Every household’s daily hot water consumption profile is different and therefore not
all timer settings could be the same. However, this section may be used as a guideline
that can be followed to enhance energy saving. The assumption made herein is that
no large quantity of hot water will be consumed before 13h00-14h00 and that the
majority of hot water is consumed between 19h00-21h30.
ON 1:
This is used to turn the heat pump
on, and should be set to as late as
possible in the early afternoon i.e. 14h00.
OFF 1:
This is used to turn the heat pump
off and should be set to 1 hour after the
family has gone to bed e.g. 23h00, thus
leaving geyser with hot water ready to be
used for the morning showers etc.
ON 2:
This is used to activate the second
timeslot at which the heat pump should
turn on, and should be set to 1-2 hours
before hot water is to be consumed in
the morning. The heat pump will further
heat the water that may not have been
heated by ON1 and also recover the heat
loss of the geyser during the night.
OFF 2:
This is used to deactivate the
second timeslot and should be set to
heat just enough water for morning
consumption (i.e. two showers). It is best
to let the heat pump deactivate before
consumption starts.
Below are some examples of timer settings to guide the user.
NOTE:
•
The LCD controller will turn off the internal components of the heat pump and
enter into standby mode when the desired set water temperature is reached.
During this time, the water temperature will be monitored and if the temperature
falls below the set temperature (see allowed temperature deviation as set in
Parameter 1) the heat pump will start heating the water again. Thus, it is important
to note that the timer settings allows the heat pump to operate during that
specified interval only.
•
The Enerflow heat pump may heat the geyser faster than an electrical element
in outside air temperatures higher than 18°C, but may take longer when outside
air temperatures are below 18°C. Therefore the timers should allow the heat
pump to reheat the water as long as the conditions outside is favourable.
