Temp Settings / WIFI connection

There are also a range of secondary settings which can be adjusted to suit your Primal experience. If you hold down the set button for 3 seconds it will bring up a screen displaying P1. You can filter through P1 to P5 using the up and down arrows. To adjust each parameter click the set button when the P1 is displayed on the screen to go into that specific parameter where you can then use the up and down arrows to adjust it.

Meaning of each parameter:

P1 - Temperature difference, this setting allows you to adjust the temperature difference of the chiller when it turns back on. For example if you set the target temperature at 3c (37f) and P1 to 2 degrees. The chiller will turn off at 3c (37f) and turn back on at 5c (41f) as there is a temperature difference of 2c.

P2 - Is a start up delay for the compressor. We recommend leaving this at 3 minutes to prevent damage to the other components.

P3 - Is a calibration setting and is only used if the water temperature does not match the temperature shown on the screen of the chiller. Leave this at 0 unless required.

P4 - Is to change between Fahrenheit and Celsius.

P5 - Is to turn on WIFI connectivity for the TUYA Smart App.
