Modbus BMS integration

Standard Modbus RS-485 connection lets the SMAX integrate with any commercial BMS — Trend, Siemens, Tridium, Schneider. Real-time data exchange with the building’s wider plant.

Cascade scheduling

When 2 or 3 SMAX units are cascaded, the master controller staggers their operation — one base-load unit runs continuously, others kick in during peak demand windows (gym morning rush, hotel checkout, kitchen pre-service).

Solar PV priority

When the building has PV generation, the SMAX takes the surplus for hot water before grid export. Variable-speed compressor matches PV output. Big savings on facilities with sizeable rooftop arrays.

Anti-legionella cycle

Commercial-grade legionella management with logging for compliance. The booster element supports the heat pump for these cycles — meets HSE L8 / ACoP requirements with full audit trail.

CleverBloom can help

Cascade setup, BMS integration, and commercial commissioning is part of every CleverBloom SMAX install — we coordinate with your BMS contractor and provide an O&M manual at handover.

1 · Heat pump module (top)

Larger compressor than the Essenta, sized for commercial duty cycles. Pulls heat from the surrounding air or ducted air supply. Variable-speed inverter modulates from low to full output without on/off cycling.

2 · 450 L stainless steel tank

Larger capacity than residential models. Stainless steel inner tank with high-spec foam insulation. 589 L of usable hot water per heating cycle at 40°C delivery temperature — sized for peak demand in commercial buildings.

3 · Heat exchanger coil

A long coiled heat exchanger runs through the water tank. Refrigerant in the coil gives up its heat to the water. The water never mixes with the refrigerant.

4 · Booster element

A larger electric element than residential models provides rapid recovery during peak demand windows (gym morning rush, hotel checkout time, restaurant pre-service) and weekly anti-legionella cycles (65°C).

5 · Cascade capability

Two or three SMAX units can be cascaded together for very high demand. The smart controller staggers their operation — one runs as a base load, others kick in during peak. Up to ~1,800 L tank capacity in cascade.

6 · Smart controller + cloud

Wi-Fi enabled controller schedules charging on cheap-rate tariffs, prioritises solar PV, runs anti-legionella cycles, and provides commercial-grade BMS integration via Modbus.

7 · Ducting flange

Built-in 200 mm air duct flanges let the SMAX pull air from one room (kitchen, plant room) and exhaust it to another. Avoids cooling the room it sits in — important for commercial plant rooms with other equipment.

8 · CleverBloom can help

Sizing the right SMAX (or cascade of multiple units), planning the air ducting, integrating with PV, and connecting to a commercial BMS is a design conversation we have during the site visit.

Manufacturer warranty

Kronoterm warrants the heat pump and tank per their published policy — available at quotation. SMAX is a commercial-leaning product; expect longer warranty terms when registered with Kronoterm at install.

Annual service recommended

Air-filter clean, condensate-drain check, electrical contact check, app firmware update. About 1–2 hours per unit per year. Important for commercial sites where hot-water failure means lost trade.

Anti-legionella runs automatically

The unit raises tank temperature to 65°C on a programmable schedule (typically weekly) to kill any bacteria that might develop in stored water. Important for any property serving the public.

Cloud monitoring

CLOUD.KRONOTERM gives remote access to tank temperature, energy use, error codes, and cycle history. Particularly useful for B&Bs and salons where the owner isn't always on site.

No refrigerant top-ups

Sealed at the factory. No refrigerant maintenance under normal use. If a fault occurs in the refrigerant circuit, only a refrigeration-qualified engineer can open it — CleverBloom maintains a register of qualified service partners.

European manufacturer support

Kronoterm is a Slovenian company with 50 years of heat-pump experience. SMAX is independently verified by TÜV Rheinland in Germany. Spares and warranty work come via Kronoterm's European service network. CleverBloom handles UK design and project coordination.
