heating_channel_linear

The linear calculation in heating_channel_linear.yaml.

It take the (target temperature)- (real temperature) and map it from 0=full closed to 1=full open

"round(((((id(${ch1_thermostat_name}_thermostat).target_temperature_high + id(${ch1_thermostat_name}_thermostat).target_temperature_low)/2 - id(${ch1_thermostat_name}_thermostat).current_temperature)+1)/2)/0.1)*0.1;"
