Hopefully the temperature will be set correctly and all you need to use the controls for is to adjust the pump speed and the night time lights.
Setting temperature: Press and hold the up and down arrows until it shows "STMP" then use up and down arrows to set to 38 degrees which is ideal. Don't set any higher! Press OK when ready.
Current temperature: Press the up and down arrows until it shows "WTMP" to see what the actual water temperature is currently.
Use the "pump" button (5) to adjust pump speed: AUTO / LOW / HIGH / OFF
Button (4) gives control of the coloured lights for evening use.
Button (6) doesnt operate anything.
If the icon (8) is glowing red then the heater is running.
When you are finished using the hot tub, please press the "pump" button (5) to adjust pump speed down to "AUTO". This will keep the heater and filter running, but saves power by turning off the jets. If you forget to do this, it will switch to AUTO after a short period.
If you accidentally set the pump to "OFF" then the heater may not function at all, and the tub could cool down significantly over several hours. Make sure it's always on AUTO when not in use.
Each jet can be turned off by turning the outer chrome colour ring anti-clockwise
The "AIR" selector introduces air into the water jets when it's turned on
The diverter valve sends the water to either all the jets, or to focus all the water on the single larger jet in the deeper seat. The valve can be stiff to rotate.
