Secondary pump
■ In systems without a heating water
buffer cylinder, no other heating circuit
pump is required (see terminal 212.2).
■ Connect the temperature limiter in ser-
ies as maximum temperature limiter
for underfloor heating circuit (if instal-
led).
Connection values
■ Output: 130 W
■ Voltage: 230 V~
■ Max. switching current: 4(2) A
Secondary pump connected at the fac-
tory; the temperature limiter must be
connected on site.
