Operating Instructions XWA11V 1598003200 14. PARAMETER LIST Ot Thermostat probe calibration: (-12.0÷12.0°C/ -21÷21°F) allows to adjust possible offset of the thermostat probe. CF T measurement unit: °C = Celsius; °F = Fahrenheit. When the measurement unit is changed the Set Point and the values of some parameters have to be modified. rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows decimal point display. Ut Display update: The time delay of the T readout (0÷255s) on
