What is Rada Sense?
Featuring first-of-its-kind digital technology, Rada Sense offers a smarter, safer and more hygienic solution of delivering warm water to users.
Key components of Rada Sense include a no-touch control panel, a digital mixing valve (DMV), and the ability to fully programme showers and basins in your washroom.
A key component of Rada Sense is the T-LogicTM digital intelligence system, which enables your staff to set up, manage and monitor washroom water to outlets such as basins and showers.
T-LogicTM ensures easy programming and control of water temperature, flow times and thermal disinfection via a handheld PDA, as well as providing intelligent fault diagnosis, usage information and service data.
This product is designed to help you manage water safely and to reduce maintenance costs and downtime in your washroom.

What is a mixing valve? What does it do?
A mixing valve blends cold and hot water supplies to deliver safe, tempered water to your basins and showers at pre-set temperature range.
Rada Sense incorporates a first of its kind digital mixing valve, which offers enhanced, performance, security and ease of maintenance.

What is the difference between a thermostatic mixing valve and a digital one?
A thermostatic mixing valve (TMV) and digital mixing valve (DMV) both blend hot and cold water to supply a safe warm water temperature. The TMV uses a thermostat to detect changing warm water temperature and in turn then adjusts a mechanism to change the ratio of hot and cold water being blended to maintain the required set temperature.
A digital mixing valve differs in that it uses thermisters (temperature probes) to detect the temperature of the outlet warm water. It maintains this temperature via the T-LogicTM circuit to instigate the operation of an electrical stepper motor which in turn adjusts a mechanism to control the ratio of hot and cold water being blended.
Where Rada Sense offers an distinct advantage to maintenance staff is in the constant monitoring by T-LogicTM. This enables intelligent fault finding and the ability to programme Rada Sense for tasks such as duty flushing and thermal disinfection with minimal downtime.

Where can I use Rada Sense?
Rada Sense can be used in many situations, particularly hospitals, nursing homes, schools, leisure centres and commercial washrooms where there is high volume traffic. The system offers an elegance that is at home in high-end bathrooms and a reliable performance that will provide hygienic, safely tempered water to areas where water and energy savings are required.

What outlets can I manage with Rada Sense?
Rada Sense is designed for use with showers and hand basins for commercial washrooms.

How do I programme it?
Rada Sense can be programmed entirely from a handheld PDA. Simply load the Rada Sense software onto your PDA to update flow times, maximum, minimum and default water temperatures. You can also set up the duty flush cycle to ensure that the system is regularly flushed. A thermal disinfection flush can be programmed as and when required.

How can Rada Sense save me water?
Rada Sense can be fully programmed for flow duration and features automatic-shut off. The Rada Sense DMV for basins is supplied with low flow regulators. The Rada Sense DMV for showers can be supplied with a 9 L/min Rada VR 105 shower head or a 6 L/min Rada VR 106 shower head. These features are designed to save water in a variety of applications.

What happens if there is a black out?
Rada Sense relies on the use of 12 V DC power, which is supplied via a 240 V AC to 12 V DC adaptor. If there is a blackout the digital mixing valve will not operate. However, within the Rada Sense assembly there is a solenoid valve, which controls the flow of water. In the event of a power failure the solenoid valve will shut off water flow and the digital mixing valve will shutdown to safeguard users from injury and ensure that water does not get wasted.

What happens if the cold water fails?
If the cold water fails, the solenoid valve within the Rada Sense shuts to prevent any water flowing from the outlet to ensure that users are not at risk from scalds.
This ensures that users are kept safe at all times when using your washroom.

How does the thermal disinfection work in Rada Sense?
Thermal disinfection is important for any warm water system, to prevent the growth of Legionella. Rada Sense is designed to make the process simpler, and thermal disinfection is carried out by disabling the Rada Sense with a magnetic key, then using the PDA to arm the disinfection process.
Once the Rada Sense is armed, you may start the disinfection via your PDA, which will start the cycle. The system is then flushed with water at a temperature exceeding 60°C, and the result logged on your PDA. The Rada Sense can then be enabled again by using the magnetic key.

What about duty flushing?
Rada Sense can be programmed to operate a duty flush periodically when an outlet has not been used for a period of time. This minimises the growth of water-borne bacteria in stagnant water that is retained in a pipework dead-leg.
The default setting for duty flush cycle is 2 minutes every 12 hours. These settings can both be adjusted within a range of 1-59 minutes for the flush cycle, and from 1 to 1000 hours for the waiting period.
