Auxiliary heat

The auxiliary heater is made up of an electric heating element on the supply pipe that has
three outputs, ADD.HEAT 1, ADD.HEAT 2 and ADD.HEAT 3, and can be controlled in five steps:
• Step 1 = ADD.HEAT 1 = 3 kW
• Step 2 = ADD.HEAT 2 = 6 kW
• Step 3 = ADD.HEAT 1 + ADD.HEAT 2 = 9 kW
• Step 4 = ADD.HEAT 2 + ADD.HEAT 3 = 12 kW
• Step 5 = ADD.HEAT 1 + ADD.HEAT 2 + ADD.HEAT 3 = 15 kW
To calculate the total energy consumption, see the "Settings- Calculating energy consump-
tion" section.
In the event of an alarm, the auxiliary heater engages automatically.
