Htg Cut In Temp (N) - REMEHA Quinta 30 Technical Information

6.6.12 HTG cut in temp (N)

Adjustable 1) (-10) to 20 °C, factory default 03.
This value sets the ∆t 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 74 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.
6.6.15 Start and end point analog signal (Q and Y)
Start point (0 Volt): adjustable between 5) (-50)°C and +50°C, factory default
00°C.
This value sets the required flow temp at 0 Volt signal input (restricted by the min flow
set point).
End point (10 Volt): adjustable between +51°C and (( (+299)°C, factory default
)0 (100)°C.
This value sets the required flow temp at 10 Volt signal input (restricted by the max
flow set point).
Note: These settings are only applicable when boiler control operation parameter (A)
has the x value set to 4.
