2 imensions C C A B B A E Introduction The heat interface unit is the latest intelligent range of HIU from Altecnic. The is the complete solution for instantaneous hot water production and space heating control. esign The twin plate design hydraulically separates both domestic and space heating from the central primary supply. The internal electronic control unit ensures maximum efficiency and control but also incorporates other additional important features. The standard unit can be set to hold a stable heating flow temperature, to suit the installation (radiators, UH for example), but crucially, can also be set to vary the heating flow temperature automatically depending on the temperature of the heating return water. This allows the unit to automatically compensate for changes due to external influences, such as outside temperature etc. thereby ensuring that the unit and the system operate at maximum efficiency The unit also features a pump bypass to protect the pump, in case of complete radiator TRV shutdown. The is extremely compact in design and lightweight, benefitting both installers and architects. The unit has a fully insulated front cover, manufactured from expanded PPE, which includes a sliding window to allow the tenant to access the integral heat meter (if installed). The unit can be fitted with an optional isolation module which allows the domestic hot water (HW) and heating circuits to be remotely isolated by the building owner/landlord etc. via a computer with internet access.
