For a house
Boiler, pellet boiler or heat pump – one or several zones.
No cable between the thermostat and the boiler
The boiler sits in the basement, a plant room or the far end of the home, and there is no thermostat cable run to the living area.
Large house with 8 wired zones
A new house with eight or more underfloor-heated rooms: every room wants its own temperature, and the installation must be tidy, reliable and expandable.
Two-storey house with a pellet boiler — two zones, two pumps/valves, no cables, no overheat
The house has two floors, each with its own circulation pump or valve, fed by a pellet boiler.
Radiators upstairs, underfloor downstairs — one system
The ground floor has underfloor heating with a manifold, the upper floor has radiators.
Run the water heater only when needed
The electric water heater keeps water hot 24 hours a day — including when nobody is home.
Holiday house: warm on arrival, protected all winter
The house sits empty for months.
For an apartment
Replacing the old thermostat, renovation without wall chasing, bathroom.
WiFi upgrade: replace only the thermostat
The heating works fine, but the old wired thermostat has no schedule and cannot be controlled from a phone.
Renovation without opening walls: fully wireless control
The walls are finished and the furniture is in place, but there is no heating control.
No cable between the thermostat and the boiler
The boiler sits in the basement, a plant room or the far end of the home, and there is no thermostat cable run to the living area.
Limiting the floor temperature
Parquet and vinyl floor coverings have a maximum permitted temperature — typically around 27-28°C.
Bathroom with humidity and ventilation control
After a shower the moisture lingers, the mirrors fog up and mould eventually appears.
Two independent zones with a shared heat source
Two zones — say a living floor and a bedroom floor, or two apartments sharing one boiler — must be heated independently, yet there is only one heat source.
Underfloor heating
Room by room, with a floor temperature limit.
A separate temperature in every room — multi-zone underfloor heating
The bedrooms overheat while the living room stays cold — the entire underfloor system is driven by a single thermostat and one temperature for the whole floor.
Heat pump with underfloor heating and cooling
The heat pump supplies low-temperature water and the system responds slowly.
Limiting the floor temperature
Parquet and vinyl floor coverings have a maximum permitted temperature — typically around 27-28°C.
Radiators upstairs, underfloor downstairs — one system
The ground floor has underfloor heating with a manifold, the upper floor has radiators.
Large house with 8 wired zones
A new house with eight or more underfloor-heated rooms: every room wants its own temperature, and the installation must be tidy, reliable and expandable.
Bathroom with humidity and ventilation control
After a shower the moisture lingers, the mirrors fog up and mould eventually appears.
Underfloor heating with a stable flow temperature – mixing valve
The boiler or heat pump supplies hotter water than the underfloor heating can take.
Underfloor heating and a fan coil in every room
Every room has underfloor heating and a fan coil.
Underfloor heating and an LG hydronic ceiling cassette – one thermostat
The room has underfloor heating and an LG hydronic cassette in the ceiling.
Fan coils
Heating and cooling, hotels and offices, AHU/VRF.
Fan coil with no control cable — FC22x/FC41 wireless connectivity
The fan coil unit is mounted where the temperature is not felt correctly, and there is no control cable run to the wiring center, the boiler or the heat pump.
Underfloor heating and a fan coil in every room
Every room has underfloor heating and a fan coil.
One thermostat for heating and cooling – heat pump, fan coils or boiler + chiller
The home has both heating and cooling.
Underfloor heating and an LG hydronic ceiling cassette – one thermostat
The room has underfloor heating and an LG hydronic cassette in the ceiling.
Fan coil with no cable to the boiler / heat pump – wireless demand with TB01
The fan coil is in a room with no control cable run from the boiler, heat pump or wiring centre, yet the source must only start when the fan coil needs heating or cooling.
Hotel rooms with fan coil units
Every room needs its own temperature control, but wiring dozens of rooms and maintaining them must stay simple, and guests must not be able to derange the system settings.
Controlling AHU/VRF systems and air handling units
An air handling unit with a DX kit has no convenient room-side control.
Ventilation
Air handling units (AHU/VRF), heat recovery units, free cooling, bathroom humidity and ventilation.
Controlling AHU/VRF systems and air handling units
An air handling unit with a DX kit has no convenient room-side control.
Heat-recovery ventilation (HRV/ERV) with bypass and frost protection
An HRV must modulate two fans, open a summer bypass for free cooling and protect the exchanger from frosting at low outdoor temperatures — functions that normally require the manufacturer’s dedicated controller.
AHU economizer — free cooling with outdoor air
An air handler cools mechanically even when it is cooler outside than inside — pure wasted energy.
Bathroom with humidity and ventilation control
After a shower the moisture lingers, the mirrors fog up and mould eventually appears.
Heat pumps
Underfloor + fan coils, automatic season, two heat sources.
One thermostat for heating and cooling – heat pump, fan coils or boiler + chiller
The home has both heating and cooling.
Heat pump with underfloor heating and cooling
The heat pump supplies low-temperature water and the system responds slowly.
Reversible air-to-water heat pump — control with automatic changeover
A heat pump manufacturer needs a ready controller for a reversible machine: compressor, reversing valve, circulation pump and a modulating valve/fan, with separate heating and cooling settings and changeover from a remote contact.
Large tank with two heat sources — heat pump plus gas boiler boost
A large storage tank is heated by two sources: a heat pump, efficient at low temperature, and a gas boiler that boosts to a higher one.
Multi-zone control
From 2 to 8 zones – wired or wireless.
A separate temperature in every room — multi-zone underfloor heating
The bedrooms overheat while the living room stays cold — the entire underfloor system is driven by a single thermostat and one temperature for the whole floor.
Two independent zones with a shared heat source
Two zones — say a living floor and a bedroom floor, or two apartments sharing one boiler — must be heated independently, yet there is only one heat source.

Protection against misuse and remote management.
Protect your rental property's heating from tenant misuse
A tenant moves the room thermostat somewhere unrepresentative of the room — next to a window, out on a balcony — and the boiler ends up running non-stop chasing a false reading, driving up bills and wearing out the equipment.
Manage a holiday-let's heating remotely between guest stays
A holiday-let sits empty between bookings.
Consistent, managed heating across shared student housing
A shared student house or hall of residence has several rooms, each with different occupants and habits.

Rooftop unit (RTU) — two heating and two cooling stages
A rooftop unit for a shop or hall has two heating and two cooling stages.
Walk-in cold room with defrost and alarm
A walk-in cold room needs more than temperature holding: cyclic defrost with drip time, fan delay after defrost, pause on an open door and an over-temperature alarm.
AHU economizer — free cooling with outdoor air
An air handler cools mechanically even when it is cooler outside than inside — pure wasted energy.
Heat-recovery ventilation (HRV/ERV) with bypass and frost protection
