Display Heating

E-heating/Hotgas reheat/Hot

water reheat

Depending on which heating type you

have configured, different parameters

are decisive.

The start temperature for every heating

type is entered as a negative difference to

the room temperature setpoint. ➊

The hysteresis for the heating stop is only

valid for heatings with on/off-control.

➋

For proportional e-heatings/hot water

reheats you can adjust a gradient, which

determines the temperature range in

which the heating capacity increases from

0 to 100%.➌

You can determine, whether the e-heating

alarm releases a common alarm (0 = no,

1 = yes).

➍

The e-heating alarm delay can be adjus-

ted in seconds.

➎

Setting the priority for the heating alarm

➏ means assigning the corresponding

alarm to an alarm relay with the adjusted

number.

Only the ﬁrst heating can be proportional.

If this is the case and if there are several

heatings (up to 4), only the start value

and the gradient of the ﬁrst heating are

decisive for the control. Each time the pro

-

portional heating reaches 100% heating

capacity another reheat is added and the

ﬁrst heating is reset to 0%. This way up to

four individual heatings act as one propor-

tional heating. (See illustration 1).
