Dhw Control Stop Set Point (I); Dhw Control Option (J); Htg Cut In Temp (N); Boiler Type (P) - REMEHA Quinta 45 Technical Information

which time the flow temp is limited by part load temp set point (parameter $)
Changing the factory default should only be carried out on advice from the service
engineer.
NOTE: When using an external analog (0 -10 V) or 2 wire modulation input, the factory
default 03should be changed to 00.
Parameter H factory set must not be changed

6.6.10 DHW control stop set point (I)

Adjustable from 00 - 30 °C factory default 20°C. Refer to Par. 6.6.7.

6.6.11 DHW control option (J)

Three options 00 - 01 - 02 factory default 00.
This value sets the DHW control option.
00 Three way diverting valve (port A - HTG and Port B - DHW)
01 DHW pump
02 Inverted three way diverting valve (port B - HTG and Port A - DHW)
Parameter L not applicable

6.6.12 HTG cut in temp (N)

Adjustable 1) (-10) to 20 °C, factory default 03.
This value sets the Τ below actual return temp at the moment of control stop during
HTG demand. A control stop occurs when the flow temp equals the flow temp set point
+ 5°C. HTG cut in temperature = actual return temperature at the moment of control
stop (e.g. 60) - parameter N (3) ie 60 - 3 = 57°C. If this takes longer than the
maximum delay time (parameter U), the boiler will restart (unless flow temperature
exceeds flow temperature setpoint).
Parameter O not applicable

6.6.13 Boiler type (P)

Factory default 44 (Quinta 45) and 64 (Quinta 65), must not be changed.
Parameter T factory set must not be changed.

6.6.14 Maximum delay time (U)

Adjustable from 00 - 99 minutes, factory default 15 minutes (15).
This value sets the maximum off time following a control stop. The minimum off time
is preset to a fixed value (150 sec.). A combination of both values is used to prevent
hunting taking place.
