Weather Compensation Curve.
If a 0-10 volt signal is the required heat generation control
method for the RVA33 / boiler installation this setting must be
adjusted to -- on all RVA47s present in the boiler cascade
installation. This will result in the Auto, On/Off and Frost lights
becoming inactive. Alteration to parameter #170 and #172 will
also be required.
