Installation: commissioning
1.
Set the DIP switches SW1 and SW2 in the top right corner of the
HP interface board to select the correct heat pump. Labels for
the different heat pump manufacturers are printed on the circuit
board to the left of the DIP switches. Find the correct heat pump
and move the two DIP switch positions to the right of the label to
the (rightmost) ON position.
2.
Ensure the heat pump’s HT zone/DHW water heating is
unscheduled (i.e. always available) otherwise this can cause
schedule conflicts with the Mixergy app.
3.
Ensure that any time constraints on DHW priority are removed.
These can be reinstated once the 0-100% reheat time has been
observed.
4.
Set the Mixergy cylinder default heat source into heat pump
mode. This can be done in the web/phone app or directly on the
cylinder gauge by holding both the boost up and down buttons
and releasing once the display lights blue.
5.
Boost the cylinder and check for correct operation (i.e. a call for
heat is made, circulator pump and heat pump begin running,
cylinder starts to heat.
