confiGuration Menu
The Steffes Comfort Plus Hydronic heating system has a Configuration Menu,
which allows the system to be customized to the power company and consumer’s
needs. This menu can be accessed on start-up and allows configuration settings
to be easily adjusted.
To access the Configuration Menu:
Step 1 Energize the system. Access to the Configuration Menu is allowed
for the first two (2) minutes of operation. If the system has been
energized for more than two (2) minutes, the 15 amp circuit
breaker must be powered off and back on to gain access to this menu.
Step 2 Press and release the M button until the faceplate displays “CONF”.
Step 3 Press the up arrow once and the faceplate will display “C000”. The faceplate will flash between “C000”
and the corresponding configuration value.
Step 4 If necessary, edit the configuration value by pressing and holding the M button while using the up or the
down arrow button to change the value.
Step 5 Once the value is correct, release the buttons and press the up arrow button to go to the next
configuration (C001,C002, etc.)
Step 6 Repeat steps 4 through 5 until all configuration settings have been adjusted to the desired values.
Step 7 Once configured, use the down arrow to leave the Configuration Menu.
In most applications only a few, if any, configuration changes will be necessary. Following is a description of the
configuration settings and their function:
