Maintenance
Both the adjustable balancing cartridge and the disinfection control
cartridge can be removed from the valve body for periodic inspection,
cleaning or replacement.
Accessories
ThermoSetter™ codes 116140A and 116150A 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 CBN116140 purchased separately, to
minimize heat loss.
