5.0 Domestic Hot Water If not using DHW, change parameter P63 to 0 and disregard the following To meet requirements set in MBIE NZBC, clause G12 stored DHW must be heated to 60°C once a day, or 60°C for the period of one hour once a week, for protection against Legionella. -
Page 12: High Flow Temperatures And Underfloor
6.0 High Flow Temperatures and Underfloor With underfloor installations it is important that high flow temperature ie. >50°C are not introduce to the floor. High temperatures can cause damage to certain construction materials as well as being uncomfortable. Please fit the supplied sticker to the bezel/surround of the heat pump controller to advise users of hazards when increasing the setpoint. -
Page 13: Resetting Errors
7.0 Resetting Errors To reset errors, the heat pump power supply must be cycled off and on at the isolation switch. At the point of commissioning a common error is E15 (Insufficient water flow) this is likely caused by air still being present in the system or installation debris blocking the filter ball valve.
