Terminals
Function
Explanation
211.2
Secondary pump
Connection values
■ Max. output: 130 W
■ Voltage: 230 V~
■ Max. switching current: 4(2) A
■ In systems without a heating water buf-
fer cylinder, no other heating circuit
pump is required (see terminal 212.2).
■ Connect the temperature limiter to re-
strict the maximum temperature for un-
derfloor heating systems in series (see
page 31).
Secondary pump connected at the facto-
ry; the temperature limiter must be con-
nected on site.
211.4
M
r
3-way diverter valve for
"Central heating/DHW
heating"
Connection values
■ Max. output: 130 W
■ Voltage: 230 V~
■ Max. switching current: 4(2) A
3-way diverter valve connected at the fac-
tory; connect the cylinder primary pump
on site in parallel.
In conjunction with the pri-
mary store system:
■ Cylinder primary pump
M
■ 2-way shut-off valve
Internal unit: Controller and sensor PCB (sensors)
Set the required parameters during com-
missioning; see from page 68.
