Explanation
211.2
Secondary pump
Connection values
■ Max. output: 130 W
■ Voltage: 230 V~
■ Max. switching current: 4(2) A
Connected at the factory.
■ In systems without a heating water buf-
fer cylinder, no other heating circuit
pump is required (see terminal 212.2).
■ On site, connect the temperature limiter
to restrict the maximum temperature of
underfloor heating circuit in series (see
page 48).

Connection values
■ Max. output: 130 W
■ Voltage: 230 V~
■ Max. switching current: 4(2) A
3-way diverter valve connected at the fac-
tory; on site, connect the cylinder primary
pump in parallel.
In conjunction with the pri-
mary store system:
■ Cylinder primary pump
