Assembling the temperature limiter: Steps 1 to 3 in
reverse order
System with heating water buffer cylinder
If the temperature limiter installed to restrict the maxi-
mum temperature of underfloor heating circuit
responds, the heating circuit pump of the relevant
heating circuit is switched off. The heat pump remains
on. The other heating circuits continue to be supplied.
!
Please note
If the temperature limiter installed to restrict the
maximum temperature of underfloor heating cir-
cuit is designed as an
N/O contact
, the heating
circuit pump will not start up.
Design the temperature limiter for restricting the
maximum temperature of underfloor heating cir-
cuit as
N/C contact
.
