Abbr.

Meaning

- When using fault current circuit breakers,

observe separate neutral leads for normal
and special tariff!

- Observe identical phase potential of the

control circuits for normal and special tariff!

- The individual relay outputs of the heating

controller withstand a max. load of 4 A (at
cos Phi>0.6).

- Max. total current for terminals: 6 A.
- This must be considered when choosing the

circulating pumps. Use contactors if
necessary.
