The IPHT has been designed to either be retro-fitted to existingPoints Heating Sites orfor new installations to reduce the Installation costs (on new sites) as well as the power required to operate a points heating site.With the IPHT there is no need for a new control cubicle as all the controls and communications are taken care of by the IPHT. This will obviously offer significant budget savings in both Installation and power rates which, are usually charged to individual zones. Nothing on the main system will be affected or will need to be modified; all that is necessary is to attach the smart box to the transformer and connect one of the main cables from the transformer to the smart box.
