I have 3x Multiplus 5000 with Cerbo GX.
On phase3 i have connected boiler 2,4kW on AC2 which starts when SOC is above 97%.
I have connected also Whirlpool 2,4kW on phase3 but I want to disable boiler when Whirlpool is running to avoid taking energy from grid.
Is there any functionality, which can stop AC2 (boiler) when there is load more then 500W on the phase3 ?
You can use the Relay Assistant to turn the AC2-Out relay on and off based on AC power consumption.
Best to have some hysteresis to avoid it chattering, so have the off threshold significantly higher than the on threshold.
Can you give me please screenshot how it should be setup?
Then set Relay On, AC Load, skip Extra Drive Option, set power level.
Repeat with a second Assistant for Relay Off.
I have setup assistant according below images - summary of assistant.
Watter boiler takes 2200W and is connected to AC Out 2
On same phase (but not on AC Out 2) is connected also Whirpool which takes 2200W.
When I start Whirpool, boiler is flapping - on/off/on/off each second.
How to avoid the flapping as the boiler can be damaged during the flapping.
