Remeha Avanta Plus

Remeha Avanta Plus
If the DHW water temperature on the OpenTherm ® control can
be adjusted, then the Remeha Avanta Plus will supply water
at the temperature determined on the OpenTherm ® with the
maximum being set in the boiler.
OpenTherm ® is an industry standard modulating control available
from several control manufacturers.
The Remeha Avanta Plus can therefore be controlled directly
by any other controls with this OpenTherm ® logo

2.7.5 Connecting an outside temperature sensor
An outside temperature sensor can be connected to connectors
1 and 2 of the X9 terminal block.
The boiler will regulate the output using the set point of the
internal heat curve.
This can be set as follows:
- Outside temperature minimum set point = -15°C (adjustable
with parameter p29 to between 0 and -30°C)
- Outside temperature maximum set point = 20°C (adjustable
with parameter p28 to between 0 and 40°C)
- Flow temperature set point at maximum outside temperature
= 20°C (adjustable with parameter p27 to between
0 and 60°C)
- Flow temperature set point at minimum outside temperature
= 20°C (adjustable with parameter p1 to between
20 and 85°C)
