4. Setup and Installation
Follow these steps for proper installation of your TS-1 Thermostat Station.
4.1 Mounting the TS-1
- Choose a suitable location for the TS-1, away from direct sunlight, heat sources, or drafts, which could affect temperature readings.
- Secure the TS-1 to a wall or flat surface using appropriate screws through the designated mounting holes.
4.2 Wiring to HVAC System
The TS-1 connects to your conventional cool-only HVAC system using standard thermostat wiring.

Figure 4.1: Rear view of the TS-1, showing the R, W, Y, G terminals for HVAC wiring.
- R (Power): Connect to the 24VAC common wire from your HVAC transformer.
- W (Heat): Not used for cool-only systems. Ensure this terminal is not connected.
- Y (Cool): Connect to the cooling call wire from your HVAC system.
- G (Fan): Connect to the fan control wire from your HVAC system.
Important: Always turn off power to your HVAC system at the circuit breaker before performing any wiring. If you are unsure about wiring, consult a qualified electrician or HVAC technician.
4.3 Connecting to Hydro-X Control System
The TS-1 connects to your Hydro-X Control System via a standard RJ12 cable.

Figure 4.2: Connection diagram of the TS-1 to the Hydro-X Control System.
- Connect one end of the RJ12 cable to the port labeled 'Addressing' on the TS-1.
- Connect the other end of the RJ12 cable to an available device port on your Hydro-X Control System.
- Once connected, the Hydro-X system should automatically detect the TS-1.
5. Operating Instructions
The TS-1 operates in conjunction with your Hydro-X Control System. Basic settings can be viewed and adjusted directly on the TS-1 unit.
5.1 Display Information
The TS-1 display provides the following information:
- Setpoint: The desired temperature you have set.
- Current: The current ambient temperature detected by the TS-1.
- Cool On/Off: Indicates if the cooling system is currently active.
- Fan: Indicates the status of the fan (On/Auto).
5.2 Adjusting Setpoint Temperature
Use the up/down arrow buttons next to the display to adjust the desired temperature setpoint. The Hydro-X system will then manage the cooling system to maintain this temperature.
5.3 Fan Control
Press the 'FAN' button to cycle through fan modes (e.g., Auto, On). Refer to your Hydro-X Control System manual for detailed fan operation settings.
6. Maintenance
The TS-1 Thermostat Station requires minimal maintenance to ensure optimal performance.
- Cleaning: Periodically wipe the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ventilation: Ensure that the ventilation slots on the unit are not obstructed to allow for proper airflow and accurate temperature sensing.
7. Troubleshooting
If you encounter issues with your TS-1 Thermostat Station, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| TS-1 display is blank. | No power to the unit or Hydro-X system. | Check power supply to the Hydro-X system and ensure the RJ12 cable is securely connected. Verify HVAC system power. |
| HVAC system not responding to TS-1. | Incorrect wiring; Hydro-X system issue; HVAC system fault. | Verify all wiring connections (R, Y, G) are correct and secure. Check the status of your Hydro-X Control System. Consult an HVAC technician if the HVAC system itself is not functioning. |
| Inaccurate temperature readings. | Sensor obstructed or located in an unsuitable environment. | Ensure the TS-1's ventilation slots are clear. Relocate the TS-1 if it is in direct sunlight, near a heat source, or in a draft. |
For further assistance, please refer to the Hydro-X Control System manual or contact FGI customer support.
