in.xe Power-up & breaker setting
Valuable Tips
Make sure that all valves are open in the spa plumbing and that you
have a good water flow circulating from the primary pump
into the heater.
Important: a minimum flow rate of 18 gpm is required.
Technical stuff
There is no mechanical switch in the in.xe heater. Instead in.xe
systems have integrated in.flo technology. The in.flo is an all
electronic dry-fire protection device built-in in.xe's heater.
At power up, in.flo performs a flow check through the following
process:
Pump 1 starts for 2 min. The display will show "_ _ " during the check
flow process. After 2 mins, the system validates proper water flow.
In case of failure, the systems tries again.
The water temperature is shown on the keypad display.
Once the water has reached the set point value plus 0.8 degrees ˚F
the heater is turned off.
