UK: Toshiba’s new Black Pear air conditioning controller boasts a range of inbuilt modes that can be selected to match particular applications.

As well as providing end users with new ways of saving on running costs, it offers a comprehensive set of control and monitoring functions.

The RBC-TSI1 Black Pear includes modes to allow integration with higher level building management systems via voltage and resistance, with discrete inputs on Modbus, and special modes for use in multi-occupied buildings.

The Hotel Mode gives end users a pre-set setback option, which can be integrated with a key card window switch. This is said to minimise energy use while delivering optimum cooling and heating to the room.

There are also two Eco modes, one based on a timed fan operation, enabling the unit to run in an operating mode for a pre-determined period of time; the other allows the use of two set points, to cover heating and cooling.

Suitable for application with Toshiba VRF, light commercial splits systems, and VN ventilation systems, the RBC-TSI1 features: direct connection to TCC-NET 2-wire A/B network; six analogue inputs selectable as voltage or resistance; run/error indication; RS-485 connection; monitoring and control via serial Modbus; Modbus address range 1 to 254; up to 16 units can be operated in a Master/Follower configuration; up to eight units on a single link, providing detailed information on each unit.

Fraser Hymas, head of control systems at Toshiba who lead the development, said: “The new Black Pear packs a lot of capabilities and options into a small package. We believe its pre-set energy saving modes will be highly attractive to hotels, in particular, where sporadic occupancy – both during the day and day-to-day – presents significant opportunities for energy saving.”

He added: “For contractors, the fact that it can be used pretty much across our product range means that, once they are familiar with the system and the simple set-up steps, they can apply with confidence to most installations and get the benefits of ease-of-use, flexibility and energy savings for customers.”
