Sunamp Optimino xPlus Boiler + PV Key
The Sunamp Optimino xPlus Boiler + PV Key is an interchangeable control module that enables the Sunamp Thermino xPlus heat battery to be compatible with system boilers and future-proofs the system for solar PV integration without replacing the thermal storage unit.
Product Description
This Optimino key (part code VF02) converts the Thermino xPlus from boiler-only operation to boiler + solar PV capability using Sunamp's modular Optimino technology. Simply swap out the existing key controller to enable solar diverter compatibility, allowing the heat battery to accept low-temperature PV-heated water from myenergi EDDI solar diverters.
Key Features
- Dual energy source: Supports system boiler primary heating with solar PV as secondary heat source.
- Hot-swap technology: Change the Optimino key without draining the Thermino xPlus or interrupting heating.
- Solar diverter compatible: Works with myenergi EDDI, my-PV AC·THOR, 4-Noks power reducer, and Power Diverter Model 3.
- Future-proof design: Upgrade from boiler-only to boiler + PV at any point in the system lifecycle.
- Smart control: Integrated temperature sensing and prioritisation logic optimises boiler and PV charging.
- Legionella risk reduction: Maintains Thermino's low risk of water stagnation through active charging prioritisation.
Technical Details
- Optimino key part code: VF02 (Boiler + PV).
- Module dimensions (W × D × H): 25mm × 15mm × 25mm (compact plug-in cartridge).
- Supply voltage: 230V AC single-phase for boiler demand signal.
- Outputs: Dry contact relay or 230V output for boiler firing control; solar diverter command signal (0-10V or SSR compatible).
- Temperature sensors: Built-in PT1000 sensors for hot water top/return monitoring.
- Control logic: Prioritises boiler heating; diverts excess PV to storage when available; defaults to boiler if insufficient PV.
- Warranty: 2 years on controller module.
Compatible Heat Batteries
- Thermino xPlus 150: 150L equivalent, 1.8kW heating element.
- Thermino xPlus 210: 210L equivalent, 1.8kW heating element.
- Thermino xPlus 300: 300L equivalent, 1.8kW heating element.
System & Application Notes
- Compatible boilers: Any system boiler accepting 230V AC or dry-contact demand signal.
- Compatible solar diverters: myenergi EDDI, my-PV AC·THOR, 4-Noks power reducer, Power Diverter Model 3.
- Installation: Swap Optimino key at terminal block; no electrical work required beyond mains isolation (Sparks advised).
- Alternative keys: VF01 (boiler-only), or HP keys for heat pump compatibility (Vaillant VT02, Samsung SG02, Bosch BH02, Daikin DN02, etc.).
- Retrofit advantage: Enables existing boiler + Thermino systems to capture free solar heat without capital system redesign.
- Warranty: 10-year coverage on Thermino heat cell core (heating element); 2-year coverage on Optimino key.
