The room temperature can be controlled by
ESMR, the remote control ECA 61, or the room
panel ECA 60.
The return temperature measured by S3 can be
limited during heating or during heating and
hot-water charging by S3 (optional).
Reduced flow or room temperatures can be set
for desired periods.
Hot water circuit
The tank temperature is measured by the upper
sensor S6 (cut-in) and by the lower sensor S5
(cut-out). A low S6 temperature causes the
charging pump P2/P4 to start. P2/P4 stops again
when the cut-out temperature is reached at S5.
The motorised valve M2 controls the charging
temperature during hot water heating. The
charging temperature is measured by S4.
The return temperature in the hot water circuit
can be limited by S5 (optional).
Function
Applications
Heating circuit
The motorised valve M1 controls the flow
temperature which is measured by S2.
The flow temperature (2) in the heating circuit is
controlled in relation to the outdoor temperature
measured by S1.
