When ‘’1 Temperature’’ is selected, screen shows hydraulic crossover with 1 temperature.
If
‘’2 Temperatures’’ is
selected, screen shows accumulation tank with 2 temperatures.
This option can be changed only by authorized serviceman.

Configuration
CRO / BUF
Version 1: (display shows 1 temperature, eg. hidraulic crossover)
Version 2: (Display shows 2 temperatures (eg. accumulation tank)
1 - Boiler PelTec / PelTec-lambda
2 - Air self-venting group 2,5 bar
3 - Motor 4-ways mixing valve
4 - Closed type expansion vessel
5 - Return flow temperature sensor
6a - Hydraulic crossover
6b - Accumulation tank
7 - Accumulation tank sensor 1 (upper)
8 - Accumulation tank sensor 2 (lower)
9 - Hydraulic crossover sensor
Connecting the temp. sensor 9 (version 1) and temp. sensors 7, 8 (version 2) is not required for operation of the boiler.
These temperatures are only informative, only to see the temperatures and they don't affect boiler operation. If temp.
sensors are not connected, regulation will show temperature " - °C". The boiler regulation will not report any error even if
the sensors are or defective.
