EXCEL CARE CONTROL ICONS ALPHABETIC REFERENCE

EN2B-0184 GE51 R0518 (Europe)
• automatic operation (no wall module or external override no summer- or holiday
switch)
• the electronic caretaker is not active
• no heat override function
• no DHWS priority or condensation protection function
If the parameter P19 set to 2 = ´Restart`, the heating curve slope adaptation will be
restarted. This new start has to be selected before the first download of the
controller or when the building load has been changed after a renovation. After 24
hours of operation, the heating curve slope adaptation will automatically be reset to
the 1 = ´adaptive`.
If the parameter Adaptation is set to 3 = ´refreshed new start`, the heating curve
slope adaptation will be execute a ´Restart` function based on the outside air
temperature values of +10, +5, 0, -5, -10 and -15 °C, etc. This means, when the
average outside air temperature during 48 hours crosses the former mentioned
temperature levels upwards or downwards, the ´Restart` function is activated once
again, as shown in next figure.
Note:
• the parameter remains in the state ´refreshed new start` and will not change to
´Restart`.
• the outside air temperature is not filtered by the EOH3 itself. A calculation of the
outside air temperature average must be done separately.
For direct room temperature compensation, the flow temperature setpoint is
calculated according to the formula:
Tsup = Heating Curve Setpoint + P23*F
ADAPT*
(Tset +/- Toff (CPA) - TRm)
Heating Curve Setpoint = HC(TSet, TOat, P16, P17)
Tsup = 0, for total cool down
F
ADAPT
= 1; if P19 = [0;4]
F
ADAPT
= 0; if P19 = [1;2;3]
