Installers are also able to check the current status of the XFyre unit parameters by pressing either the LEFT or RIGHT arrow keys during normal operation.

Service Mode

This function is intended to simplify the gas valve adjustment if needed. Manifold gas pressure settings

are listed in Table I on page 16. Automatic modulation does not take place when the controller is in Test Mode, only temperature limitation based on the XFyre Central Heating set point occurs. The user will be allowed to increase or decrease the fan speed by pressing either the UP or DOWN arrow keys.

To activate the service mode, press the UP arrow and ENTER/MENU keys together for 1 second. Once acti- vated, you will see in the display Service and the actual fan speed. The measurement of the combustion levels should always be taken at the highest and low- est fan speed. After 10 minutes, the service mode stops automatically. To exit the service mode, press the UP and DOWN arrow keys together for 1 second.
