–
DUAL-FUNCTION BOILER
Installation 10/17 supports:
➔
collector pump,
➔
valve switching to a two-state heating boiler
➔
accumulation tank with lower and upper circuit,
➔
dual-function boiler (heating the tank output),
➔
one direction of collector positioning,
➔
additional peripherals.
Installation sensors:
➔
collector sensor,
➔
two sensors of accumulation tank - upper and lower one
The system includes a dual function boiler which heats the circuit. In case of too low tank temperature the valve switches
to the CH boiler.
Additional parameters to be configured (additional submenu in service menu):
•
Options: heating deactivation.

–
CH RETURN HEATING
Installation 11/17 supports:
➔
collector pump,
➔
valve switching between direct boiler circulation and
through-tank circulation or pump
➔
accumulation tank with lower and upper circuit
➔
CH boiler return circuit,
➔
one direction of collector positioning,
➔
additional peripherals (no possibility of cooling with DHW
pump
Installation sensors:
➔
collector sensor,
➔
two sensors of accumulation tank - upper and lower one
➔
CH boiler return sensor.
The system includes a valve which switches into CH boiler return circuit if there is too much hot water in the tank in order
to heat the return circuit (release the excess heat), which results in fuel saving. A pump may be used instead of valve
.
Additional parameters to be configured (additional submenu in service menu):
•
Options: energy return threshold, energy return hysteresis, activation delta, deactivation delta
