Here's the procedure for setting the display:

• Disconnect the heater from its power source
• Hold both the 'up' and 'down' buttons on the thermostat as you reconnect the power
• The screen will light up and display the current display setting: GC = gas centigrade, GF = gas Fahrenheit
• Release the two buttons and immediately start pressing the 'up' arrow to scroll through the display options.
• Select GF for Fahrenheit or GC for Celcius
• Wait two seconds, and the thermostat will store the selected display preference
• Now relax and enjoy reading the ambient temperature without doing the math!
