• The default setting for FSV (#5041) is value 0 (No, no application of the Power Peak Control).
• If FSV(#5041) setting "1", compressor, backup heater, booster heater operate according the below table:

• The default input type is a high signal (voltage applied).
• In exceptional situations it is required to change to low input, depending on the demands of the (local) power
• When the input signal is applied, the system goes into "Thermo off" for all operations (as indicated by FSV (#5042)).
• If the EHS system is not operable for a long time (>60min) by applying the Power Peak Control, the usage of glycol is
advised during subzero ambient conditions. Please check the terms and conditions of the (local) power company.
