Temperature limiter to restrict the maximum temperature of underfloor heating systems

Immersion temperature controller
Part no. 7151 728
May be used as a maximum temperature limiter for underfloor heating
systems.
The temperature limiter is installed into the heating flow and switches
the heating circuit pump OFF if the flow temperature is too high.

Temperature sensor

Immersion temperature sensor for DHW heating as a cylinder tem-
perature sensor (to plug 17 of the extension kit). The contact temper-
ature sensor, which is included as part of the standard delivery of the
extension kit, is used as a return temperature sensor (to plug 2 of the
extension kit).
The sensor well is not included in the standard delivery and must be
ordered separately.
