D.h.w. values
5.14 Maximum nominal setpoint of d.h.w.
temperature
• Setting can be limited by the enduser
• Reduced risk of scalding
Minimized proneness to lime buildup
Function for limiting the nominal setpoint of the d.h.w. temperature.
1. Press the line selection buttons to select line 40OEM.
2. Press the + / - buttons to adjust the nominal setpoint of the d.h.w. temperature.
Setting range Unit Factory setting
8...80 °C 60
The setting will ensure maximum limitation of the nominal d.h.w. temperature setpoint
(setting on line 13).

Setting "Maximum nominal setpoint of d.h.w. temperature”
5.15 Switching differential of the d.h.w.
temperature
• Optimum frequency of d.h.w. heating
D.h.w. control is in the form of a two-position controller with an adjustable switching
differential.
The switching differential for d.h.w. control has no impact on d.h.w. with a control
thermostat or changeover valve (via BMU).
1. Press the line selection buttons to select line 41OEM.
2. Press the + / - buttons to adjust the switching differential for d.h.w.
Setting range Unit Factory setting
0...20 °C (K) 5
The setting will change the switching differential of the d.h.w. temperature control.
Entry:
Increase: Switching differential will become larger
Fewer and longer heating up times, larger temperature variations
