What Does the Jandy JXIQ400PK JXiQ 400K BTU Propane Heater Do?
This Jandy JXIQ400PK has innovative VersaFlo Integrated Bypass technology. Which helps the heater provide energy up to 84% efficiency. This heater also provides owners with a heat-up time estimate status on the largest display in the industry. Also, can use this feature with the iAquaLink app, which needs Jandy AquaLink automation.
Furthermore, it has a compact cabinet construction and is designed to keep rodents out. It also helps installers and homeowners because the heater senses its supplied voltage with the Auto-sensing power input. Another, great feature is its one-of-a-kind low gas pressure switch that blocks ignition if there is a problem with the gas line.
This heater is even equiped with extra sensors that give it self-diagnostics. This helps homeowners and service technicians find problems quickly by connecting to the aqua link app via blue tooth. There is even a sacrificial anode that pulls out corrosive elements in the water protecting heater parts.
*If ordering the 200K model it requires vents at 6 inches. The 400k model needs 8 inches, so check the vent run first.*

Gas pool and spa heater
Heats only when it needs to
VersaFlo, Jandy's integrated bypass, sends water through the heat exchanger only when the pool is calling for heat.
The controller also works out how long it will take to reach your setpoint and shows the estimate on screen.
Gas pool and spa heater
Sensors that guard the heater
A low gas pressure sensor keeps the burner from lighting when the supply runs short. The heater also compares inlet and outlet water temperature to check flow, which helps avoid heat exchanger failures.
A sacrificial anode pulls corrosive elements in the water away from nearby parts. Salt pools are harder on equipment, and the anode is there for that.
