W1290 Thermostat Low limit (P3) setting problem

[fahad.official]

In my Thermostat w1290 I faced a issue that when I tried to set P0-P6 the P3 value (Lower limit value) didn't exceed 14°C but in YouTube videos they can change the value upto 33°C is this a problem to my Thermostat?! Is any solution to it....!!!!!

Some versions of the W1290 thermostat come with firmware restrictions that limit the temperature range.
