What is the thermoBox controller used for?
The ThermoBox is a controller that allows for the remote control and monitoring of heating appliances, such as boilers, stoves, electric radiators and other heating systems. It has a potential-free contact, which allows it to switch devices operating at lower voltages as well. Thanks to its ability to integrate with a mobile app, users can control the temperature in their rooms.
What is the maximum power that the thermoBox can switch?
3,680 W for a resistive load, e.g. a heater, which equates to 16 A at 230 V.
How many sensors, and of what length, can be connected to the thermoBox controller?
Two sensors can be connected to the thermoBox controller: the main sensor and an optional safety sensor. The temperature will be read from the main sensor. The maximum length of each is 15 metres. The safety sensor is used as an additional safeguard against overheating; for example, it can limit the temperature of a wooden floor above underfloor heating.
Where should the thermoBox probe(s) be installed?
To ensure reliable indoor measurements, the main sensor should be positioned at a height of approximately 1.5 metres, due to the temperature difference between the floor and the ceiling, and away from areas exposed to direct sunlight. It should not come into contact with any fixtures. If a safety sensor is being fitted – most commonly used in the case of wooden floors – it should be placed in a conduit directly beneath the protected floor layer.
Can a button be connected to the thermoBox?
Yes, you can connect a monostable (bell-type) button – without backlighting.
Will the thermoBox controller resume temperature control after the power has been restarted?
It is possible to set the behaviour – the temperature controller can be switched off or on, or it can revert to the state it was in before the power failure (i.e. the ‘last’ option).
How do you install the thermoBox controller for a water-based underfloor heating system?
A thermoBox must be fitted in every room or section that is to be controlled independently. Thermoelectric actuators and the appropriate controller (e.g. switchBox LIGHT, switchBoxD or switchBoxDC, depending on the actuator voltage (230V or 12–24V DC)) are installed on the heating loops in the room in question. A switchBoxDC with a potential-free contact is fitted near the boiler, whilst a switchBox LIGHT or switchBoxDC is fitted near the circulation pump, selected to match the device’s voltage.
Each thermoBox requires the configuration of three wireless control actions – one for the actuator in a given section, one for the boiler and one for the pump. When the thermoBox detects a need for heating, it sends a ‘switch on for 5 minutes’ signal, which is repeated every 3 minutes. This solution, based on the ‘switch on for a set time’ action, prevents a situation where, in the event of communication problems, the heating remains switched on permanently. If multiple thermoBoxes are operating within the system as thermometers in different rooms, controlling them does not interfere with the operation of the boiler and pump, as might happen with standard ‘on/off’ commands.
Can I connect the thermoBox to another thermostat?
The thermoBox is a thermostat in its own right; it is not possible to run it in parallel with another device.
Can I connect the thermoBox to a gas boiler?
Most modern gas boilers have a voltage-free input for connecting an external thermostat, to which the thermoBox’s relay output can be connected, whilst the thermoBox sensor should be placed in a representative room – the system will regulate the temperature based on readings from this sensor. Please note that the thermoBox is a two-state controller (on/off), which will switch the boiler on or off according to the set temperature (via the wBox app) measured in the room. However, it is not possible to remotely adjust the circulation water temperature, which is set (manually) on the boiler (e.g. 55°C).
