Overview
In the mixed operation of electric hot water and electric storage
heaters, the priority switch interrupts the charging procedure of
the storage heater if hot water is required during the low-tariff
time, thus limiting the connected load in compliance with BTO § 6.
The control circuit terminals must be sealable.
■
Benefits
Reduction of the connection fee, which depends on the maximum
load to be supplied (BTO, German Federal Regulation on Tariffs
§ 6 Section 4), when used in systems with continuous-flow heaters
and electric storage heaters where the continuous-flow heaters
are switched with priority.
