Group 1: Integrated equitherm regulation parameters
Equitherm regulation defines the desired value of heating water temperature depending on the outdoor temperature.
The selection of parameters for the calculation depends on the specification of the binary NU (night moderation).
If NU is disconnected, the following is true:
the desired heating water temperature value = (20 – outdoor temperature) * Et1 + 20 + ET2
If NU is connected, the following is true:
the desired value of heating water temperature = (20 – outdoor temperature) * Et3 + 20 + ET4
The desired outlet heating water temperature value is limited in the range between to_ (P3.3) and to¯ (P3.4).
Equitherm regulation always requires the connection of an outdoor temperature sensor and the heating mode setting
of rto = EtE(P3.1=2).
Et1 P1.1Equitherm regulation parameter, curve slope. True for a disconnected NU.
The setting range falls between 0.1 .. 6.0, step of 0.1, leading value is 1.6.
Et2P1.2Equitherm regulation parameter, curve shift. True for a disconnected NU.
The setting range is -20°C .. +40°C, step of 1°C, leading value is 0.
Et3P1.3Equitherm regulation parameter, curve slope. True for a disconnected NU.
The setting range falls between 0.1 .. 6.0, step of 0.1, leading value is 1.6.
Et4P1.4Equitherm regulation parameter, curve shift. True for a connected NU.
The setting range falls between -20°C .. +40°C, step of 1°C, leading value is -5.
Group 2: Integrated room thermostat parameters
An integrated room thermostat can control heating operation according to the data from internal temperature
sensor. It uses proportional control to set the outlet water temperature within the range defined by the tdr (P2.3)
parameter:
- if TM < ti1 - tdr (TM < P2.1 – P2.3), heating is controlled to reach the maximum heating water temperature to¯
(P3.4),
- if TM > ti1 (TM > P2.1), heating is controlled to have the minimum heating water temperature to_ (P3.3),
- if ti1 - tdr < TM < ti1 (P2.1 – P2.3 < TM < P2.1), the desired heating water temperature is calculated by the
interpolation between to_ and to¯ (P3.3a P3.4),
- if TM > ti1 + tdF, the heating is switched off completely.
The aforementioned is true if the NUbinary input specification is “disconnected”. If the NU binary input
specification is “connected”, a value of ti2(P2.2) is used instead of ti1(P2.1).
ti1P2.1Desired value of the room temperature. True if NM is “disconnected”.
The setting range falls between 10 and 30°C, step of 1°C, leading value is 21°C.
ti2P2.2 Desired value of the room temperature. True if NMis “connected”.
The setting range falls between 10 and 30°C, step of 1°C, leading value is 19°C.
