The Danfoss BasicPlus2 WT-T Room Thermostat is a device designed for individual room temperature control, primarily used in conjunction with Danfoss TWA actuators for floor heating systems. This thermostat allows users to set and maintain a desired room temperature, contributing to comfort and energy efficiency.
The BasicPlus2 WT-T operates as a room thermostat, sensing the ambient temperature and controlling a connected heating actuator to achieve the user-defined setpoint. It functions by opening or closing an electrical circuit to the actuator, which in turn regulates the flow of heating medium to the floor heating loops. The thermostat is designed for straightforward operation, featuring a simple dial knob for temperature adjustment.
The core function of the BasicPlus2 WT-T is to provide a user interface for setting the desired room temperature. Once the temperature is set, the thermostat continuously monitors the actual room temperature. If the room temperature falls below the setpoint, the thermostat activates the connected heating actuator, causing it to open and allow heat to flow into the room. Conversely, if the room temperature rises above the setpoint, the thermostat deactivates the actuator, causing it to close and reduce heat input. This on/off control mechanism ensures that the room temperature is maintained within a comfortable range around the setpoint.
The thermostat's operation is dependent on its connection to a TWA actuator, which can be either Normally Closed (NC) or Normally Open (NO). The wiring configuration varies based on the type of actuator and the location of the power supply relative to the thermostat or actuator. This flexibility allows for integration into various heating system setups. The thermostat's relay has a maximum load capacity, which is crucial to observe during installation to prevent damage to the device.
The BasicPlus2 WT-T is designed for ease of use and integration into a home environment. Its primary usage feature is the intuitive dial knob, which allows occupants to easily adjust the desired room temperature. The thermostat's design is discreet, intended to blend into the room's aesthetics.
Installation of the thermostat should be performed by an authorized electrician to ensure safety and correct functionality. The recommended installation height is approximately 1.5 meters above the floor, and care should be taken to avoid locations exposed to direct sunlight, draughts, or other heat sources such as televisions, as these can interfere with accurate temperature readings.
The process of setting up the thermostat involves carefully removing the cover and dial knob, connecting the necessary wiring, and then mounting the back plate to a standard wallbox using the provided screws. Once the wiring is complete and the back plate is secured, the cover can be reattached. The wiring diagrams provided in the manual illustrate different connection scenarios, depending on whether the power supply is closer to the room thermostat or the actuator, and whether a Normally Closed (NC) or Normally Open (NO) actuator is used. This detailed guidance ensures proper electrical connection for optimal performance.
The thermostat is intended for continuous operation, providing consistent temperature regulation. Users can simply turn the dial to their preferred temperature, and the thermostat will work to maintain that level of comfort. Its robust construction, using ABS + PC materials for the shell, ensures durability in a typical indoor environment.
The BasicPlus2 WT-T Room Thermostat is designed for minimal maintenance, focusing on reliable long-term operation once correctly installed. The key aspects of maintenance revolve around proper installation practices and general care to ensure its continued functionality.
One crucial maintenance-related instruction is to ensure correct wiring during installation. The use of an instrument to confirm the live (L) and neutral (N) connections is recommended to prevent electrical issues. This initial step is vital for the thermostat's safe and effective operation and reduces the need for subsequent troubleshooting.
Care should be taken during installation to avoid damaging the wire insulation. Removing too much insulation can lead to short circuits if the bare wire touches the metal mounting wall box. Similarly, when fixing the thermostat with screws, it's important not to let the screws press against or damage the wire insulation, as this also poses a short-circuit risk. Adhering to these guidelines during installation is the primary "maintenance" action to ensure the device's longevity and safety.
Furthermore, if walls are to be painted, it is advised to mount the room thermostat after painting. This prevents dust or paint material from penetrating the thermostat and potentially damaging the Printed Circuit Board (PCB), which could impair its function. This preventive measure helps maintain the internal components in optimal condition.
To ensure accurate temperature sensing, the thermostat should not be covered by objects such as towels. Obstructions can interfere with the thermostat's ability to accurately read the ambient room temperature, leading to inefficient heating control. Keeping the thermostat clear of obstructions is a simple, ongoing "maintenance" practice that users can easily follow.
The thermostat's maximum relay load is specified (3 A resistive or 1 A inductive). Exceeding this limit can damage the relay, leading to device failure. While not a direct maintenance task, understanding and respecting this limit during system design and installation is critical for the thermostat's long-term reliability.
In summary, the BasicPlus2 WT-T is a low-maintenance device, with its reliability heavily dependent on correct initial installation and adherence to basic environmental considerations. Once properly installed and positioned, it requires little ongoing attention beyond setting the desired temperature.
