How final set point is calculated
Equitherm curve returns temperature of flow water based on outdoor temperature. Angle of the curve, parallel shift, temperature limits and adjustments based on data from thermostats are affecting the final results.
Angle
For floor heating systems, values between 0.2 and 0.8 are commonly used. Lower values are more suitable for high quality insulation.
