Heat Meter If provided the booklet is attached to these instructions. Cold Water Meter If provided the booklet is attached to these instructions. System Safety Relief Valve It is assumed that there are system safety valves in place to take care of this so no pressure relief is provided within the unit, although please note that maximum pressure is 6 bar. - Page 11 If the Nordgas “Easyremote” is fitted then always first check if any error messages appear on the display [see Figure 7 above]. Check also the fault light on the electronic box [see Appendix 3]. If there are no error messages or fault lights, then firstly switch off power to the unit, wait for 10 seconds and then re-start the unit as this will reset the stepper motors.
- Page 12 No Hot Water or Heating Control Valve not Check that 24V is being operating or Diverter supplied to either or both Valve no operating DC coils. If above does not resolve issue, replace relevant stepper motor Pump not operating Check that impeller has not seized.
- Page 13 SERVICING SCHEDULE Note – when working with the unit, supply services when connected could reach 85°C, and once electrically connected the unit has 230V present within. It is recommended that the unit is serviced once every 12 months to maintain its efficiency and longevity.
