Heating circuit II
The motorised valve M2 controls the flow
temperature measured by S4.
The flow temperature (S4) in the heating
circuit is controlled in relation to the outdoor
temperature measured by S1.
The room temperaure can be controlled by the
remote control ECA 61 or the room panel ECA 60.
The return temperature (S5) can be limited
during heating.
Reduced flow can be programmed for desired
periods.
Hot water circuit
The motorised valve M1 (applications 1 and 4)
controls the charging temperature measured by
S2.
The tank temperature is measured by the upper
sensor S6 (cut-in) and lower sensor S5 (cut-out).
A low S6 temperature causes the charging pump
P3 to start. Pump P3 stops again when the cut-
out temperature is reached.
The return temperature measured by S3
(applications 1 and 4) can be limited in the
primary circuit.
Function
Applications
Heating circuit I
The motorised valve M1 controls the flow
temperature which is measured by S2.
The flow temperature (S2) in the heating
circuit is controlled in relation to the outdoor
temperature measured by S1.
The room temperature can be controlled by the
remote control ECA 61 or the room panel ECA 60.
The return temperature measured by S3 can be
limited during heating.
Reduced flow or room temperature can be
programmed for desired periods.
