Use off-peak / peak hours signal.
Connect the off-peak signal output to terminals 7 and 8 of the boiler.
- The output must be converted into a dry contact, operated according to the logic:
- closed contact = off-peak hours - normal boiler operation
- open contact = peak hours - boiler operation limitation
Use parameter 23 to choose the level of reduction.
- In the parameter setting menu, set parameter 23 to the value:
- 01: ECO setting during peak hours
- 02: FROST setting during peak hours
