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.

doc_tap_EqCurveReturn;

Angle

doc_tap_Angleee;

For floor heating systems, values between 0.2 and 0.8 are commonly used. Lower values are more suitable for high quality insulation.

Table below shows resulting set point temperature based on outdoor temperature and angle of the curve:

E.g. if outdoor temperature is 0ºC and angle of equithermic curve is 0.6, resulting set point temperature is 37ºC.

doc_tap_outdoor_37ºC;

Parallel shift_

doc_tap_Parallel_shift;

Increases or decreases the curve by defined value.

E.g. if set point temperature based on angle of curve is 37ºC, and parallel shift is set to 4ºC, resulting set point is 41ºC.
