Heater priority
• Heater priority: It is decided whether to use the boost heater for DHW operation and the
backup heater for floor heating at the same time by condition.
• Example: If the heater priority is set to 'Main+Boost heater ON', the backup heater and boost
heater are turned on/off according to the control logic. (It can be turned on at the same time)
If Heater Priority is set to 'Boost heater only ON', the backup heater does not operate when the
boost heater operates according to the control logic. (When the boost heater is not in operation,
the backup heater operates according to the logic.)
• In the installer setting list, heater priority category, and press [OK] button to move to the detail
