2.4 Wiring and Terminal Designations
The Riseem STN615 features large terminal blocks for easy wiring. Refer to the diagram below for terminal designations:
Image 2.3: Detailed wiring diagram and terminal designations for the Riseem STN615 thermostat, including common, heat, cool, and fan connections.
| Terminal | Description |
|---|---|
| C | Common 24VAC (system power supply) |
| O | Reverse Valve Cool |
| B | Reverse Valve Heat |
| W | Heat relay stage 1 |
| W2 | Heat relay stage 2 |
| RH | 24VAC (system power supply) HEAT = RH to W |
| RC | COOL = RC to Y FAN = RC to G |
| G | Fan |
| Y | Cool relay stage 1 |
| Y2 | Cool relay stage 2 |
Note: If you have both RH/R and RC wires, remove the metal jumper wire on the thermostat. If only 2 wires are connected, the thermostat must be powered by batteries.
2.5 Power Supply
The Riseem STN615 thermostat offers dual power supply options:
- 24VAC Power: Connect to your HVAC system's 24VAC power supply.
- 2 AAA Batteries: Requires 2 AAA alkaline batteries (not supplied). These batteries provide a backup power source if a C-wire is not available, maintaining settings during a power outage.
A common wire (C-wire) is not required on most systems, but it is necessary for heat-only and cool-only systems when not using batteries.
