As well as the reduced operating costs associated with greater energy efficiency, the Blue e cooling units also have the following benefits over the Basic variant. Larger enclosure internal temperature setpoint range, with a lower limit of 20°C; visualisation of enclosure internal temperature and error messages on a 7-segment display; up to 10 units may be connected in a master/slave configuration; switching hysteresis is adjustable in the range 2-10°C; parameters are easily adjusted using the exposed buttons, however passcode protection restricts access and prevents accidental adjustment of parameters; improved monitoring, including high condensate level and dirty filter mat warnings; setting up and interrogation possible using the RiDiag II diagnostic software and may be incorporated into higher-level remote monitoring systems.
A decision has been made to phase out the less efficient cooling units with Basic controller by 31 December 2012.
