminal.
- C: Common 24VAC (system power supply)
- O: Reversing Valve Cool
- B: Reversing Valve Heat
- W: Heat
- RH: 24VAC (system power supply) - Heat = RH to W
- RC: Cool = RC to Y, Fan = RC to G
- G: Fan
- Y: Cool
Note: If you have separate RH and RC wires, remove the metal jumper wire between them on the thermostat base. If only 2 wires are used, batteries are required for power.
- Attach thermostat to wallplate: Align the thermostat body with the mounted wallplate and gently push until it clicks into place.
- Restore power: Turn the power back on at your circuit breaker or fuse box.

5.3 Power Supply
The S3001 thermostat can be powered by two methods:
- 24VAC Power: If your system has a common wire (C-wire), the thermostat will draw power from your HVAC system.
- 2 AA Batteries: If a C-wire is not available or not connected, two AA alkaline batteries (not supplied) are required. These batteries also provide backup power in case of a power outage, maintaining your settings.

6. Operation
The Riseem S3001 thermostat is designed for straightforward operation. The large LCD display shows the current room temperature and the set temperature.

6.1 Setting the Temperature
- Use the + (Up) and - (Down) buttons on the right side of the thermostat to adjust your desired temperature. The "Set At" temperature will flash as you adjust it and then stabilize after a few seconds.
- The temperature control range is 44°F to 90°F (7°C to 32°C).
6.2 Fan Switch
The FAN switch is located at the bottom left of the thermostat. It has two settings:
- ON: The fan runs continuously.
- AUTO: The fan runs only when the heating or cooling system is actively operating.
6.3 System Switch
The SYSTEM switch is located at the bottom right of the thermostat. It has three settings:
- COOL: The thermostat will operate your cooling system to maintain the set temperature.
- OFF: The heating and cooling systems are turned off.
- HEAT: The thermostat will operate your heating system to maintain the set temperature.
6.4 Temperature Swing (Cycle Rate)
The thermostat allows for separate adjustment of heating and cooling swing (cycle rate). This feature prolongs or shortens the temperature open time, contributing to energy savings and comfortable temperatures. Refer to the full operating manual for detailed instructions on adjusting this setting.
7. Maintenance
7.1 Battery Replacement
If your thermostat is powered by AA batteries, a low battery indicator will appear on the display when the batteries need to be replaced. To replace the batteries:
- Open the easy-change battery door located at the bottom of the thermostat.
- Remove the old AA batteries.
- Insert two new AA alkaline batteries, ensuring correct polarity.
- Close the battery door.
If your thermostat is C-wire powered, batteries are not strictly required for operation but can provide backup in case of power loss.
8. Troubleshooting
If you encounter issues with your Riseem S3001 thermostat, consider the following:
- No Display/Power: Check if the circuit breaker for your HVAC system is ON. If using batteries, ensure they are fresh and correctly installed. If C-wire powered, verify the C-wire connection.
- System Not Responding: Ensure the SYSTEM switch is set to HEAT or COOL, not OFF. Check wiring connections for looseness or incorrect placement.
- Incorrect Temperature Reading: Allow the thermostat to stabilize for a few minutes after installation. Ensure it is not exposed to direct sunlight, drafts, or heat sources that could affect its sensor.
- Fan Issues: Check the FAN switch setting (ON/AUTO).
