Comfort
Control
The Comfort Level is an easily adjustable user control that allows the
efficiency vs guaranteed hot water storage balance of the system to be
managed. The control is easy to adjust and can be altered at anytime to suit
changing circumstances, weather, guests in house and such.
The + and – buttons on the front panel will by default adjust the
‘comfort level’ and the 7 segment display will indicate what the comfort %
setting is after each update. There are also optional external devices which
can adjust this value in addition to the front panel of the controller.
The Comfort Control manages the electric boost heating only.
Set higher for more guaranteed hot water
Set lower for more savings
This control was included as a solution to the problem that different users
have different hot water usage vs savings expectations.
The Comfort Level percentage is not a direct temperature control; rather it
uses sophisticated computer logic to determine the best temperatures and
which sensors or elements in conjunction with the selected HWC profile to
realise an optimised system for the user’s expectations of stored hot water.
At first it might be best to start with a maximum or high setting and gradually
reduce over some time (maybe days) until the best balance is found.
Comfort set to 0% = Holiday mode and the tank will not heat with the electric
elements except if BioSafe sterilisation is required.
Note: The last Comfort setting is written to permanent memory 5 minutes
after the last adjustment. If power is removed before the 5 minutes has
elapsed the setting will revert to the previous stored value.
