Page 3: Section 2 - Description
SECTION 2 - Description Heat Interface Units (HIU deliver heat generated from a centralised heating plant to multiple homes, apartments or flats. The method is to combine plate heat exchangers with a control valve to enable the supply of sufficient heat to provide hot water (DHWS) and room heating (HTG). The Hiper HIU has been developed to this concept with unique control and ability to optimise performance and operation. - Page 4 SECTION 2 - Description FEATURES continued Instant Hot Water Response - Instant water response is guaranteed by keeping heat (supplied by the district supply) close at hand to the HIU at all times. At regular intervals (factory set to 20 minutes), the controller opens (factory set to 2 min) the PICV to deliver a low flow of about 100 l/hr, then closes the valve again.
