Operating modes
The operating mode can be changed through the spa user interface.
Six different operating modes are available:
1) Eco Heat (EcoH)
2) Smart Heat (HEAT)
3) Cool (COOL)
4) Eco Auto (AUTO)
5) Smart Auto (SMRT)
6) Electric (ELEC)
Eco Heat (EcoH)
In this mode, the in.temp is used as the unique source of
heating. The heating element is kept off and the in.temp
is not used to cool the water should its temperature rise
above the current set point.
Smart Heat (HEAT)
This mode uses the in.temp as the main heating source.
The heating element is turned on only if there is a large
temperature difference between the water and the set
point or if the ambient temperature gets too low. The
in.temp is not used to cool the water in this mode.
Cool (COOL)
This mode uses the in.temp in cooling mode only.
The in.temp is not used as a heating source and the
heating element is never activated.
Eco Auto (AUTO)
This mode borrows functionality from both Eco Heat
and Cool modes and has the ability to select the proper
Heat or Cool mode automatically according to the water
temperature. The heating element is never activated in
this mode.
Smart Auto (SMRT)
This mode borrows functionality from both Smart Heat
and Cool modes and has the ability to select the proper
Heat or Cool mode automatically according to the water
temperature. The heating element is activated only if there
is a large temperature difference between the water and
the set point or if the ambient temperature gets too low.
Electric (ELEC)
This mode keeps the heat pump off and uses only the
heating element to regulate water temperature.
Freeze Protection
In cold weather, if it becomes impossible for the in.temp to keep the water temperature above freezing point, the help of
the heating element might be required even if its use should be prohibited by the operating mode or conditions.
At any time, if the water temperature drops too close to the freezing point, the operating mode will be switched
temporarily to “Smart Heat” and the system will heat until the minimum allowed set point has been reached before
reverting to its previous operating mode and resume normal operation.
Three minutes waiting time
In any circumstances, when the in.temp is shut down, please be aware that there is forced waiting time of three minutes
before the in.temp can operate again. This is so to prevent damage to the equipment. For example, if the operating
mode has been changed from Cold to Hot succeeding an increase of the setpoint, the in.temp will be allowed to start
only after a delay of three minutes.
