Group 1 Parameters of equithermal regulation
Equithermal regulation states the required value of the temperature of the heating water depending on the ambient
temperature. The selection of parameters for the calculation depends on the status of binary input NU.
For NM (NU) disconnected, it is valid:
Engaged value of the temperature of heating water = (20 – Outdoor temperature) * EQUITHERM
CONSTANT 1 + 20 + EQUITHERM CONSTANT 2
For NM (NU) connected, it is valid:
Engaged value of the temperature of heating water = (20 – Outdoor temperature) * EQUITHERM
CONSTANT 3 + 20 + EQUITHERM CONSTANT 4
The required value of the temperature of the output water is restricted concerning the range stated by the items
HEATING WATER SETTING –LOWER LIMIT and HEATING WATER LIMIT –UPPER LIMIT of
service menu.
The equitherm regulation requires the connection of an external sensor for the temperature of the service water; the
heating must be set for OTC.
The equitherm regulation parameters are displayed in the user menu only in the case where the heating regime is
set for OTC.
