for periodic inspection, cleaning or replacement.
Accessories
ThermoSetter codes 116440A(C) and 116450A(C) come standard
without temperature gauge, but temperature gauge, code 116010 can
be field-installed later for confirming the temperature of the hot water in
the circuit.
The temperature gauge dry-well can also be used for inserting a special
immersion probe (with Ø < 10 mm) for remote control of the disinfection
temperature by a dedicated electronic control unit.
Insulation shell
The ThermoSetter thermal balancing valve can be supplied with an
optional insulation shell, code CBN116440 purchased separately, to
minimize heat loss.
