4. Installation information
Incorrect size selection and / or temperature setting of the valve could cause danger of
pollution and Legionella in the plumbing installation.
The BOSSTM 205 TBV must be installed in correct flow direction. The flow direction is
indicated by an arrow on the body of the valve. It can be installed in any orientation.
The valve has EN10226 BSPT threads.
To avoid malfunction, avoid dirt or debris entering the valve.
Install valves using a 27mm (for DN15) or 32mm (for DN20) spanner.
To prevent imposing strain on the valve joints, pipe work and valves must be adequately
supported.

5. Adjustment of set-point temperature
The factory setting of the valve is 58°C.
If the pre-setting needs to be changed:
Loosen the M5 screw with an allen key (size: 2.5)
Turn the black cap until the desired setting is indicated above the white arrow.
Fix the position by tightening the M5 screw carefully with an allen key (size: 2.5).
6. Thermal disinfection
The valve is suitable for thermal disinfection at temperatures greater than 70°C.
When the temperature rises to greater than 70°C, the valve automatically reaches the thermal
disinfection regulating range.
If the temperature drops below 70°C again, it is back in normal operation.
