Water temperature regulation
In a regulation cycle, the system 
first generates water flow 
through the heater housing 
and the plumbing, in order 
to ensure accurate water 
temperature readings as well as 
avoiding heater activation in  
dry conditions. 
The system verifies periodically 
that all parameters are within 
normal range.
Smart Winter Mode 
Our Smart Winter Mode 
protects your system from 
the cold by turning pumps on 
several times a day to prevent 
water from freezing in pipes.
The “Smart Winter Mode”
indicator lights up when the 
Smart Winter Mode is on.
Cooldown
After heating the spa water to 
the desired Set Point, the heater 
is turned off, but its associated 
pump (Pump 1 Low-speed or 
CP) remains on for a certain 
amount of time to ensure 
adequate cooling of the  
heating element, this prolongs 
its useful life. 
The heater icon flashes during 
this time.
If the readings received from 
the system are not valid, blanks 
(- - -) will be displayed until 
normal readings have been 
successfully found. 
After verifying pump activation 
and taking a water temperature 
reading if required, the system 
automatically turns the heater 
on to reach and maintain water 
temperature at Set Point. The 
“Heater” indicator lights up 
when the heater is on. It flashes 
when there is a request for 
more heat but the heater has 
not yet started.
