Factory setting
If the DHW water temperature on the OpenTherm
®
control can
be adjusted, then the Remeha Avanta Plus will supply water at
the temperature determined at the OpenTherm
®
with the maxi-
mum being set in the boiler.
OpenTherm
®
is an industry standard modulating control avail-
able from several control manufacturers.
z
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
LT.AL.W7H.000.029
An outside temperature sensor can be connected to connec-
tors 1 and 2 of the X9 terminal strip.
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 tempera-
ture = 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)
LT.AL.W7H.000.030

An outside sensor used in conjunction with a simple 230 V
time clock will provide easy to set up and operate - timed
weather compensation heating based on the above graph.
