Electronically controlled Heat Interface Unit. With auto fault diagnosis and prepayment switching. Available with remote monitoring.
Indirect interface for instantaneous DHW and space heating.
HIPER II is an electronically controlled heat interface unit.
The electronics provide automatic fault diagnostics and also error warnings when the supply to the HIU is not suitable for efficient operation. These can be read on the screen, or when linked with the a remote monitoring device, can be read externally. Multiple parameters are adjustable to enable the commissioning engineers to adapt the operation of the HIU to suit the operating conditions of the heat network it is installed in. A temperature controlled keep warm function can be used or turned off if the installation does not require. To protect the pump during long summer periods where heating is not required can be programmed to run the pump for minutes to prevent sticking and formation of chemical residue on moving parts.
