Dhw Control Stop Set Point (I); Dhw Control Option (J); Htg Cut In Temp (N); Boiler Type (P) - REMEHA Quinta 115 Technical Information

Parameter H factory set must not be changed

6.6.10 DHW control stop set point (I)

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

6.6.11 DHW control option (J)

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.
This value sets the dT 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 must not be changed.
Parameter T factory set must not be changed.

6.6.14 Maximum delay time (U)

Adjustable from 00 - 99 minutes.
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.

6.6.15 Start and end point analog signal (Q and Y)

Start point (0 V): adjustable between 5) (-50)°C and +50°C .
This value sets the required flow temp at 0 V signal input (restricted by the min flow
set point).
