Table 20. Operating mode
Attempt to record a number beyond the allowable values leads to an error message. The variable is stored in
backed-up EEPROM memory.
MB_ADDR_FAN_SPEED – depending on operating condition (see
MB_ADDR_ZONE_MODE):
•
For „heating I” and „heating II” mode – variable that determines a fan rotation, that will be set in
case of setting the heater through two-state algorithm
•
For “air supply” mode – a variable that determines a current fan rotation.
Allowable values for the variable fall within a range from 0 to 3. The variable is stored in backed-up
EEPROM memory.
