• oTc climate curve - cH1 (zone 1 cH)
The graph in Fig. 11 is made by the outside temperatures for minimum CH (+18 °C) with the Zone 1 minimum CH setpoint (+20 °C) and
the outside temperatures for maximum CH (-10 °C) with the maximum Zone 1 CH setpoint (+85 °C).
The 'Offset Zone 1' parameter decreases or increases the setpoint calculated via the line of the climate curve shown in the graph in Fig. 11,
but the setpoint is still limited by the 'Zone 1 CH Setpoint' and 'Zone 1 minimum CH Setpoint' parameters.
The values indicated are default values and can be changed via the relevant parameters.
The 'Zone 1 maximum CH setpoint' parameter acts as a limit for the 'Zone 1 CH setpoint' parameter.
• oTc climate curve - cH2 (zone 2 cH)
The graph in Fig. 12 is made by comparing the outside temperatures for minimum CH (+18 °C) with the Zone 2 minimum CH setpoint
(+20 °C) and the outside temperatures for maximum CH (-10 °C) with the Zone 2 CH setpoint (+35 °C).
The Zone 2 offset parameter decreases or increases the setpoint calculated via the line of the climate curve shown in the graph in Fig. 12,
but the setpoint is still limited by the Zone 2 CH setpoint and Zone 2 minimum CH setpoint parameters.
The values indicated are default values and can be changed via the relevant parameters.
The Zone 2 maximum CH setpoint parameter acts as a limit for the Zone 2 CH setpoint parameter.
