Setting the heating curve

Connect the outside sensor to terminals 5-6 and connect the "On/Off" type room thermostat or the "Open Therm" type room unit
to terminal 7-8 of the M2 terminal board after having removed the jumper.
Connect the outside sensor to the X13 (Tout/OS) connector on the boiler PCB and connect the room thermostat (RT), the Open
Therm (OT) device or (R-Bus) to the X12 connector after having removed the jumper.
Important
If the heat curve is set via an OpenTherm room unit, do not set the heat curve with these parameters.
The procedure for accessing the settings is the same as that described in the previous paragraph. To set the curve, change the
following settings:
CP000: Heating flow maximum temperature set point.
CP200: room temperature setpoint for zones 5.0 to 30.
CP210: comfort mode climatic curve offset from 15 to 90 (with external probe). Do not change the slope of the curve.
CP230: setting of the slope of the climatic curve from 0.0 to 4.0.
Important
Set the type of outside sensor model used via the AP056 setting

Danger
For low temperature heating installations, modify the CP000
parameter according to the maximum flow temperature.
The factory settings for certain settings may differ based on the
market the product is destined for.
