Menu C08: Setting the slope of zone 2
Authorisation to change the slope
Slope 1,6
of network 2 (zone 2)
Slope 1,4
Default setting: C08=0 and the slope set is 1.0.
Slope 1,2
Slope 1
Slope 0,8
Example:
Direct radiator network feed temperature: 70°C
Slope 0,6
Determine the temperature drop (Δt) between the network feed and return
Slope 0,4
in accordance with the installation characteristics: e.g. 20°C
In this example, the return temperature is estimated to be 50°C.
Slope 0,2
On the corresponding axes, note down the maximum return temperature for
network 2 and the minimum outdoor base temperature (e.g. -6°C).
In this example, the correct slope is 1.
Manual setting: Set the temperature to 20°C on the DELTA 200 and set
the thermostatically controlled valves to maximum. For outdoor temperatu-
res of around 10°C, you must obtain 20°C in the room measured.
Use a higher slope if the temperature is lower.
Use a lower slope if the temperature is higher.
Return the thermostatically controlled valves to the desired setting.
