🔗 Compatibility Guide

Compatible Topside Panels

This board is compatible with Lite Duplex Digital topside panels. Contact Parts4Tubs or refer to manufacturer documentation for specific panel part numbers compatible with your system.

Replaces Part Numbers

This PCB replaces earlier versions of the SUV system board. Verify your existing board’s chip number (located on white label near centre of board) matches the SUVR1 series before ordering. Contact Parts4Tubs for compatibility verification.

Compatible System Components

This board uses integrated dual sensors in the heater assembly for temperature and hi-limit protection. Contact Parts4Tubs or refer to manufacturer documentation for compatible heater assemblies and sensor kits.

🎛️ DIP Switch Configuration

The SUV PCB features a 10-position DIP switch bank for system configuration:

Switch	Function	OFF Position	ON Position
S1	Test Mode	Normal operation	Test mode active
S2	N/A	OFF (required)	–
S3	Panel Option	Digital Duplex	Mini Panel
S4	N/A	OFF (required)	–
S5	N/A	OFF (required)	–
S6	Frequency	60Hz	50Hz

S8	Temperature	Fahrenheit (°F)	Celsius (°C)
S9	N/A	OFF (required)	–
S10	Amperage/Voltage	50 Amp / 240V	30 Amp / 120V

⚠️ For UK Installation: Set S6 to ON (50Hz) and S8 to ON (°C). S10 should typically be OFF for 240V operation.

🛠️ Installation Requirements

⚠️ IMPORTANT: All electrical work must be carried out by a qualified electrician in accordance with BS 7671 (IET Wiring Regulations).

Pre-Installation Checklist

• [ ] Verify your existing board’s chip number matches SUVR1 series
• [ ] Confirm topside panel compatibility
• [ ] Disconnect all power at the main breaker
• [ ] Allow capacitors to discharge (wait minimum 5 minutes)
• [ ] Photograph existing wiring and DIP switch positions

⚠️ Safety Warnings

Electrical Safety

⚠️ ALWAYS disconnect power at the main breaker before any work on the control system.

⚠️ A Ground Fault Circuit Interrupter (GFCI) or Residual Current Device (RCD) is mandatory – must be installed at least 1.5m from the spa.

⚠️ Do not permit any electrical appliance within 1.5m of the spa.

⚠️ All electrical connections must be made by a qualified electrician.

⚠️ Use minimum 6 AWG copper conductors only for main power connections.

Water Safety

⚠️ Maximum safe water temperature is 40°C (104°F).

⚠️ Suction fittings must be rated for the system’s maximum flow rate.

⚠️ Each pump requires a minimum of two suction fittings or one fitting plus skimmer.

🔍 Power-Up Procedure

After installation, follow this sequence:

1. Fill spa to correct operating level with all valves open
2. Vent air from pumps by loosening discharge union nuts briefly
3. Apply power – display will show countdown sequence
4. Priming mode – “Pr” appears on display (4-5 minutes)
5. Prime pumps – Press Jet button to activate pumps
6. Exit priming – Press Temp button or wait for automatic exit
7. Temperature display – Actual temperature shows after approximately 1 minute of water flow
8. Verify voltage – Check voltage at terminal block under load

⚠️ Do not allow pumps to run for more than 2 minutes without priming. Turn off and re-vent if water is not flowing.

❓ Frequently Asked Questions

Q: How do I identify if this board fits my spa? A: Locate the chip number on the white label near the centre of your existing board. It should show SUVR1A, SUVR1B, SUVR1C, STD05R1, or similar. The board should visually match the replacement.

Q: Is this board plug-and-play? A: No. Circuit boards require correct DIP switch configuration and may need voltage setup. Copy DIP switch settings from your original board, or configure according to your system requirements.

Q: Can I use a 2-speed pump on the Pump 2/Blower output? A: No. The Pump 2/Blower output only supports 1-speed devices. Only Pump 1 supports 2-speed operation.

Q: What topside panels work with this board? A: This board is compatible with Lite Duplex Digital panels. See the compatibility table above for specific part numbers.

Q: My spa trips the breaker after installing this board – why? A: This is commonly caused by incorrect voltage configuration. Verify DIP switch S10 is set correctly for your supply voltage (OFF for 240V, ON for 120V). Also check that no wiring is crossed.

Q: Does this board have persistent memory? A: Yes. The board retains temperature settings and configuration without a battery, though time-of-day will reset after power loss.
