Additional functions
The Smart Grid (SG) function allows the power supply utility (PSU) to optimally
adjust grid utilisation through intelligent control of consumers.
Using external switching commands (floating contacts SG_0 and SG_1 on
terminals X1 – 9/10 and X1 – 11/12), the compressor and/or electric heater
operation can be blocked, or requested with/without an increase in the set heating/
DHW temperatures, or the active cooling function enabled.
The heat pump can be operated using a compressor, electric heater, or both a
compressor and electric heater.
The SG function status message is shown on the status pages of the BM-2
programming unit and in the "Displays"/"Heating appliance" submenu on the
AM display module and BM-2 programming unit.
The SG function for heating is only possible in system configurations with header
return temperature sensor SAF (T_headerRTN) and where the outside temperature
is below the set winter/summer changeover.
For active cooling by the SG function, active cooling must be enabled in the AM/
BM-2 standard settings, as well as in contractor parameters WP058 and WP033.
In addition, the outside temperature must be above the set winter/summer
changeover and the enable temperature for active cooling (WP053).
If standby mode is set on the BM2 programming unit, the SG function is not
available.
