Load situation two: two single-phase resistive loads, such as two
immersion heaters for each water heater.
⚫ Three-phase power input, a single-phase L1 adjustable power output
mode and a singlephase L2 fixed power output mode. Two PT1000
temperature sensors for loads of each phase.

Load situation three: three single-phase resistive loads, such as one
immersion heater for water heater and two heating spaces.
⚫ Three-phase power input, a single-phase L1 adjustable power output
mode and two single-phase fixed power output mode(L2/L3). Three
PT1000 temperature sensors for loads of each phase.
