Your new Daikin Altherma
      air source heat pump system

      In this manual you will find information and
      guidelines that will allow you to run your
      Daikin Altherma heat pump system in the
      most energy efficient and cost effective way.
      We hope you enjoy a warm and comfortable
      winter season!
      System overview
      The heart of your new central heating system is a highly efficient
      Daikin Altherma air source heat pump. The heat pump heats the water
      which flows around your heating system, and separately heats the hot
      water cylinder when required.
      The central heating is controlled from the room thermostats which
      switch on the heat pump when heating is required, sending warm
      water through the underfloor pipes and radiators.
      Most rooms will have their own
      thermostat that controls the
      room temperature.

Your checklist for diagnosing
      possible faults
      1. Is the thermostat set too low?
      Check that the temperature on the thermostats in the rooms is
      set high enough to start the heating. Remember – set this to a
      comfortable level and not maximum.
      2. Is the mains power switched off?
      Check that the power is switched ON. Check the fuse box and isolator
      switches next to both the indoor and outdoor unit.
      If you have checked points 1 and 2, and the system still fails to
      operate normally, then;
      3. Manually reset the system
      Turn off the power. Wait 60 seconds then turn it back on.
      If this does not work, then;
      4. Check the system pressure
      The small pressure gauge inside the hydrobox should read between
      1 bar and 2.5 bar. If the system pressure is outside of this range then
      please contact the service and maintenance company for advice.
      If the system still does not operate as normal, then;
      5. Check the controller
      This located on or near the hydrobox. If the red LED is flashing, the
      unit has a fault. Check for a fault code (typically a number and a
      letter, e.g. 7H) and then contact the service / maintenance company,
      telling them the fault code which is displayed.
