The ZW 05 DCU microprocessor-driven charge control has 2 separate control signal outputs.
The charge controllers for underfloor storage heating AR 05DCU or storage heaters can be connected to the Z1+, Z2- terminals (0.91 ... 1.43V). Charge controllers for underfloor
storage heaters with control signal -2.85 ... -3.6 V (e.g. Type AR 1741 ... AR 1744, RFV 351 DC ... RFV 354 DC) to terminals I1, I2 .
